As I mentioned, lye reacts with the tannic acid in the wood to change the color. UV light is supposed to do the same, but I put cherry scales on a knife 5+ years ago, applied BLO, and it NEVER changed color or darkened. Conversely, I had a block of wood leftover from a stock that I experimented with. I applied the lye solution, kept brushing it on until I thought it was as dark as desired, and rinsed. When dry, it was noticeably lighter, so I did the other side, but left the lye solution dry on the wood. I put Minwax tung oil finish on it, and it is a beautiful dark red. I have no idea how long it would take UV light to turn cherry a darker, deep red, but lye can make it happen in a few hours; just the time it takes for the treated wood to dry.Does the lye just speed up the darkening process that cherry naturally does, or does it also make it darker than than just UV exposure will do?
Red Devil lye is commonly available at hardware stores as drain cleaner. I make soap so source it (sodium hydroxide) elsewhere in quantity.
Dave's approach is different in that he uses dyes to get the color he wants. Some old guns have red varnish on them, so there are differnt ways to achieve the desired result.
