Some years ago I saw a post in another forum about the effect you can get by lime waxing(?) bowls. Searches have been unsuccessful, mainly because I probably was using the wrong search string. I just don't recall what the process is called. It gives the wood a green tint bringing out the grain in the wood. In this case it was Ash and it looked fantastic. Sorry I can't explain myself better. Hope this makes sense to someone.
