Bullseye Glass claims these are the best slumping molds they have ever found. They are imported from Creative Ceramics in Europe. The molds are slipcast from a specially formulated clay body, they have an exceptionally smooth surface, accept kilnwash uniformly, and do not crack under repeated usage if handled properly.13.3'' x 1'' (34 x 3 cm).
Note: The measurements given here are for the outer dimensions of the molds. This is to help you determine whether a given mold will fit in your kiln. Since they are handmade, individual molds will vary in size. Never cut glass to fit until you have measured your mold.
