Made from natural wood resin, rather than petroleum byproducts, this line of optical polishing pitch comes in five grades from very-soft to very-hard with melting points from 52°C to 87°C. Allowing users to match pitch hardness to the optics being polished, this pitch is ideal for blocking, lapping, and polishing virtually any optical substrate material. Eliminating the need for screening, filtering, or mixing additives, Gugolz Polishing Pitch is ready to use by simply slicing the amount required, melting, and pouring onto the lap. This all-natural pitch is totally consistent from batch-to-batch in terms of hardness and consistency.
