So I used the candle method on 15 pieces today. The thing I noticed, is once I wiped off the soot, there was no visible signs that the brass has been annealed. While looking on youtube, I saw several demonstrations of guys doing it with torches and I noticed the neck turned and seemed to stay blue. Is this something I would expect with the candle method, or does the higher, quicker heat of the propane torch cause the blue and I should not expect it?
