Just Used Unglazed Quarry Tile - but Not Natural Clay? Safe???
I have a question for anybody who knows much about Quarry Tile and its baking properties. I just got some unglazed quarry tile that was cut in small thin strips so it could fit perfectly on my gas grill. I planned to use this on my gas grill (which can reach 600F plus Temp) to cook pizza on. It was hard to find the tile, but I finally found a bunch of backordered quarry tile at a tile outlet that was extremely cheap. I just cooked 2 pizzas on my grill and it worked too good: the bottoms of both were completely burnt to a crisp. Even so, me and my family still ate both pizzas.
I'm posting this because after re examining the Unglazed Quarry Tile, I'm realizing that it may not be the safest tile to use. The tile was unglazed, and I told the associate who helped me that I was using it for cooking and he thought it'd be ok. The tile, however, is definitely not red clay. In fact the clay used is a brown - dark brown swirl resembling the pattern found on hardwood flooring. When I initially questioned the associate about this appearance, he assured me it was only the clay, but after eating both pizzas, I'm wondering if it was "natural" clay. I wanted to know if this is a health concern at all, or if this in fact is a natural or unnatural clay that is safe to cook with.
