granite cut out from counter top - use it as a baking stone?
The topic says it all. I have a granite piece that would make a lovely baking stone. But:
-do they treat the surface other than polish it?
-will it explode or anything in the oven?
If anyone has any experience with it, this would be grand to know about. This piece has been hanging around for about 5 years, and I just found it again. It is almost useless for anything else. Measures 22"× 20", and 2" thick.
