This tray mold provides a lovely area for a decorative rim contouring down 1/2 inch to a flat recessed middle area. The glass slumped into this mold will have a level bottom area and a raised contoured rim. Spectrum’s 6" x 12" fusible glass blanks work very nicely with this mold. As always, our glass molds have been sculpted specifically for kiln working glass and manufactured in the United States with our quality assurance. Glass separator required.
