One pound angle cut ceramic media for cushioning rocks, and/or helping fill tumblers to 3/4 full. Approximate cylinder size of 5/16" x 9/16".
Ceramic media is used for cushioning rocks to prevent cracking & bruising, and also to fill up empty space and ensure a more even polishing in the barrel. Wash the media well after every stage, and it can be carried along with your rocks to the next stage (top up as needed). Great for both rotary & vibratory tumblers.
