Howdy all,
One of the bits about getting into this hobby that I’ve really enjoyed is the chemistry. I have a bunch of chemicals in the basement that I’ve done bluing experiments with, wood finishing experiments, and now case hardening. I have read this thread with great interest. I have a KG or so of Sodium Ferrocyanate and plan to try some different combinations to see what seems to work best. There is an article posted in this thread from a metallurgist who suggests “ one part of potassium ferrocyanide, one part of sodium chloride, and one-half part of rosin, powdered and intimately mixed”
Sound reasonable. I might add - my Original plan was Sodium Ferrocyanate, charcoal, and borax. I figure borax was the bubbly part you see with OG Kasenit. However now I’m not sure since a rosin could give a similar appearance. Well I have powdered rosin from the violin varnish experiments so I’m going to use my ball mill setup to mix sodium Ferrocyanate, Sodium Chloride, air float charcoal, rosin, and borax. TI have a bunch of A36 I can mess with. Then I’ll see if it can case harden a bit and to take it a bit further, I have a 50# bucket of chert from Flint Ridge in Ohio and I’ll see if I can get it to throw sparks. If anyone has a combo they’d like to see let me know. It’s going to be rainy today so time to mess around with the alchemy stuff.0
