What to use for post curing

You can also use a griddle set to 120. I'd put a piece of aluminum foil under it just in case but a piece of silicone under it will work too. Or if it's still in the mold, just put the mold on top of the griddle. Just be sure to not use the griddle for food afterwards. You can also put it near a heat source just not too close. You can also put it under a light that gives off a lot of heat (like a heat lamp set up).
