The Walmart write up in the title says ceramic..
"Astercook 20 Piece Ceramic Pots and Pans Set Non Stick, Cookware Set with Detachable Handle, Oven Safe, Induction Ready, Stack-able RV Kitchen Cooking Set Removable Handles, Cream White."
The box it came in says Granite. No where in the packaging does the word Ceramic ever appear. In the text of the item on the Walmart store it says "Pan material: Aluminum, Ceramic, Granite." So something is off somewhere. I'm not returning them as I am happy with the price and the quality of the product, plus I have used one of the pans and it worked very nicely so there is that.
