Bullseye Glass Co., Emeryville

Founded in 1974 by three "hippie glassblowers," Bullseye Glass Co produces internationally renowned glass materials in thousands of colors and finishes suitable for artistic endeavors of all kinds, such as mosaics and stained glass. Aside from being beautiful to look at, most of Bullseye's glasses are compatible for fusing and kilnforming—something that's especially important for glass artists to know. Bullseye also passes on the ancient art of glass shaping through artist-guided classes. Graduates of these kilnforming classes can return to craft additional treasures or explore the cyclical nature of art by turning a wineglass back into a sandbox.
