Packing in charcoal for annealing provides an oxygen free environment to prevent scaling. There are other methods. It can be done in an inert gas oven and some people use a steel wrap especially made for this. I've tried the wrap and do not care for it. I have had things hardened in a gas furnace but never annealed. I always anneal and feel it is a very necessary part of the process.
