We recommend Pumice Powder for hobby tumbling. Our special grade works fast with excellent results. It’s cleaner, lighter and more cost effective. ‘Tin Oxide’ can also be used for that extra shine, and ‘Zinc Oxide’ can be used as a lower grade polish. Cerium Oxide is used for the best results and greatest shine, and goes the furthest, but is the most expensive. All our polishing powders of quantities up to 10kg come with a resealable container, whilst higher quantities are shipped as sacks. You can also add plastic pellets, making it go further and polish faster. Weights are an approximate Gross value.
