Etched glass coaster with a Celtic cross design in knotwork and lines. It is a clear jade glass 4" x 4" x 3/16" thick and polished edge. This is done as per most of my sandblasted designs in layers. Using that and carving, frosted, and shading techniques it creates a 3d effect as the viewer shifts angles of perspective.
