Baking stone question
So, I've been hunting in my pantry for anything that may resemble a baking stone and I found I have a lot of these:
Has anyone experimented using glazed stone dinnerware in place of a baking stone? It does take well to microwave heating... not sure if its oven safe (I'm okay with sacrificing a plate or two to experiment but I want to be sure it won't damage my oven)
Also if I do get my hands on a tile (don't want to invest in a proper baking stone yet) what kind of thickness should I be looking for to be used in a gas oven?
