Hi, this is my first post at the pizzamaking.com forums. I have recently gotten into making pizzas, and I'd like some advice regarding pizza stones. I've read a lot about "unglazed quarry tiles" (including on this forum) being used as inexpensive pizza stones. I went to Home Depot recently, but there seems to be a lot of different types of items that fit the description of "unglazed quarry". So the tile has to be unglazed -- fine I get that, nothing shiny or brightly colored with patterns or paint-like finishes. But is there anything else I should worry about? My main concern is safety -- I don't want to slowly poison myself and my family over the next 20 years.
For example, I went to the gardening section and found loads of large (12"x12" and 16"x16") patio tiles, and they looked unglazed. However, they seem to made of concrete or cinderblock-like material, and gave off a lot of particles and dust when rubbed or handled. Doesn't seem very tasty to me. Would I be more likely to find a good pizza stone in the kitchen/bathroom tile section?
Is there a particular type of material I should be looking for? Clay, porcelain, terra cotta, etc. Again, my concern is safety.
Is there a particular brand of tile that people on this forum have used?
Also, does it matter whether I use a single large stone, or fit several smaller ones together?
Thanks. Looking forward to hearing from those more experienced.
