We have a need over here for a knowledgeable craftsman able to consistently get good British style colors with a hard surface and little to no warping. Proper color hardening and correct colors remains on my list of skills I hope to develop one day. It is an incredibly interesting subject and my first impression is that while based on science, a good bit of it is art, similar to browning damascus barrels.
If you have more details to share about the British process I'm all ears Ernie. I understand that most British Craftsmen use a higher percentage of wood charcoal than the average American color hardener.
