The Mineral B Crepe/Tortilla Pan is made of carbon steel - 99% iron and 1% carbon, the most natural cooking material praised by Chefs around the world. Lighter than cast iron and more heat conductive than stainless steel, this 9.5" Crepe/Tortilla pan becomes naturally non-stick after seasoning, without any chemicals or synthetic coating, and gets better the more you use it. Use it to spice up your quesadillas.
