75-541: The courthouse was used as the primary seat of government for Hudson County from its opening on September 20, 1910 until the construction of the Hudson County Administration Building in 1966. The courthouse was vacant for many years and was scheduled for demolition . The building was added to the National Register of Historic Places on August 25, 1970. Restoration began in the mid-1970s, and

150-481: A brushable texture, with a binder such as gum arabic . This was painted on the pieces of coloured glass, and then fired to burn away the ingredients giving texture, leaving a layer of the glass and colouring, fused to the main glass piece. "Silver stain", introduced soon after 1300, produced a wide range of yellow to orange colours; this is the "stain" in the term "stained glass". Silver compounds (notably silver nitrate ) are mixed with binding substances, applied to

225-521: A different colour). In medieval glass flashing was especially used for reds, as glass made with gold compounds was very expensive and tended to be too deep in colour to use at full thickness. Another group of techniques give additional colouring, including lines and shading, by treating the surfaces of the coloured sheets, and often fixing these effects by a light firing in a furnace or kiln. These methods may be used over broad areas, especially with silver stain, which gave better yellows than other methods in

300-499: A direct appointment as architect. No competition or bidding for designs was held, causing controversy among local architects. The property on which the courthouse stands was obtained from fourteen separate property owners between 1905 and 1914. The chairman of the Court House Commission, Alexander J. Clements and several other local politicians were later indicted for graft. The groundbreaking took place on March 21, 1906 and

375-761: A great demand for the revival of the art of stained glass window making. Among the earliest 19th-century English manufacturers and designers were William Warrington and John Hardman of Birmingham, whose nephew, John Hardman Powell, had a commercial eye and exhibited works at the Philadelphia Exhibition of 1876, influencing stained glass in the United States of America. Other manufacturers included William Wailes , Ward and Hughes , Clayton and Bell , Heaton, Butler and Bayne and Charles Eamer Kempe . A Scottish designer, Daniel Cottier , opened firms in Australia and

450-454: A more Classical manner, and characterised by the brilliant cerulean colour of the blue backgrounds (as against the purple-blue of the glass of Chartres) and the use of pink and mauve glass. During the mid- to late 19th century, many of Germany's ancient buildings were restored, and some, such as Cologne Cathedral , were completed in the medieval style. There was a great demand for stained glass. The designs for many windows were based directly on

525-566: A museum. Another proposal would house a branch of the New Jersey State Museum in the building. Conrad led a citizens group that lobbied for the preservation of the building, and got it listed on the National Register of Historic Places. The award-winning restoration project resulted in the courthouse being reopened in 1985 for the use of the civil courts and other county offices. The Hudson County Board of Chosen Freeholders renamed

600-438: A number of resources to use and the work of centuries of other artists from which to learn as they continue the tradition in new ways. In the late 19th and 20th centuries there have been many innovations in techniques and in the types of glass used. Many new types of glass have been developed for use in stained glass windows, in particular Tiffany glass and dalle de verre . The primary method of including colour in stained glass

675-442: A rigid frame. Painted details and yellow stain are often used to enhance the design. The term stained glass is also applied to windows in enamelled glass in which the colors have been painted onto the glass and then fused to the glass in a kiln; very often this technique is only applied to parts of a window. Stained glass, as an art and a craft , requires the artistic skill to conceive an appropriate and workable design, and

750-644: A slightly mauve tint, characteristic of the glass in older houses in New England . Selenium has been used for the same purpose. While very pale green is the typical colour of transparent glass, deeper greens can be achieved by the addition of Iron(II) oxide which results in a bluish-green glass. Together with chromium it gives glass of a richer green colour, typical of the glass used to make wine bottles . The addition of chromium yields dark green glass, suitable for flashed glass. Together with tin oxide and arsenic it yields emerald green glass. The first stage in

825-409: A stain known as "Cousin's rose" was used to enhance flesh tones. In the 16th century, a range of glass stains were introduced, most of them coloured by ground glass particles. They were a form of enamelled glass . Painting on glass with these stains was initially used for small heraldic designs and other details. By the 17th century a style of stained glass had evolved that was no longer dependent upon

900-423: A thin layer of red glass to a thicker body of glass that is clear or lightly tinted, forming " flashed glass ". A lightly coloured molten gather is dipped into a pot of molten red glass, which is then blown into a sheet of laminated glass using either the cylinder (muff) or the crown technique described above. Once this method was found for making red glass, other colours were made this way as well. A great advantage

975-491: A traditional type, it is usually left to the discretion of the designer to fill the surrounding areas with borders, floral motifs and canopies. A full-sized cartoon is drawn for every "light" (opening) of the window. A small church window might typically have two lights, with some simple tracery lights above. A large window might have four or five lights. The east or west window of a large cathedral might have seven lights in three tiers, with elaborate tracery. In medieval times

1050-400: Is (as defined by Brewer's Politics ) "the building, complex of buildings or the city from which a government exercises its authority ". In most countries, the nation's capital is also seat of its government, thus that city is appropriately referred to as the national seat of government. The terms are not however, completely synonymous, as some countries ' seat of government differs from

1125-530: Is a murky mustard color but glows purple-red to transmitted light, and the cameo glass Portland vase which is midnight blue, with a carved white overlay. In early Christian churches of the 4th and 5th centuries, there are many remaining windows which are filled with ornate patterns of thinly-sliced alabaster set into wooden frames, giving a stained-glass like effect. Evidence of stained-glass windows in churches and monasteries in Britain can be found as early as

1200-403: Is coloured by adding metallic oxide powders or finely divided metals while it is in a molten state. Copper oxides produce green or bluish green, cobalt makes deep blue, and gold produces wine red and violet glass. Much of modern red glass is produced using copper, which is less expensive than gold and gives a brighter, more vermilion shade of red. Glass coloured while in the clay pot in the furnace

1275-418: Is known as pot metal glass, as opposed to flashed glass . Using a blow-pipe , a glass maker will gather a glob of molten glass that was taken from the pot heating in the furnace. The 'gather' is formed to the correct shape and a bubble of air blown into it. Using metal tools, molds of wood that have been soaking in water, and gravity, the gather is manipulated to form a long, cylindrical shape. As it cools, it

1350-447: Is now sometimes used instead of lead. For further technical details, see Came glasswork . Traditionally, when a window was inserted into the window space, iron rods were put across it at various points to support its weight. The window was tied to these rods with lead strips or, more recently, with copper wires. Some very large early Gothic windows are divided into sections by heavy metal frames called ferramenta . This method of support

1425-458: Is reheated so that the manipulation can continue. During the process, the bottom of the cylinder is removed. Once brought to the desired size it is left to cool. One side of the cylinder is opened, and the cylinder is then put into another oven to quickly heat and flatten it, and then placed in an annealer to cool at a controlled rate, making the material more stable. "Hand-blown" or "mouth-blown" cylinder (also called muff glass) and crown glass were

1500-415: Is still made today, but not on a large scale. Rolled glass (sometimes called "table glass") is produced by pouring molten glass onto a metal or graphite table and immediately rolling it into a sheet using a large metal cylinder, similar to rolling out a pie crust. The rolling can be done by hand or by machine. Glass can be "double rolled", which means it is passed through two cylinders at once (similar to

1575-468: Is that the double-layered glass can be engraved or abraded to reveal the clear or tinted glass below. The method allows rich detailing and patterns to be achieved without needing to add more lead-lines, giving artists greater freedom in their designs. A number of artists have embraced the possibilities flashed glass gives them. For instance, 16th-century heraldic windows relied heavily on a variety of flashed colours for their intricate crests and creatures. In

1650-412: Is to use glass, originally colourless, that has been given colouring by mixing with metal oxides in its melted state (in a crucible or "pot"), producing glass sheets that are coloured all the way through; these are known as "pot metal" glass. A second method, sometimes used in some areas of windows, is flashed glass , a thin coating of coloured glass fused to colourless glass (or coloured glass, to produce

1725-710: The Aube department alone. At the Reformation in England, large numbers of medieval and Renaissance windows were smashed and replaced with plain glass. The Dissolution of the Monasteries under Henry VIII and the injunctions of Thomas Cromwell against "abused images" (the object of veneration) resulted in the loss of thousands of windows. Few remain undamaged; of these the windows in the private chapel at Hengrave Hall in Suffolk are among

1800-460: The Bible , history, or literature; may represent saints or patrons, or use symbolic motifs, in particular armorial. Windows within a building may be thematic, for example: within a church – episodes from the life of Christ ; within a parliament building – shields of the constituencies; within a college hall – figures representing the arts and sciences; or within a home – flora, fauna, or landscape. During

1875-468: The French Revolution . During the 19th century a great number of churches were restored by Viollet-le-Duc . Many of France's finest ancient windows were restored at that time. From 1839 onwards much stained glass was produced that very closely imitated medieval glass, both in the artwork and in the nature of the glass itself. The pioneers were Henri Gèrente and André Lusson. Other glass was designed in

1950-470: The cornerstone was laid on December 12, 1906. Construction of the building was done by Wells Brothers of New York City and construction of the interiors and finishes were by John Gill & Son of Cleveland, Ohio . The courthouse is constructed of granite quarried in Hallowell, Maine . The front of the building is visually dominated by four Corinthian columns and a frieze above the main entrance bearing

2025-736: The groined ceilings. Edwin Blashfield painted the glass dome and the four pendentives between its supporting arches . The Tudor-style legislative chamber of the Board of Freeholders on the second floor was adorned with murals by Howard Pyle depicting early life of the Dutch and English in New Jersey. This room has been called "one of the handsomest legislative chambers in the United States." David G. Lowe, writing in American Heritage magazine, described

2100-457: The "Bishop's Eye" at Lincoln Cathedral . While stained glass was widely manufactured, Chartres was the greatest centre of stained glass manufacture, producing glass of unrivalled quality. Probably the earliest scheme of stained glass windows that was created during the Renaissance was that for Florence Cathedral, devised by Lorenzo Ghiberti . The scheme includes three ocular windows for

2175-457: The 7th century. The earliest known reference dates from 675 AD when Benedict Biscop imported workmen from France to glaze the windows of the monastery of St Peter which he was building at Monkwearmouth . Hundreds of pieces of coloured glass and lead, dating back to the late 7th century, have been discovered here and at Jarrow . In the Middle East, the glass industry of Syria continued during

2250-470: The 7th-century BC. The Kitab al-Durra al-Maknuna , attributed to the 8th century alchemist Jābir ibn Hayyān , discusses the production of colored glass in ancient Babylon and Egypt. The Kitab al-Durra al-Maknuna also describes how to create colored glass and artificial gemstones made from high-quality stained glass. The tradition of stained glass manufacture has continued, with mosques, palaces, and public spaces being decorated with stained glass throughout

2325-715: The Basílica Nuestra Señora de Lourde and the Templo Vótivo de Maipú both located in Chile. The Catholic revival in England, gaining force in the early 19th century with its renewed interest in the medieval church, brought a revival of church building in the Gothic style, claimed by John Ruskin to be "the true Catholic style". The architectural movement was led by Augustus Welby Pugin . Many new churches were planted in large towns and many old churches were restored. This brought about

2400-718: The Hudson County Bar Association ; in the past it has been used in a number of television programs and movies, including scenes in the television series Law & Order , the Joker , and for commercials. The Courthouse was designed by Jersey City native Hugh Roberts , twice a president of the New Jersey Chapter of the American Institute of Architects . Roberts, brother-in-law of future United States Senator and New Jersey Governor Edward I. Edwards , received

2475-585: The Islamic period with major centres of manufacture at Raqqa , Aleppo and Damascus and the most important products being highly transparent colourless glass and gilded glass, rather than coloured glass. The creation of stained glass in Southwest Asia began in ancient times. One of the region's earliest surviving formulations for the production of colored glass comes from the Assyrian city of Nineveh , dating to

2550-555: The Islamic world. The stained glass of Islam is generally non-pictorial and of purely geometric design, but may contain both floral motifs and text. Stained glass creation had flourished in Persia (now Iran) during the Safavid dynasty (1501–1736 A.D.), and Zand dynasty (1751–1794 A.D.). In Persia stained glass sash windows are called Orosi windows (or transliterated as Arasi, and Orsi), and were once used for decoration, as well as controlling

2625-487: The Middle Ages. Alternatively they may be used for painting linear effects, or polychrome areas of detail. The most common method of adding the black linear painting necessary to define stained glass images is the use of what is variously called "glass paint", "vitreous paint", or " grisaille paint". This was applied as a mixture of powdered glass, iron or rust filings to give a black colour, clay, and oil, vinegar or water for

2700-546: The US. In France there was a greater continuity of stained glass production than in England. In the early 19th century most stained glass was made of large panes that were extensively painted and fired, the designs often being copied directly from oil paintings by famous artists. In 1824 the Sèvres porcelain factory began producing stained glass to supply the increasing demand. In France many churches and cathedrals suffered despoliation during

2775-685: The building was reopened in 1985. In 1984, the Hudson County Board of Chosen Freeholders renamed the building in honor of Supreme Court Justice William J. Brennan Jr. The restoration of the courthouse was acknowledged by a Victorian Society in America Preservation Award in 1988. As of 2019 the courthouse has eight working courtrooms and also houses the offices of the County Executive , the Hudson County Surrogate and

2850-643: The capital. The Netherlands , for example, has Amsterdam as its capital but The Hague is the seat of government; and the Philippines , with Manila as its capital but the metropolitan area of the same name (Metro Manila; also known as National Capital Region (NCR)), is the seat of government. Local and regional authorities usually have a seat, called an administrative centre , as well. Terms for seats of local government of various levels and in various countries include: Examples of seats of government include: There are several countries where, for various reasons,

2925-408: The cartoon was drawn directly on the surface of a whitewashed table, which was then used as a pattern for cutting, painting and assembling the window. The cartoon is then divided into a patchwork, providing a template for each small glass piece. The exact position of the lead which holds the glass in place is also noted, as it is part of the calculated visual effect. Each piece of glass is selected for

3000-473: The clothes wringers on older washing machines) to yield glass of a specified thickness (typically about 1/8" or 3mm). The glass is then annealed. Rolled glass was first commercially produced around the mid-1830s and is widely used today. It is often called cathedral glass , but this has nothing to do with medieval cathedrals, where the glass used was hand-blown. Architectural glass must be at least ⁠ 1 / 8 ⁠ of an inch (3 mm) thick to survive

3075-555: The courthouse in 1984 in honor of Associate Supreme Court Justice William J. Brennan, who had served in the building as Hudson County Assignment Judge from 1947 through 1951. Following the 1989 Supreme Court decision in Texas v. Johnson , which Brennan authored, veterans groups petitioned unsuccessfully to have the name removed, but the Freeholders unanimously voted to retain the name.

3150-747: The cupola windows has since been lost, and that by Donatello has lost nearly all of its painted details. In Europe, stained glass continued to be produced; the style evolved from the Gothic to the Classical, which is well represented in Germany, Belgium and the Netherlands, despite the rise of Protestantism . In France, much glass of this period was produced at the Limoges factory, and in Italy at Murano , where stained glass and faceted lead crystal are often coupled together in

3225-399: The decorated surface to the atmosphere or mechanical damage. Once the glass is cut and painted, the pieces are assembled by slotting them into H-sectioned lead cames. All the joints are then soldered together and the glass pieces are prevented from rattling and the window made weatherproof by forcing a soft oily cement or mastic between the glass and the cames. In modern windows, copper foil

3300-409: The design, the structure of the window, the nature and size of the glass available and his or her own preferred technique. A traditional narrative window has panels which relate a story. A figurative window could have rows of saints or dignitaries. Scriptural texts or mottoes are sometimes included and perhaps the names of the patrons or the person to whose memory the window is dedicated. In a window of

3375-491: The desired colour and cut to match a section of the template. An exact fit is ensured by "grozing" the edges with a tool which can nibble off small pieces. Details of faces, hair and hands can be painted onto the inner surface of the glass using a special glass paint which contains finely ground lead or copper filings, ground glass, gum arabic and a medium such as wine, vinegar or (traditionally) urine. The art of painting details became increasingly elaborate and reached its height in

3450-555: The dome and three for the facade which were designed from 1405 to 1445 by several of the most renowned artists of this period: Ghiberti , Donatello , Uccello and Andrea del Castagno . Each major ocular window contains a single picture drawn from the Life of Christ or the Life of the Virgin Mary , surrounded by a wide floral border, with two smaller facade windows by Ghiberti showing the martyred deacons, St Stephen and St Lawrence . One of

3525-630: The early 1600s; the earliest is the work of Dirck Crabeth and his brother Wouter . Many of the original cartoons still exist. Stained glass was first imported to Latin America during the 17th–18th centuries by Portuguese and Spanish settlers. By the 20th century, many European artists had begun to establish their own studios within Latin America and had started up local production. With these new local studios came inventive techniques and less traditional imagery. Examples of these more modern works of art are

3600-413: The early 20th century. From 1300 onwards, artists started using "silver stain" which was made with silver nitrate . It gave a yellow effect ranging from pale lemon to deep orange. It was usually painted onto the outside of a piece of glass, then fired to make it permanent. This yellow was particularly useful for enhancing borders, canopies and haloes, and turning blue glass into green glass. By about 1450,

3675-686: The eastern end of Canterbury Cathedral . As Gothic architecture developed into a more ornate form, windows grew larger, affording greater illumination to the interiors, but were divided into sections by vertical shafts and tracery of stone. This elaboration of form reached its height of complexity in the Flamboyant style in Europe, and windows grew still larger with the development of the Perpendicular style in England and Rayonnant style in France. Integrated with

3750-458: The engineering skills to assemble the piece. A window must fit snugly into the space for which it is made, must resist wind and rain, and also, especially in the larger windows, must support its own weight. Many large windows have withstood the test of time and remained substantially intact since the Late Middle Ages . In Western Europe , together with illuminated manuscripts , they constitute

3825-435: The famous lamps of Louis Comfort Tiffany . As a material stained glass is glass that has been colored by adding metallic salts during its manufacture, and usually then further decorating it in various ways. The colored glass is crafted into stained glass windows in which small pieces of glass are arranged to form patterns or pictures, held together (traditionally) by strips of lead, called cames or calms, and supported by

3900-420: The finest. With the latter wave of destruction the traditional methods of working with stained glass died, and were not rediscovered in England until the early 19th century. See Stained glass – British glass, 1811–1918 for more details. In the Netherlands a rare scheme of glass has remained intact at Grote Sint-Jan Church, Gouda . The windows, some of which are 18 metres (59 feet) high, date from 1555 to

3975-400: The glass paint away to make the design, or the lettering of an inscription. This was the most common method of making inscriptions in early medieval glass, giving white or light letters on a black background, with later inscriptions more often using black painted letters on a transparent glass background. These are the colours in which the glass itself is made, as opposed to colours applied to

4050-504: The glass some protection against weathering, although this can also be true for paint. They were also probably fired separately, the stain needing a lower heat than the paint. "Sanguine", "carnation", "Rouge Jean Cousin " or "Cousin's rose", after its supposed inventor, is an iron-based fired paint producing red colours, mainly used to highlight small areas, often on flesh. It was introduced around 1500. Copper stain, similar to silver stain but using copper compounds, also produced reds, and

4125-481: The glass. Ordinary soda-lime glass appears colourless to the naked eye when it is thin, although iron oxide impurities produce a green tint which becomes evident in thick pieces or with the aid of scientific instruments. A number of additives are used to reduce the green tint, particularly if the glass is to be used for plain window glass, rather than stained glass windows. These additives include manganese dioxide which produces sodium permanganate , and may result in

4200-641: The incoming sunlight in the hot and semi-arid climate. Stained glass, as an art form, reached its height in the Middle Ages when it became a major pictorial form used to illustrate the narratives of the Bible to a largely illiterate populace. In the Romanesque and Early Gothic period, from about 950 to 1240, the untraceried windows demanded large expanses of glass which of necessity were supported by robust iron frames, such as may be seen at Chartres Cathedral and at

4275-560: The inscription "Precedent Makes Law; If You Stand Well, Stand Still." Roberts delegated the assignment of artwork to the muralist Francis David Millet , noted for his work as decorations director for the 1893 World's Columbian Exposition in Chicago ; Millet assigned himself two lunettes on the third floor and a dozen small panels in the second floor corridors. Also on the third floor, Millet assigned two lunettes to Charles Yardley Turner , as well as eight more to Kenyon Cox . Cox also provided

4350-418: The interior of the building: The courthouse interior is a rush of color—pearl gray and green-veined marbles, golden light fixtures, yellow, green, and blue paint. Standing in the great central court, one looks up the three stories of the magnificent rotunda to a dome whose outer rim is painted with the signs of the zodiac and whose center is an eye of stained glass worthy of Tiffany. One feels—as one does in

4425-425: The late medieval period , glass factories were set up where there was a ready supply of silica , the essential material for glass manufacture. Silica requires a very high temperature to melt, something not all glass factories were able to achieve. Such materials as potash , soda , and lead can be added to lower the melting temperature. Other substances, such as lime , are added to make the glass more stable. Glass

4500-464: The lofty verticals of Gothic cathedrals and parish churches, glass designs became more daring. The circular form, or rose window , developed in France from relatively simple windows with openings pierced through slabs of thin stone to wheel windows, as exemplified by the west front of Chartres Cathedral, and ultimately to designs of enormous complexity, the tracery being drafted from hundreds of different points, such as those at Sainte-Chapelle , Paris and

4575-424: The major form of medieval pictorial art to have survived. In this context, the purpose of a stained glass window is not to allow those within a building to see the world outside or even primarily to admit light but rather to control it. For this reason stained glass windows have been described as "illuminated wall decorations". The design of a window may be abstract or figurative; may incorporate narratives drawn from

4650-488: The medieval period the glass was abraded; later, hydrofluoric acid was used to remove the flash in a chemical reaction (a very dangerous technique), and in the 19th century sandblasting started to be used for this purpose. There are a number of glass factories, notably in Germany, the United States, England, France, Poland and Russia, which produce high-quality glass, both hand-blown (cylinder, muff, crown) and rolled (cathedral and opalescent). Modern stained-glass artists have

4725-515: The official capital and de facto seat of government are separated: Stained glass Stained glass is colored glass as a material or works created from it. Although, it is traditionally made in flat panels and used as windows, the creations of modern stained glass artists also include three-dimensional structures and sculpture . Modern vernacular usage has often extended the term "stained glass" to include domestic lead light and objets d'art created from foil glasswork exemplified in

4800-462: The process. The centre of each piece of glass, known as the "bull's-eye", is subject to less acceleration during spinning, so it remains thicker than the rest of the sheet. It also has the pontil mark , a distinctive lump of glass left by the "pontil" rod, which holds the glass as it is spun out. This lumpy, refractive quality means the bulls-eyes are less transparent, but they have still been used for windows, both domestic and ecclesiastical. Crown glass

4875-476: The production of a window is to make, or acquire from the architect or owners of the building, an accurate template of the window opening that the glass is to fit. The subject matter of the window is determined to suit the location, a particular theme, or the wishes of the patron. A small design called a Vidimus (from Latin "we have seen") is prepared which can be shown to the patron. A scaled model maquette may also be provided. The designer must take into account

4950-400: The push and pull of typical wind loads. However, in the creation of red glass, the colouring ingredients must be of a certain concentration, or the colour will not develop. This results in a colour so intense that at the thickness of ⁠ 1 / 8 ⁠ inch (3 mm), the red glass transmits little light and appears black. The method employed to create red stained glass is to laminate

5025-539: The rotunda at the heart of the Capitol in Washington—the dignity of government and the permanence of law. Plans for restoring the courthouse had been proposed even before it fell into disuse. In 1961, the architectural modelist Theodore Conrad proposed converting the building into a new city hall for Jersey City. The plan would have created a mall in front of the building and surrounded it with additional city buildings and

5100-524: The same window. The French Revolution brought about the neglect or destruction of many windows in France. Nonetheless, the country still holds the largest set of Renaissance stained glass in its churches, particularly in the regions of Normandy and Champagne where there were vivid ateliers in many cities until the early 17th century with the stained glass painter Linard Gonthier being active in Troyes until 1642 . There are 1042 preserved 16th-century windows in

5175-509: The skilful cutting of coloured glass into sections. Scenes were painted onto glass panels of square format, like tiles. The colours were then annealed to the glass before the pieces were assembled. A method used for embellishment and gilding is the decoration of one side of each of two pieces of thin glass, which are then placed back to back within the lead came . This allows for the use of techniques such as Angel gilding and Eglomise to produce an effect visible from both sides but not exposing

5250-407: The surface of glass, and then fired in a furnace or kiln. They can produce a range of colours from orange -red to yellow. Used on blue glass they produce greens. The way the glass is heated and cooled can significantly affect the colours produced by these compounds. The chemistry involved is complex and not well understood. The chemicals actually penetrate the glass they are added to a little way, and

5325-418: The technique therefore gives extremely stable results. By the 15th century it had become cheaper than using pot metal glass and was often used with glass paint as the only colour on transparent glass. Silver stain was applied to the opposite face of the glass to silver paint, as the two techniques did not work well one on top of the other. The stain was usually on the exterior face, where it appears to have given

5400-589: The types used in the traditional fabrication of stained-glass windows. Crown glass is hand-blown glass created by blowing a bubble of air into a gather of molten glass and then spinning it, either by hand or on a table that revolves rapidly like a potter's wheel . The centrifugal force causes the molten bubble to open up and flatten. It can then be cut into small sheets. Glass formed this way can be either coloured and used for stained-glass windows, or uncoloured as seen in small paned windows in 16th- and 17th-century houses. Concentric, curving waves are characteristic of

5475-460: The work of famous engravers such as Albrecht Dürer . Original designs often imitate this style. Much 19th-century German glass has large sections of painted detail rather than outlines and details dependent on the lead. The Royal Bavarian Glass Painting Studio was founded by Ludwig I in 1827. A major firm was Mayer of Munich , which commenced glass production in 1860, and is still operating as Franz Mayer of Munich, Inc. . German stained glass found

5550-619: Was also favoured for large, usually painted, windows of the Baroque period. Coloured glass has been produced since ancient times. Both the Egyptians and the Romans excelled at the manufacture of small colored glass objects. Phoenicia was important in glass manufacture with its chief centres Sidon , Tyre and Antioch . The British Museum holds two of the finest Roman pieces, the Lycurgus Cup , which
