Fumed oak destroyed once again

[antique1973]

Somebody got crazy with the sandpaper again. Heinous.

Sigh...this looks like the kind of hatchet job I would have done when I was a teenager. Mea Culpa!

That's a shame. A nice early Victrola XI with a rare finish ruined. I wonder if it can be saved?

It actually shouldn't be too hard to restore a fumed oak finish, if you have the workspace, and preferably, a container that will house the Victrola while you're fuming it. (I'd think a large cardboard box lined with plastic should work.)

This site provides pretty straightforward instructions:

Probably, the hardest part will be stripping off whatever new finish was applied prior to fuming the cabinet.

Here is a good one. Original finish not hardly worn at all. Note natural wear to upper corners where people would put their hands. Hand-written note stuck inside says "Weathered Oak" finish. Point is the VV-XI under discussion may not have a "fumed" oak finish at all. Once I got a real black VV-IX cheap because it was missing its motorboard. So I sanded down a replacement motorboard and fumed it in swimming pool strength ammonia, as strong as you can get without a license. But no effect. So I stained it with ebony and it matched perfectly. Another time I used "Black Walnut" Danish oil to replicate this "weathered oak" finish.

It would be real easy to restore the finish on the VV-XI under discussion. Problem is the seller's joke price. And when restored it would not be worth as much as an original, which would be $200.

OF, I am not sure that would work. I have built and fumed a fair amount of furniture. Oak is porous and the effects of the fuming penetrates quite deep (several mm). Sanding the surface would not remove the effects. I believe the real dark color was achieved with the type of shellac used.

Hi Brad:

I wondered about that too, after I posted the information about fuming an oak cabinet.

According to the information on Paul Edie's site, a top coat was normally not applied to fumed oak.


"Fumed Oak was produced by a process wherein the wood was placed in a tank of ammonia fumes for a period of time. This darkened the wood significantly, and brought out the grain texture in a way that increase the contasts. Colors can vary, but tend to be dominant in browns and tans rather than yellow or gold. There is quite a bit of dissention within the collector community in the identification of Fumed Oak, as some other finish options can produce a similar result. Note that the surface is not glossy; fumed oak finishes were usually waxed and not varnished. Fumed oak is sometimes called "pickled oak". The surface is slightly rough to the touch, but not "craggy"."

As you note, fuming penetrates the surface, so that adds credence to the theory that the Victrola in question--since the outside was stripped--was not fumed oak but another type dark oak finish.

Based on what the photos show, there is a definite shine to the wood. This could have been achieved by a high gloss paste wax, but I think, more likely, it might be shellac or varnish.

I would agree that Victor used some sort of colored stain/shellac/varnish to achieve the dark color.

The color that fuming produces is highly dependent on the tannin content of the wood. The picture below are of two pieces I made at different times. These were made with wood from different trees. I always try and insure that I use wood from the same tree on a piece to keep the color and tone consistent within the piece. Both pieces below were fumed for ~36 hours and are finished with orange shellac. As you can see, the color varies and neither are as dark.
