A line of petroleum-free optical lapping pitch that helps to maintain the purity of the polishing media and substrate is available from Meller Optics, Inc. Meller Gugolz optical lapping pitch is made from all-natural wood resin, which helps prevent contamination of the polishing media and substrates.

Ready to use without screening, filtering or mixing additives, Meller Gugolz optical lapping pitch is ideally suited for blocking, lapping and polishing applications. All five hardness grades are fully compatible, allowing users to achieve any intermediate grade of hardness.
