Bob Snodgrass is an American lampworker known for his contributions to the art of glass pipe-making and glass art. He began working on his techniques while following the Grateful Dead on tour during the 1970s and ’80s. In 1981, glassblowing became Snodgrass’s main trade. He and his family began traveling in the United States, selling his work at art markets until 1990 when they settled in Eugene, Oregon. Snodgrass is credited with having invented (by accident, he says) color changing glass, a type of borosilicate glass mixed (fumed) with gold, silver, platinum, or any combination which changes colors as the dark resin builds up on the inside of the glass. He has been called the “Godfather of glass.”
