10x10 Square Dam Mold - Fusible Glass Frit Forming Mold Mold measures approx. 10" x 10" x .75". To use, simply pretreat the mold with kiln wash or nitride spray, and remember to ALWAYS ELEVATE THIS MOLD OFF THE KILN SHELF USING KILN POSTS to avoid mold breakage (see 3rd and 4th photos. Frit and kiln posts are not included). This dam mold is a fantastic new concept in frit forming molds! Simply fill the mold with frit, crushed glass, frit balls, stringer...basically whatever you can dream up....and fire to a full fuse. When the design comes out of the kiln, simply slump into your favorite fusible glass mold or just display as is! No kiln dams required. Yay! The end result is perfect edges every time with no cold working required! Our sample shows approx. 1,088 grams of Bullseye Glass Frit filling the mold. Remember that the glass will shrink considerably once full fused. Our finished square sheet was approx. 6mm thick using that amount of frit.
