Glass art and Glass sculpture is the use of glass as an artistic medium to produce sculptures or two-dimensional artworks. Specific approaches include stained glass, working glass in a torch flame (lamp-working), glass bead-making, glass casting, glass fusing, and, most notably, glass blowing. As a decorative and functional medium, glass was extensively developed in Egypt and Assyria, brought to the fore by the Romans (who developed glassblowing), and includes among its greatest triumphs European cathedral stained glass windows. Great ateliers like Tiffany, Lalique, Daum, Gallé, the Corning schools in upper New York state, and Steuben Glass Works took glass art to the highest levels. Glass from Murano (also known as Venetian glass) is the result of hundreds of years of refinement and invention. While there are now more hot-shops and glass artists working in Seattle (USA), Murano is still held as the birthplace of modern glass art.
