So I have been turning some very wet ambrosia maple and have a puzzler for you chemists and other smart people. Why do blotches of purple appear within seconds of turning it? I'm not talking about the smudgy grey/black moldy look that you find the next morning sometimes when restarting an unfinished turning. This appears suddenly just like the old iodine solution on the potato test for starch. A very dark almost black purple appears where the chuck jaws have bitten into the tenon.
I suspect it is a chemical reaction with something on the turning tools and on the chuck.
Anyone see this? Cure?
