Baking or boiling is going to create some NASTY smell. Although anyhting that you do to cause them to re-cycle is going to let off some awful smell. It would be interesting to see what would happen to a piece of that rock if you soaked in in super saturated Kalk solution. Would it have the same effect (since the ph is 13 or so) as boiling/baking without the use of your household pots and pans?
You would have the same effect but there wouldn't be as bad a smell. You won't know what might precipitate though. I think saturated kalk is pH 12 so it's not immediately caustic to the touch but I wouldn't go soaking my hands in it.
It's basically an oven that heats and pressurizes for sterilization. Standard method to sterilize glassware in a biological/chemical lab. It's like a fancy pressure cooker.
