Baked brass
Need some input from someone with more knowledge than myself. I just rinsed about 600 brass casings after tumbling to make sure all the media dust was off, didn't do any research (foolishly) and tossed em in the oven at 300 for about an hour. They're nice and dry but have darkened a few shades, is this just oxidization/ tarnish or have I just baked a boatload of good brass into uselesness?
