Ever use iron nitrate on walnut?

Ever use iron nitrate (Aqua Fortis) on walnut? What happened? How about Tannic Acid? What to neutralize after?

Heat?

German walnut was often stained a deep red, is that what they used?

 

[Capt. Jas.]

I've used nitric acid on walnut with good success. I would not use anything fortified with iron though.

The iron turns walnut and cherry black.

Aqua Fortis seems to work on most species. It has an amazing affect even on beech:

That’s beautiful.

I only use it very light colored woods, works great on maple, love it on Birds Eye.

You tend to lose figure on the walnut cuts with iron nitrate.

I think you mean European walnut, as it has a red earthy tone to it.

Never heard of German walnut. French walnut is lighter, and somewhat resembles American walnut that is not too dark.

The iron turns walnut and cherry black.

If you really cut it back after the black, do you get the light wood back between the really contrasting dark grain runout? Might look good. I've never finished either with it.

I did mean European, ‘German’/ central European as Germany didn’t exist back in the time frames we deal with here, but diffent then the blonder French walnut. I do note those guns had a beautiful red tone, I don’t know how they got it or if it was just the color of the oiled wood.
Since the figure pops on these guns I always guessed a stain of some sort was used

Aqua Fortis (nitric acid) and iron nitrate are two completely different chemical substances.

Iron nitrate turns walnut ebony black. I don't know what nitric acid does to it.

just repaired a unmentionable for a friend. he fell during deer season and splintered the forearm.
i cut back the bad spot and added a black walnut nose cap. used aqua fortis. track of the wolfs product, being to lazy to make some. IanH understates it when saying ebony black. black black.

Nitric acids turns walnut a yellowish color, when dried in the air sometimes orange if certain applications are made, like adding some seedlac will bring out a yellow orange tone. .

Not sure what happens when heat is applied.

I know some people have tried to use nitric acid as a way of making black walnut appear to be English walnut.

Aqua fortis will turn all wood black eventually, some faster then others. You better figure on neutralizing it. But that doesn't always work for me.
Feric nitrate like Kibler sells turns wood varying shades of brown depending on the species and xensity of the wood and doesn't need neutralized.

That's the Kibler product I used on the beech stock in post #5. It's good stuff.

Yes. If you would have used aqua fortis it would be black.

Thanx; wasn't aware of diff until this thread.

I've only used aniline dyes on American walnut. I don't fill the grain either but I like the look.
