I want to make pizzas and hearth-type breads in my oven. Several recipes I've encountered call for the oven to be lined with unglazed quarry tiles. I've been to flooring stores and all the tiles are glazed and coated. I'm simply looking for terra cotta tiles. It can be one large tile, big enough for a 12-14 inch pizza, or a few smaller tiles that can be configured to whatever size I need for what I'm baking. Does anyone own these and if so, where did you find them? I live in Windsor, but I am frequently in the GTA. My cottage is in the north Kawarthas, so even a Peterborough suggestion would be helpful.
