The latest addition to Joel Berman Glass Studio's palette of cast-glass designs is Trio, named for its triangular corrugated motif. Launched at the AIA's convention held last May in San Diego, Trio is the third texture of Berman's 3D Studio Line, following a curved corrugated design, known as Corrugated, and an abstract pattern inspired by crumpled paper, called Arrigado. Trio was inspired by Berman's work with pyramid structures in glass in the 1980s, created with glass designer Ludwig Schaffrath, one of the founders of the contemporary architectural glass movement.
