Here are two photos of the same piece of glass with different lighting. The piece is massive, standing 15 1/2" tall and weighs 33 pounds. Imagine feeding this monster in and out of the furnace for a couple of hours! Talk about a workout. I'm not sure exactly how many layers of glass there are on the piece, but there are SEVERAL. The artist is John Lotton. This type of work is his most desirable for certain.
