Cleaning and Degreasing Animal Bones
Bone for tools, beads, needles and study must be free of flesh and fat: left in, the fat slowly seeps out, yellows the bone and smells. Simmer (do not boil hard) to loosen the tissue, scrape it off, then soak the bones in warm water with detergent, changing it until no more grease rises.
Beginner
