They were very difficult. I started with Mark Lee's, then went finally to Greeners formula with CuSO4 in it, using light torch heat in between to finally get colors.Did not use Ferric Chloride
wash.
This is my first post and I came here to get information on browning Damascus barrels such as these. They look gorgeous. I have a set from a Belgian percussion double that I'd like to see look even close to those. Can you give me additional info/links/instructions on the formulas you mentioned?
Thanks very much,
Tom
