venmarkint.wpengine.comA line of optical polishing pitch that comes in five hardness grades which are ideal for blocking, lapping, and polishing hard to soft optics is available from Meller Optics, Inc. of Providence, Rhode Island.

Gugolz Polishing Pitch is made from all-natural wood resin rather than petroleum byproducts and comes in five grades from very-soft to very-hard with melting points from 52°C to 87°C. Easy to use by slicing, melting, and pouring it onto a lap, the pitch carries abrasives well and presents them efficiently to the optic’s surface for a superior finish, claims the firm.

Suitable for carrying aluminum oxide, cerium oxide, and diamond slurries, Gugolz Polishing Pitch helps prevent contamination of the polishing media and optics because it is all natural. This pitch eliminates the need for screening, filtering, or mixing additives and all hardness grades are fully compatible and consistent to let users achieve their own grade of hardness.

Gugolz Polishing Pitch is priced at $29.00 per kg. container, with a four container minimum order. It is available online at
