I have a good friend that has reestablished colors on perhaps 20 double guns at his home workshop using bone charcoal pack, quenching in highly oxygenated water after heating to around 650 degrees in his heat treating oven. His colors are very nice and do not look cheap or tacky. They may lack some of the colors that are possible to achieve at the 1200+ degree range. My question is, can variation of the pack materials help achieve some of those colors at low temps that are normally brought out at the higher temps, or is it only possible to get those colors by going to the higher temps? If so, why risk the higher temps if polishing or chasing of engraving is absolutely not necessary?
