I'll restate my question now that I see hardening sounds pretty straight forward (whenever I do end up trying to make something out of it): Can A2 be annealed in Vermiculite, or does it have to be done in a furnace? Being even more specific, will Vermiculite limit the cooling to the "40 degrees F per hour or less" rate that is called for when annealing A2?
Thanks again
I was referring to his revised question.
