Just finished some great pattern bar plates. The black and white sections of the plate are actually slices of a stack of black and white ( with a little red and yellow) pieces of glass fused together. When laid on their sides and sliced, they make interesting patterns. I hadn’t tried the red for a base but I love the results on this 12″ x 12″ plate. The black plate (5″ x 5″) with the pattern bar lends a zebra style to the project.
