The tile wall art allows Bob to deal with scale, ideas, and exhibition spaces that were previously unavailable to me. Bob has been able to expand on layering surface textures and melting of glass over glazes adding depth. The use of mirrors add an energy as well as the reflective qualities. The addition of text has given him the opportunity to add texture from a distance and messages up close. The best part is the challenge of scale and competing for wall space in the galleries.
