Had a bunch of rifle brass that got in the mud at the range. Took it home and washed it, dried it with an old towel and then placed it on a cookie sheet in the oven at 150. Wife came and put the oven to 425 to bake a pizza. The brass "cooked" at 425 for about 10 to 12 minutes before I caught it. (about time the pizza was done) It discolored the brass from bright yellow to a golden hue. Is it OK to load. Looks good just a darker color. Pizza was fine.
