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.

初学者

1 day, plus 1–2 weeks soaking

说明

Simmer

Cover the bones with water in a stockpot and keep it at a gentle simmer, not a rolling boil, which can crack bone, until the meat and gristle come away.
