[QUOTE="LoneTraveler, post: 1024471, member: 77249"] Case hardening is just that, The adding of carbon to the outside of low carbon steel will allow a person to harden a thin layer of the outside of a piece of mild steel allowing it to take a wear film, but still not be hard or tempered clear through like High carbon steel. In playing around blacksmith shops in my youth I seen a lot of things used in casehardening, Harness leather or old leather belting was cut into shreds and packed in layers with bone meal or broken up bones around a part in a vessel to get some of the multi colored case hardening. Pottacium cyanide a deadly chemical will case harden with a even color. Years ago in repairing old original muzzle loader locks for a pharmacist friend, he gave me a baby food jar full to work on his guns and keep them original looking. It was in a white powder form, Heat part red hot, dip in the powder, it melted and coated the part. Reheat red hot and quench in oil or water and it gave a great hard skin on the part. There used to be a product called Case-Net or Case-Nit that was used for case hardening, We had it in a machine shop I once worked in. It was a heat red hot, dip, heat red hot again and quench without the poison danger. [/QUOTE]
