Zinc Oxide for polishing stones.

Use zinc oxide as a finishing step of tumbling stones, after already going through polishing grits (80, 220, 400, 600). Zinc Oxide gives a lovely glossy lustre to your tumbled stones.

How to use:

In a 1.5/2lb barrel, mix 2 tbsp (level)

In a 3lb barrel, mix 3 tbsp (level)

In a 5lb barrel, mix 4 tbsp (level)

Tumble in clean water up to the top of the stones without grit for 7 days running to produce gleaming gems.

For best results: Make sure your tumbler barrel and end caps are completely clean - they should be totally free from grit and rock fragments to prevent leaks. It’s advisable to have a separate barrel per grit, as a few granules of a coarse grit in a fine grit tumbling stage could prevent your stones getting smoother, and could cause odd scratches.

Includes 100g.
