Gugolz optical lapping (i.e., polishing) pitch is petroleum-free and made from all-natural wood resin. It helps maintain the purity of the polishing media and substrate, and comes in five hardness grades, ranging from very soft to very hard. The grades, whose melting points range from 52ºC to 87ºC, are fully compatible with each other, enabling users to achieve intermediate grades of hardness. The pitch is ready to use without screening, filtering or mixing in additives, and is suitable for blocking, lapping and polishing applications.
