Glass art is the use of glass as an artistic medium. Specific approaches include stained glass, working glass in a torch flame (lampworking), glass beadmaking, glass casting, glass fusing, and, most notably, glass blowing.
The term stained glass refers either to the material of colored glass or to the art and craft of working with glass. Throughout its thousand-year history the term "stained glass" was applied almost exclusively to the windows of churches, cathedrals and other significant buildings. Although traditionally made in flat panels and used as windows, the creations of modern stained glass artists also include three-dimensional structures and sculpture.
