I used vinegar after soaking steel wool in it and it created a nice
color on a little oak bowl now used for wrapped candy. Has anybody
heard of any health problems from ebonizing an oak bowl using vinegar
and steel wool, covering the bowl with mineral oil and then using the
bowl for eating salad? When I searched this site using 'ebonizing' I
was not able to find discussions about health concerns with vinegar
and steel wool. Thanks.
