From French, Exposition Internationale des Arts Décoratifs et Industriels Modernes, an exhibition in Paris in 1925. A style of design that originated in the 1920s and was popular in western Europe and the United States in the 1930s. Art Deco is distinguished by simple, streamlined shapes and
(from Greek, “small amphora”) A small jar with two handles, used for perfume or toilet oil in the pre-Roman and Roman periods. Amphoriskos
A rare type of English wineglass with a drawn stem. The bowl is decorated by diamond-point engraving with verses from the Jacobite hymn followed by the word “Amen,” and with emblems associated with the Jacobite uprising of 1715. Jacobite glass The Mesham Amen Goblet
A type of Art Glass that varies in color from amber to ruby or purple on the same object. This shaded effect is due to the presence of gold in the batch. The object is amber when it emerges from the lehr, but partial reheating causes the affected portion to become red or purple. Amberina, developed
A type of English drinking glass for ale or beer. Ale glasses, first made in the 17th century, have a tall and conical cup, a stem, and a foot. They may be enameled, engraved, or gilded with representations of hops or barley. Ale Glass
A type of translucent white glass, similar to opal glass, first produced in Bohemia in the 19th century. In the 1920s, Frederick Carder (1863- 1963) introduced alabaster glass at Steuben Glass Works in Corning, New York. Carder’s alabaster glass has an iridescent finish made by spraying the object
(1) A group of Mediterranean, Asian, and African plants with large, spiny leaves; hence (2) ornament that resembles the leaves of the species Acanthus spinosus.
Minute bubbles of gas, usually occurring in groups.
Susceptible to being modeled or shaped. When it is in a molten state, glass can be described as plastic.
In glassmaking, a soluble salt consisting mainly of potassium carbonate or sodium carbonate. It is one of the essential ingredients of glass, generally accounting for about 15-20 percent of the batch. The alkali is a flux, which reduces the melting point of the major constituent of glass, silica.
(from Greek lithos, “stone”) A type of glass, developed in Bohemia by Friedrich Egermann (1777-1864), that is opaque and has a marbled surface resembling semiprecious stones. Lithyalin Beaker
Calcined limestone, which, added to batch in small quantities, gives stability. Before the 17th century, when its beneficial effects became known, lime was introduced fortuitously as an impurity in the raw materials. The addition of insufficient lime can cause crizzling.
Composite arrangements of pieces of flat glass that are held together by lead (or sometimes by zinc or some other metal) cames. Stained glass windows are the most prominent examples of leaded glass. Panel with Washington Coat-of-Arms Panel with Washington Coat-of-Arms
Glass that contains a high percentage of lead oxide (at least 20 percent of the batch). In modern times, glass of this type was patented in 1674 by George Ravenscroft (1632-1683), who added a larger amount of lead in 1676. Lead glass is relatively soft, and its refractive index gives a brilliance
(from Greek, “small mixing bowl”) A small vessel with a wide mouth and body, and a foot. The term is often used to describe certain core-formed Egyptian vessels of the second millennium B.C.
A concavity in the base of a vessel, usually made by depressing the base with a tool. The provision of a kick strengthens the bottom of the vessel and reduces the vessel’s capacity. Beaker
(from Italian intarsio, “marquetry”) A type of glass developed by Frederick Carder (1863-1963) about 1920. A design of colored glass was applied to a parison of a different color, then flashed with a second parison of the same color as the first. Intarsia Footed Vase
(Italian) The technique of constructing an object, usually a vessel, by fusing two or more blown glass elements. The process, first practiced in the Islamic world in the Middle Ages, demands great precision because the edges of the adjoining elements must have precisely the same diameter. Giada
A highly corrosive acid that attacks silicates such as glass. Pure hydrofluoric acid dissolves glass, leaving a brilliant, acid-polished surface.
The process of breaking away the edge of a glass object with a grozing iron or pliers in order to shape it.
A type of decorative glass developed by Orrefors of Sweden in 1916. The design is carved, engraved, or etched on a parison of colored glass, which is then reheated and cased in a thick layer of transparent glass of a different color, and inflated.
Decoration that consists of narrow vertical grooves (flutes). Fluted Vase
A misnomer for English and American lead glass. The term came into use in 1674, when George Ravenscroft’s new glass formula included ground, calcined flint as a source of silica. In the 18th and 19th centuries, the term was applied to decolorized glass, even when it contained no flint. Pitcher
Clay capable of being subjected to a high temperature without fusing, and therefore used for making crucibles in which glass batches are melted. Fire clay is rich silica, but it contains only small amounts of lime, iron, and alkali.
The process of completing the forming or decoration of an object. Finishing can take the form of manipulating the object into its final shape while it is hot, of cracking off before annealing, or of cutting, enameling, grinding, or polishing.
