CAUTION: Some of these materials are toxic in their dry unfired or fired state. You should always use a dust mask when working with these materials. We have an inexpensive Toxic Dust Mask available. Also, Material Safety Data Sheets are available, for any material you've purchased from us. These materials have always been potentially harmful, so let’s get serious about safe handling.

SHIPPING and PRICE CHANGES: Some raw materials are relatively inexpensive, but are heavy. In some cases shipping may cost more than the product ordered. When the cost of the material ordered is equal to or less than the amount of the shipping, there may be a delay to confirm that you still want your order shipped. Some of the minerals will be noted "Subject to Change". If our price increases after an order is placed, you'll be contacted to confirm that you still want it, at the higher price.

Orders may be placed online or via email to be picked up in-store. These must be placed 24 hours in advance of pick-up and can be picked up after 1 pm on the following business day. Without the 24 hour notice, you'll have only the option of purchasing whatever size bags are currently on the shelf; we won't be able to break down bags while you wait. No exceptions will be made. Please see our shipping policy on our store info page.
