Large and unique optical glass sculpture by Steven Weinberg. One of a kind signed by the artist in 1999. Some copper paint flaking at the edge. Cool heavy crystal sculpture! Measurements: 6.5" x 6.5" x 6.5" in size. Third party shipping required. Artist Biography: Steven Weinberg learned to cast optical glass from Eric Hilton, one of his professors at Alfred University. Weinberg was responsible for the invention and design of a great deal of machinery for casting glass, as there was limited technology in the field when he started out in the 1970s. While visiting Central Mexico, he explored the "compelling" ruins of Mayan sites, and the construction and geometric shapes in these ruins frequently appear in his sculptures. Weinberg works primarily within a cube form and enjoys the control needed for working within such a precise shape.
