I am in the process of of building a clay oven and would like some input.... I have a large piece of white marble I have scavenged and would like to use for the floor in the oven. Seemd like it would be a great surface to cook on but I am unsure about the thermal characteristics of marble for this use. I am aware of the potential of certain rocks to explode when heated but I have seen stone used in ovens to cook pizza on. Anyone have any thoughts?
