John Lewis founded his studio in 1969. He was one of the first artists to open a hot glass studio in the Bay Area where, for 10 years, his focus was blowing glass. After receiving an NEA grant in 1980, he started experimenting with the possibilities of cast glass as a sculptural medium. He built a furnace specifically for casting, which melted and poured glass, and began exploring the various forms possible with different types of molds. This exploration led John to create a diverse collection of cast glass sculptures, in a variety of shapes, forms, textures and colors.
