SilkeMat® is a non-carcinogenic refractory fiber blanket that can be easily cut, molded, rigidized, and shaped for use in kilns to slump glass. It can be utilized with or without rigidizing, and while applying a high-grade boron nitride separator like ZYP for glass firings is an option, it is not necessary. This product is free from "shot," ensuring most firings result in clean finishes, leaving only the fiber's texture on the glass. As a safe, non-carcinogenic material, SilkeMat can be handled and cut with ease. Once rigidized, it can also be cut or drilled to create pot molds, making it ideal for crafting unique fused glass masterpieces that will leave everyone in awe. MSDS Sheet
