MORE ON THE WAY… updated Feb 1st. Call the store to see if available in-store. The Wizard makes this flame-ware clay in house. It is made to withstand high temperatures and can be used in the oven, smoker, stove-top and on the GRILL! We call it a “pizza stone” but this size also works remarkably well for finger foods such as french fries. Measures approx. 15″. These are very sturdy stones made to last a lifetime, unless you drop it in just the right way, of course. We have other shapes and sizes in our store. Email us for details.
