Companies such as Bullseye Glass and Spectrum Glass supply colored glass designed for use in art applications. Other companies such as US Color Glass supply back-painted colored glass meant for commercial and residential architectural purposes.
The colored-art glass supplied by companies such as Bullseye Glass and Spectrum Glass is typically sold in 1/8-inch-thick pieces or sheets. This glass is also not tempered as it primarily made for use in stained glass and warm glass projects. Some of the colored glass sold by US Color Glass is tempered or annealed as it meant for more rugged applications, such as residential or commercial backsplashes.
