Good to see the interest in this subject.
Here in England good guys are passing away very rapidly, and the knowledge is dying with them.
Perhaps some guidance on making rusting liquids , specific tried and tested or modified solutions from Angier's book? Remember with import restrictions and taxes we may not be able to easily obtain American brands such as Laurel Mountain etc.
Tips and pitfalls would also be useful. Move the whole thread to Gunsmithing if necessary (admin?) But lets us share our knowledge please.
From Angier, I like to use a C.10 variant for Damascus and Twist. C.19 is what I use for Fluid Steel. It's a very deep black. I've also used an Aqua Regia type for Fluid Steel, (HCL and Nitric acids, iron filings/powder) but it doesn't keep for long periods like C.19 does.
Regards
