Graham Caldwell makes many of his glass sculptures in his workshop near Washington, D.C. There, you can watch him put red-hot liquid glass on a metal stick called a blowpipe. He expertly forms the glass in different ways by blowing air through the blowpipe opening. He can stretch the glass into long shapes or let it hang down so that gravity does the work. But Caldwell’s art is not usually just one single piece of sculpture. Each work is made up of many similar parts. Graham Caldwell recently had a show at an art gallery in Washington. One work was made up of pointy glass pieces that looked like the shape of elephant tusks. They were attached to the wall by round metal bases. Caldwell arranged these sharp, curved pieces in a circle so that all the points were going in the same direction. It looked like the open mouth of an angry sea creature. Another work was made up of many slightly different silvery glass forms that looked like tear drops coming out of the wall. Each glass drop reflected the silvery shape next to it. When you stood near the rounded forms, you could see yourself and the whole room reflected in the glass. Graham Caldwell said the piece is about the "intelligibility of reflections." This striking artwork keeps you looking, wondering, and exploring.
