Decorative rock

What needs done to decorative rocks before adding to a crabitat? I was told to never boil rock. Just rinse them off?

What kind of rocks are they? If they are from a pet store or a craft store or a garden supply place they could be coated with epoxy which would be harmless but should never be exposed to high heat. If it's something from the backyard I'll either scrub it clean in the sink or pop it in boiling water for a few minutes- depends on how dirty the rock is and if it has any crevices for things to hide inside. They can destroy the bottom of pots while boiling, so use something old!

They're just rocks labeled "river rock" I found at the dollar store

What happens if epoxy is exposed to high heat?

[wodesorel]

It can release toxic chemicals, but we're talking 200 or more degrees before it gets to that point. Epoxy is a form of plastic, and anytime plastic gets overheated it will release toxic gases. Aquarium gravel is also coated in epoxy, which is why it should never be boiled either.
