Our new glass tiles were just unveiled at Coverings 2012, and are now part of Clay Decor's offerings. We're not abandoning our clay (ever!), but this is a fun new direction of artwork and a chance to experiment with color and light in our relief designs. So far, we have a limited number of our designs, from 1x1 to 21 x 15 Concordia. Designs are incised into the glass as reverse-relief, or can appear almost three dimensional as you see the design in the back through a smooth top layer of glass. Here's a picture of Concordia glass tile framed by glass Ornate Frame Moldings and surrounded by commercial mosaics (from the Coverings display). Little bit of a bear to photograph glass... :)
