Thrud, in another posting (CRS vs HRS) mentioned color case hardening. I just got MBR1&2 from Guy Lautard and read his description and recipe.
I'm wondering if Thrud uses that recipe, or Kasenit, or what? Does the Kasenit process produce good coloring? I haven't done any of that (intentionally that is).
Also, is the coloring effect highly dependent on the type of steel used?
