This Emile Henry clay baking stone can be used to cook in the oven, on a charcoal grill, or on an open flame. It is oven-safe up to 500 degrees fahrenheit and highly resistant to thermal shock. The nonstick and scratch-resistant surface can be attributed to the food-safe, lead-free glaze that gives this product its sleek and shiny aesthetic. It is dishwasher safe and not recommended for stove top use. Made in France.
