Unique mold design creates openings in the casting. Fill casting molds with glass frit, scrap and powders to create one-of-a-kind cast glass pieces. The possibilities are endless, use to create personalized ornaments, suncatchers and pendants. Ceramic molds can be used many times. Coat with MR-97 or a casting mold release before use. Finished pieces measure 2" diameter. Dichroic project by artist Stephanie O'Toole, courtesy of Creative Paradise. Blue and clear project by artist Pam Peters.
