I have a question concerning Purple Heart. A co-worker who turns asked me why when he tries this with Purple Heart it “oxidizes”. I guess I was looking intelligent with a small piece of the wood in my hand. I have yet to work with it and have no idea what he is dealing with but knew I could ask all of you. Thanks for your help

Mike,
Purpleheart, when freshly machined is brown, similar to walnut. Over time with exposure to air (oxidation), it turns purple.
EDIT: I believe it's actually air and light that causes it to change colour.

To add to what Chris said, you have to be careful what finish you use. Do NOT use shellac! It will stay the chocolate brown and never turn purple. Oil/varnish or poly is fine. I'm not sure about lacquer, test first on a scrap if you want to use that.
