Thanks for adding to this, Brad. So you just went with mahogany and stained it with dark walnut stain? Looks great.

I dyed it black. It looks black and solid from afar. But you can see the grain up close.

Iron acetate will stain wood tannins to black. The more tannins in the wood, the better the effect. Birch won't take it well, and ends up looking more dirty than anything. Mahogany should blacken almost to the point of looking like ebony.

Make iron acetate by sticking a pad of fine steel wool into a glass jar of vinegar. Let it sit for a couple of days, until the steel wool has rusted/dissolved. Shake it up and paint it on. It's fun to experiment with different woods and types of applicators.

Cool idea!
I imagine that you'd want to make enough to cover everything in one pass.
Wondering if each new batch would be slightly different in color. ???

if it's all the same type of wood, it should all turn out the same. It's not a stain, but a chemical reaction with the wood.

I'd like to actually see that work. Is there a YouTube vid on it? I'll be there is. I'm gonna go and look.

I'll be back.

WOW! You can find ANYTHING on YouTube! Check out this video:

There are probably a dozen or so more videos showing how to do this too.

I'm going to experiment with it for sure. One concern is what kind of clear coat will be stable over it. Epoxy? CPES? Varnish? Automotive? Sand after or before? Certainly it needs to dry out, but beyond that, I wonder if there's any residual leeching. I also wonder how deep it goes. We shall see and report back. Thanks for the idea!

I've used it for pen making. It goes as deep as it soaks in, and being thin, that's easily 1/32". I've sanded afterwards, and not gone through the blackened layer.

One caution. The smell. I used it full strength on a mahogany pen, actually soaking the blank in it. The thing still smelled weeks later, even after leaving it outdoors for a while. Since then, I dilute it a little first, and that helps, but doesn't eliminate it. I haven't done much testing to see if anything neutralizes it or not. I doubt it would be an issue on a boat, but I suppose it's possible. Name the boat "Pickle" for laughs.

Pen finish is a mixture of shellac, linseed oil and bee's wax. It is designed to penetrate the wood to help preserve it. I have not had any problems with that finish or tung oil over the blackening. I have not tried anything else.

I do know this in advance: Vinegar is the enemy of all resins. If there is any vinegar residue, it will adversely affect resins around it or over it. Not sure about varnish.
