I bought a slice of Bird's Eye maple as a plaque to mount a weather
instrument to hang on the wall. The slice has a birds eye maple
pattern on the face but it also has a beautiful bark pattern around
the edge perimeter. (lots of little points).

I would like to keep if fairly natural. Unfortunately I don't have a
scrap to practice with.

I'm thinking of linseed oil, tung oil or danish oil. I'm not
concerned about the face but how would these finishes do on the bark
section?

Any other suggestions?
