[QUOTE="GeorgeS, post: 1883998, member: 107925"] Simple answer: the cooling rate doesn't affect brass annealing. The reason quenching is a good idea is that the upper part of the brass case is hot. If you let it air cool slowly, conduction will bring that heat to the lower part of the case, which you don't want. So if you quench, that cools the neck and shoulder area quickly, stopping the heat from propagating down towards the head of the case and softening an area that shouldn't be softened. [/QUOTE]
