"Blue/Ruby Spray" (1990) from Harvey Littleton's Crown Series, is made from colorless and colored barium potash glass, blown, with multiple cased overlays.
Fifty years ago ceramics instructor Harvey Littleton created a workshop in a garage at the Toledo Museum of Art to explore the possibilities of newly-developed small furnaces. Beautiful glass has been around for thousands of years, from ancient Egypt and Rome to Tiffany's in 19th century America. But making it is so difficult that before 1962, artists had to hand over their designs to industrial furnaces to be completed.
All that changed with the Studio Glass movement that grew out of Littleton's modest workshop.
