POLISH POWDER FOR TUMBLING ~ CERIUM OXIDE ~ ALUMINIUM OXIDE ~ PUMICE POWDER

Choose from three popular lapidary / stone tumbling polishes.

In a standard rock / stone tumbling cycle which involves tumbling the stones in increasingly fine grits with a rotary or vibratory tumbling machine, the usual final stage is to polish the stones.

Cerium oxide is generally regarded as the premium polish option, ensuring the best results possible. It can also be used as a high-grade polish for removing scratches from glass and a range of other surfaces.

Aluminium oxide and pumice powder are more economical options and get good results. Aluminium oxide has been a popular polish for years but driven by environmental concerns associated with its disposal, pumice (which is a more inert substance) seems to be the new kid on the block, and increasingly popular.

Instructions for use:

Within the tumbler barrel, cover the stones with water by 1cm and add 1 level tablespoon of polish powder per 700 grams of stones to give a thin creamy consistency.
If the stones are producing a harsh and banging sound in the tumbler then you may need to add more polish powder to thicken the consistency, or alternatively add some plastic pellets to the tumbler. In all cases, try to avoid the chance of damage to the stones at this final stage.
Run the tumbler for 5-7 days, open and you should have gleaming polished stones.
