Sculptors or mural-artists or artisans working in the medium of glass, could have registered themselves under the category of Glass Art.
Glass art usually refers to large modern works of art, typically one-off creations, which are substantially or wholly made in glass. It is distinguished from art glass and studio glass which are typically smaller and often made in editions of many identical pieces, but the boundaries are not clear-cut. Glass art is more likely to be exhibited in public spaces or large corporate or institutional complexes; rather than in homes.
Artistically decorated, individually commissioned, large glass panels are usually for interior use, often in hotels, cruise liners and restaurants or night clubs. The decorative techniques used would include wheel carving, engraving, frosting, acid-etching, enameling and gilding, often combining techniques by the use of masking or silk-screening.
