Are unglazed quarry tiles safe for use in an oven?

I have googled this question, but I seem to only get discussion boards and Amazon reviews saying "yes they are," "no they aren't." I'm hoping someone with some expertise in the hive mind can shed light.
Basically, I want a baking stone. At Amazon, the Old Stone Oven 4467 is $36, which is cheaper than at Sur La Table (of course). However, the idea of using a $1 "quarry tile" is appealing... if it's safe. Getting heavy metals poisoning over the course of a decade doesn't exactly seem worth the $30 savings.
How would I buy a quarry tile at, say, Lowe's? How do I know if it's food safe? Has any research been done on this topic? How do I prevent myself from buying a stone whose main ingredient is Reconstituted Stone Product, courtesy of 3M?
