paragraph_text: Trena Mary Cox (1895–1980) was an English stained glass artist. She was born Emma Trina Cox on 3 March 1895, in the Lower Bebington Urban District (i.e. not Bebbington), on the Wirral Peninsula and grew up around Birkenhead. She trained at the Laird School of Art. In 1924 she moved to Chester and set up her studio in Victoria Road Chester, Cheshire, either adjacent to, or within, the Kaleyard works of Williams, Gamon & Co., with whom she remained associated until the Second World War. In about 1945, Trena Cox moved to 96 Watergate Street, Chester, which remained her home and, at least later, her studio, until she retired in 1972 (at the age of 77) and died, on 11 February 1980 (not in 1977, as frequently quoted). Most of her works are in churches in the old counties of Cheshire and Lancashire. She was a fellow of the British Society of Master Glass Painters. The authors of the "Buildings of England" series comment that "her windows are usually small, her figures modest, often with small-scale detail in the quarries" (small pieces of square or diamond-shaped glass set diagonally).

paragraph_text: Louis Grodecki (18 July 1910, Warsaw – 28 March 1982, Paris) was a French art historian. A disciple of Henri Focillon since 1929, shortly after his arrival in France, and naturalized French in 1935, he met art historian Erwin Panofsky in 1949 at the Institute for Advanced Study in Princeton. Grodecki is famous for his work on romanesque stained glass, of Paris, Picardy and the Nord-Pas de Calais region. His most notable works are about the stained glasses of Chartres Cathedral, in particular a complete catalogue which he never finished.

paragraph_text: Other microscopic procedures may also aid in identifying infectious agents. Almost all cells readily stain with a number of basic dyes due to the electrostatic attraction between negatively charged cellular molecules and the positive charge on the dye. A cell is normally transparent under a microscope, and using a stain increases the contrast of a cell with its background. Staining a cell with a dye such as Giemsa stain or crystal violet allows a microscopist to describe its size, shape, internal and external components and its associations with other cells. The response of bacteria to different staining procedures is used in the taxonomic classification of microbes as well. Two methods, the Gram stain and the acid-fast stain, are the standard approaches used to classify bacteria and to diagnosis of disease. The Gram stain identifies the bacterial groups Firmicutes and Actinobacteria, both of which contain many significant human pathogens. The acid-fast staining procedure identifies the Actinobacterial genera Mycobacterium and Nocardia.

paragraph_text: Leadenhall Street Baptist Church is a historic located at Baltimore, Maryland, United States. It is a gable-front rectangular brick temple with simple Renaissance Revival detail. The original exterior wall surfaces have been covered with formstone on the main façade and stucco elsewhere. It features round-arched stained glass windows on each side bay. It was built in 1873, by Joseph Thomas & Son for the city's African American Baptists who were then centered in the old southwest area from the downtown business district of Baltimore in the "Sharp-Leadenhall" (named for the intersecting nearby streets) community in the old "South Baltimore" area. Nearby is its now famed revitalized "Inner Harbor" area of the old "Basin" for the harbor port.

paragraph_text: Transparent Stained-Glass Windows () is the third novel in the Labyrinth trilogy of cyberpunk novels written by Russian science fiction writer Sergey Lukyanenko. Originally published online, the story features two endings, both of which are included when it was printed in the "Atomic Dream" anthology. Unlike the first two novels, Transparent Stained-Glass Windows is told from the point of view of a young female MVD operative who is sent to an isolated area of Deeptown, a virtual city created by Microsoft and IBM, to inspect the first virtual prison and locate any possible breakouts into Deeptown. She soon finds out that the prison is used by the Russian government to secretly conduct experiments on inmates. Throughout the story, she keeps referring to a jigsaw puzzle she began to complete during her childhood but never finished (one piece was missing).

paragraph_text: Snow cover (averaging 3 -- 5 months per year) is formed at the beginning of November and melts in beginning of April, but in recent years snow cover has lasted shorter than usual. For example, in the winter of 2006 -- 2007 the snow cover did n't form until the end of January, and melted at the beginning of March; in 2007 -- 2008, the snow cover melted at the end of February, and in the 2008 -- 2009 winter, snow cover did n't form until the end of December, which is one month later than usual. Yet in 2011 - 2012 it melted in the middle of April.

paragraph_text: The observation that old windows are sometimes found to be thicker at the bottom than at the top is often offered as supporting evidence for the view that glass flows over a timescale of centuries, the assumption being that the glass has exhibited the liquid property of flowing from one shape to another. This assumption is incorrect, as once solidified, glass stops flowing. The reason for the observation is that in the past, when panes of glass were commonly made by glassblowers, the technique used was to spin molten glass so as to create a round, mostly flat and even plate (the crown glass process, described above). This plate was then cut to fit a window. The pieces were not absolutely flat; the edges of the disk became a different thickness as the glass spun. When installed in a window frame, the glass would be placed with the thicker side down both for the sake of stability and to prevent water accumulating in the lead cames at the bottom of the window. Occasionally such glass has been found installed with the thicker side at the top, left or right.

paragraph_text: Lilian Josephine Pocock (1883–1974) was a stained glass artist who provided stained glass for a number of buildings, including Ulverston Victoria High School, The King's School and Ely Cathedral. She was also a theatrical costume designer, book illustrator and watercolourist. In her later years, failing eyesight prevented her from continuing her work in stained glass. After some years of retirement she died in 1974.

paragraph_text: The Christ Church is a historic Episcopal church located at Port Republic, Calvert County, Maryland, United States. The church is a three-bay-wide, five bays long, beige stucco covered structure featuring stained glass in most of the tall paired round-arched sash windows. It is the mother Episcopal Church of Calvert County and its oldest continually worshipping congregation. Middleham Chapel was started from this congregation as a Chapel of Ease. Christ Church Parish was one of the original 30 Anglican parishes in the Province of Maryland. Burials in the church cemetery include former U. S. Representative Thomas Parran, Sr. and United States Coast Guard Admiral Merlin O'Neill.

paragraph_text: Glass remained a luxury material, and the disasters that overtook Late Bronze Age civilizations seem to have brought glass-making to a halt. Indigenous development of glass technology in South Asia may have begun in 1730 BCE. In ancient China, though, glassmaking seems to have a late start, compared to ceramics and metal work. The term glass developed in the late Roman Empire. It was in the Roman glassmaking center at Trier, now in modern Germany, that the late-Latin term glesum originated, probably from a Germanic word for a transparent, lustrous substance. Glass objects have been recovered across the Roman empire in domestic, industrial and funerary contexts.[citation needed]

paragraph_text: The clock and dials were designed by Augustus Pugin. The clock dials are set in an iron frame 23 feet (7.0 m) in diameter, supporting 312 pieces of opal glass, rather like a stained-glass window. Some of the glass pieces may be removed for inspection of the hands. The surround of the dials is gilded. At the base of each clock dial in gilt letters is the Latin inscription:

paragraph_text: Written in 2005, Moscow, Rough Draft by Sergey Lukyanenko is a fantasy novel of the "parallel world" genre. It was followed by "Final Draft".

paragraph_text: Red was the color of the banner of the Byzantine emperors. In Western Europe, Emperor Charlemagne painted his palace red as a very visible symbol of his authority, and wore red shoes at his coronation. Kings, princes and, beginning in 1295, Roman Catholic cardinals began to wear red costumes. When Abbe Suger rebuilt Saint Denis Basilica outside Paris in the early 12th century, he added stained glass windows colored blue cobalt glass and red glass tinted with copper. Together they flooded the basilica with a mystical light. Soon stained glass windows were being added to cathedrals all across France, England and Germany. In Medieval painting red was used to attract attention to the most important figures; both Christ and the Virgin Mary were commonly painted wearing red mantles.

paragraph_text: The George H. Miller House is a historic house located at 405 W. Market St. in Bloomington, Illinois. Prominent local architect George H. Miller built the house in 1890 for himself and his family. Miller designed many new buildings in downtown Bloomington after a 1900 fire destroyed much of the area; he also served as Superintendent of U.S. Buildings and designed many federal buildings in the Midwest. Miller's house is an eclectic variation on the Queen Anne design. The house features a hexagonal tower on its southeast corner and a conical dormer projecting from the front of the multi-component roof. The front entrance is arched and flanked by columns; small recessed porches are located above the entrance and on the east side of the house. The house has several stained glass windows, including a window with Miller's name at the front entrance and a large circular window on the west side.

paragraph_text: Jessie Bayes (b. 1876 Hampstead, London - d. 1970) was a British Arts & Crafts artist who specialized in miniature paintings, illuminated manuscripts, stained glass, iconography and more.

paragraph_text: Many applications of silicate glasses derive from their optical transparency, which gives rise to one of silicate glasses' primary uses as window panes. Glass will transmit, reflect and refract light; these qualities can be enhanced by cutting and polishing to make optical lenses, prisms, fine glassware, and optical fibers for high speed data transmission by light. Glass can be colored by adding metallic salts, and can also be painted and printed with vitreous enamels. These qualities have led to the extensive use of glass in the manufacture of art objects and in particular, stained glass windows. Although brittle, silicate glass is extremely durable, and many examples of glass fragments exist from early glass-making cultures. Because glass can be formed or molded into any shape, and also because it is a sterile product, it has been traditionally used for vessels: bowls, vases, bottles, jars and drinking glasses. In its most solid forms it has also been used for paperweights, marbles, and beads. When extruded as glass fiber and matted as glass wool in a way to trap air, it becomes a thermal insulating material, and when these glass fibers are embedded into an organic polymer plastic, they are a key structural reinforcement part of the composite material fiberglass. Some objects historically were so commonly made of silicate glass that they are simply called by the name of the material, such as drinking glasses and reading glasses.

paragraph_text: Gabriel Loire (April 21, 1904 – December 25, 1996) was a French stained glass artist of the twentieth century whose extensive works, portraying various persons or historical scenes, appear in many venues around the world. He founded the Loire Studio in Chartres, France which continues to produce stained glass windows. Loire was a leader in the modern use of "slab glass" (French: "dalle de verre"), which is much thicker and stronger than the stained glass technique of the Middle Ages. The figures in his windows are mostly Impressionistic in style.

paragraph_text: From the 19th century, there was a revival in many ancient glass-making techniques including cameo glass, achieved for the first time since the Roman Empire and initially mostly used for pieces in a neo-classical style. The Art Nouveau movement made great use of glass, with René Lalique, Émile Gallé, and Daum of Nancy producing colored vases and similar pieces, often in cameo glass, and also using luster techniques. Louis Comfort Tiffany in America specialized in stained glass, both secular and religious, and his famous lamps. The early 20th-century saw the large-scale factory production of glass art by firms such as Waterford and Lalique. From about 1960 onwards there have been an increasing number of small studios hand-producing glass artworks, and glass artists began to class themselves as in effect sculptors working in glass, and their works as part fine arts.

paragraph_text: Evidence of stained glass windows in churches and monasteries in Britain can be found as early as 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.

paragraph_text: At the east end of the Lady Chapel is a memorial chapel to the airmen of the RAF who were killed in the Second World War. It incorporates a memorial window to the Battle of Britain, which replaces an earlier Tudor stained glass window destroyed in the war.
