Gugolz Pitch

Gugolz is a time tested optical pitch that is a very viscous substance that appears solid, but can flow and change shape when heated and put under pressure. It is made from natural wood resins and does not contain any petrolium products. Long a favorite of amateur telescope makers for making pitch laps, it is used along with a polishing compound to polish a telescope mirror to a super smooth finish before being coated with a reflective metal coating.

We have Gugolz in varying grades of hardness (see the working temperatures for each version), each sold in 1/2 lb, 1 lb and 1kg units. If you need help selecting the correct pitch visit our help page: Selecting Optical Pitch.
