Bruce, Charcoal bluing, could you please explain........ I really enjoy seeing you museum quality work!
Doug Turnbull is an expert on the "charcoal" or sometimes referred to as "Carbona" bluing. Its a trade secret for him and he will take it to the grave.
I have read in several places about the old process, they say its a hot (600 deg.) process that has charcoal and pine pitch melted and mixed and constantly drips on the parts as they rotate thus giving the parts an even dark blue color. I would like to learn to do it here but seems to be a lost formula. Anybody have info on it?
