Oak bowl

 

I turned this bowl in green oak a few months ago, and today I put it back on the lathe to fuck it up by gouging a bunch of chips out of the inside with a scraper catch. Hey-ho.

I ebonized it with ferric acetate, and it really shows the difference in tannin levels between the sap and heart wood. The heart goes really dark, while the sap is affected to a much lower degree.
