Optical Lapping Pitch

Gugolz optical lapping pitch is offered in five grades from very soft to very hard, with melting points from 52°C to 87°C, and melts and pours without screening or mixing. This all-natural pitch is ideally suited for blocking, lapping, and polishing applications. Made from wood resin rather than petroleum byproducts, the pitch will not contaminate the polishing media or the substrate.
