I went to the Home Depot website and for instance, baking stones are like $25 each. I heard that some flooring tiles do the same job, though some of the types (like terracota) can expel some poisonous gases when heated; also, that I should avoid enameled tiles or anything with coating.Should I get a baking stone instead?Thank you.
Quarry tiles are genreally considered safe to bake on. The concern is with glazed tiles which may contain and may release lead in your oven - not a good thing! Unglazed quarry tiles are thick and are made of fired clay, basically as it comes from the ground. Thus it has other things in it besides clay. Ceramic tiles are generally thinner and but stronger. This is because they are made from refined clay in a powdered form. The end result is a more uniform tile, thus it is stronger.

Unglazed quarry tile is what is recommended for baking on. That's all you need to know. Don't use any other kind in the oven. You could look around for a cheaper baking stone. Try Wal-mart.
