Ebonizing Wood

May 11, 2019The problem with this staining method is that it traditionally relies on the wood having enough tannic acid to react with the iron. This limits the wood choices and makes the results unpredictable. Oak is commonly used because of its high tannic acid content, and walnut is a very reliable wood for ebonizing.

Ebonizing Wood

The ebonizing process may raise the grain, especially if you use tea. It's a good idea to do a pre-ebonizing grain raise. Brush on a little water and, after the wood dries, sand off the whiskers. That should prevent you from having to sand the ebonized piece and taking the risk of sanding off the ebonizing.
