I've heard that baking rocks is a very bad idea. The rock may have formed with an air pocket inside and if you bake it, it could explode- ruining your oven. I'm not sure about bricks- if they've been kiln-fired, they should be ok to bake, but you risk them cracking. When I've needed rocks sanitized, I've boiled them for about 20 minutes. And if you need to get rid of any calcium deposits, you can add lemon juice to the hot water as a pre-rinse.
