Terry Crider and his wife Donna, began creating glass art in 1976. They sold their first pieces at flea markets. Terry had a chemistry background and he worked to develop a special formula for iridizing some of his glass. He made unique paperweights with each piece being 100% hand made and his unique iridizing formula resulted in many one of a kind pieces. Lawyered glass has an simple, but lovely geomertric design. Bottom is marked by artist and date. Is approx 3" x 3" x 4" and is in good, vintage shape with only minor scuffs/wear.
