If you don’t find what you’re looking for, contact us and we’ll make sure you get what you need.

If you’d like a bit of pumice for personal use—say for texturizing floor paint or growing a bonsai—you will find plenty of contextual, use-specific content to help you find the right grade for your particular application. We’ve built an extensive applications-specific directory to speed you to the right information.

FULFILLMENT CENTER. We have a dedicated fulfillment center backstopping the Pumice Store, so you’ll get your pumice in a timely manner.
