Color case hardening
In response to a query in the electrical forum.
This comes up once in a while in Muzzleloading and firearms circles.

I couldn't find the notes and think they maybe be with a book I had lent and never got back.
The procedure I recall involved crushed cow hooves for the carbon content. As the name suggests the colour is a result but also the thin skin of hardness covering the surface of the treated part to a shallow part.
It applies to parts like lock side plates and flintlock frizzen faces. My black powder Pedersoli Tryon .54 cal roundball percussion rifle has colour case hardened, lock plate, butt plate and patch ball cover plate.

true color case hardening is a whole new world. you need a metal crucible, that has a tight air proof lid. bone meal, and a hot fire. it is involved. if not done right you wind up with warped parts or cracked,

Also talk of bone meal.Is that the same as our very own Oz blood and bone fertilizer?
I hope this assists.
