"Art glass," often uses the traditional skills of glassblowing to produce glass objects, sometimes in vivid colors and extravagant shapes, which are often meant to be seen more as aesthetic than as utilitarian creations. However, many "art glass" objects may also be created in forms that evoke utilitarian functions, e.g., cups, bowls, trays, paperweights, handwarmers, etc.
"Stained Glass" crafting uses transparent or colored glass, often combined into larger shapes or panels held together by lead "cames," to produce windows or ornaments, which may be abstract combinations of colors and shapes, or representational images. Stained glass has long been used as a special architectural feature, especially in churches, but also in windows or overhead oculuses.
"Fused Glass" crafting involves the fusing or melting together of two or more pieces of glass to create abstract fused glass pieces, as well as pendants, trivets, coasters, picture frames, candy/trinket dishes, candle holders, jewelry, and more.
"Lampwork" jewelry is created by melting glass rods, typically very narrow ones, to form amazing beads. The rods are melted by using an open torch flame.
