Holiday Gift #2: Ebonized Oak Serving Tray - Finishing

Just wanted to add a little bit to the last post.  Ebonizing of the project went well.  For the iron solution I used steel wool and apple cider vinegar.  Time pressures made it so I couldn't wait 7 days for the solution, so I waited about 4 days, stirring each day.  And since it was chilly in the garage I also wrapped it in a heated "corn cozy" a lot of the time - heat increases the rate of a chemical reaction.

The steel wool had not disintegrated like it usually does, so I was a little worried.  So I tested the solution by dipping a couple test pieces in an oak-shaving tannin broth and then in the iron solution.
Test pieces turned color quickly
With a good test I went for it, giving the project a heavy coat of hot tannin broth, letting it dry and later knocking down the raised fibers.  I repeated that and after it was dried and sanded I applied the iron solution.  The color went dark quickly, but I still added a couple more coats.

When satisfied, I coated with BLO, waited 15 minutes and wiped dry, then waited a day before a second coat.  Lacking time, that was all the coats it would get.  This morning I gave it a couple coats of paste wax and it shined up pretty good.

Happy with how this came out.  And just in time ...

  1. Color looks good Matt. I didn't wait 7 days for either of my SW&Vs to cook. As soon as it was black I went with it. The heat idea is one I'll try and maybe I cut it down a day.

    1. Thanks Ralph. I was surprised at how well it did considering that the steel wool still seemed mostly intact. I'm sure there's more iron in the vinegar solution than I realized.

      Merry Christmas to you and yours.

    1. Thanks Bob. Hopefully you'll like the ebonizing. It's a really interesting look and you can still plainly see the wood grain.

      BTW, in a week or so I'll be posting about a couple old planes I bought locally off Craigslist. Probably won't cover the history as well as you do, but I hope it will still be interesting.

  3. Cool, that should be interesting, looking forward to these posts.
    To me half the fun with these old tools is to research them, you never know what you are gonna find... And then it send you in another directions and now you need to find a XYZ... :-)
