[QUOTE="Coyote Shadow Tracker, post: 2716431, member: 116439"] Did you clean the brass before annealing? If there is any film/contamination on the brass it will come up with different colors. This looks like heated too much. In your "Brass Case" I think Yellow color is from Zinc. You may have Cooked your brass too hot and pulled the Zinc out of the brass. Brass is made out of 67% Copper & 33% Zinc. Cartridge Brass Cases have different % depending on the manufacture. Yellow is the color of Zink heated. Green is the color of Copper heated. You also saw a "Green" color in the flame so you were cooking the Cooper out. Thanks Len & Jill [/QUOTE]
