Men, I followed the alkanet root thread religously and have re-read it countless times. I'd like to clarify a few things with the two Englishmen, Salopian & Dig, as they appear to have "primary source" info from those retired stockmakers in the U.K.
Rose Pink seems to be sort of a mystery. I asked the infamous "Mad Monk", Bill Knight, about it & he said one would have to experiment making it from whiting & Brazilian logwood. For our English friends, Bill Knight is probably the foremost authority on black powder in the U.S. and is a chemist as well. Here's what he wrote to me about making "Rose Pink":
"The only way I can think of is that the whiting and logwood were ground in oil and then the oil applied to the stock. The whiting is not soluble in the oil and would break down if you heated the oil and added it. They may have used it like a grain filler. We see brown iron oxide pigment used as a grain filler/sealer on walnut wood these days. Watched that at the Martin Guitar factory above Allentown a few years back. And the commercial walnut gunstock fillers are the same thing. I have no idea as to what proportions of the whiting and logwood. You might have to experiment."
Dig & Salopian, is there any chance you could delve into this a little deeper as I'd like to experiment a little(?). By the way, I've read great things about the Chambers refinishing kit made in the U.K. Any opinions on it?
