Ol' Recipe Maple Finish

⚙️ EPISODE #197: Have you ever wondered how those old long rifles got such a beautiful rich finish on their gunstocks? Many were dyed with and old recipe using Iron Nitrate to produce a chemical reaction stain bringing out the max figure and pop, as well as a warm and rich brown color. I’ve been experimenting with this finish lately and in this episode I share the almost magical process to create this beautiful stain. Check it out -- it's pretty cool!

I actually make my own solution of iron acitate (virtually the same effect as what your doing) by puting some 4/0 steel wool in a jar of white vinegar and letting it sit for a few days. The vinegar oxidizes the steel wool. And for a tannen pretreatment try black tea, it works especially good on pine.

Tom, Fantastic Vid. Sorry I missed the Live but I did learn so much here. Great presentation and of course as always, thorough. Thanks!

Great class
Traveling Thursday night just now had time to watch.
Thanks

Alas! Sorry I was not available for the "Live Session". However, I am very grateful that I can catch the replay. The finish I was referring to in a previous SNL was iron acetate or ferrous acetate, which is used to ebonize wood according to the tannin content of the material. I use it a lot on walnut to make a "faux ebony" for finials used on turned boxes. The iron nitrate / heat gun recipe you provided on this video showed a stunning result. 😍 I love wood finishing and look forward to trying it out. Thank you for sharing your knowledge with us. 😊

Maple is often my choice for hardwoods and I loved the guitar video you made with the dyes but ugh so much hassle - I am absolutely gonna try this, thanks so much

[@joshwalker5605]

This is just spectacular, wow

[@kevingade5615]

[@Johnsmith-fr9qd]

FYI here is what National library of medicine says about Potassium Dichromate: "Potassium dichromate primarily affects the respiratory tract causing ulcerations, shortness of breath, bronchitis, pneumonia and asthma but can also affect the gastrointestinal tract, liver, kidneys and immune system. This substance is a known human carcinogen and is associated with an increased risk of developing lung cancer and cancer of the sinonasal cavity."
If I were you, I would use a respiratory mask and would not use it on anything that is in contact with food.

[@EpicWoodworking]

Thank you. Yes, I tried to impress strongly to follow the safety recommendations. The main danger is from breathing the dust form, with any risk of breathing greatly reduced when in liquid form. Definitely worth being cautious when using it. Thanks again! 👍

Since the mineral oil is non-drying, will it diffuse into the wood and the grain pop effect fade?

[@dpmeyer4867]

thanks

On the link provided for Wood Finishes Enterprises, I can only find Ferrous Sulfate in granular form. Would that produce similar results to the Iron Nitrate solution you show in your video?

[@briggstim1]

How would this react with curly Sapele?

[@williamkey855]

Wonder what this would do to birds Eye maple? Any thoughts on how to make the eyes pop more? Bill K

[@michaelcima5772]

Yep ferric nitrate to ferric oxide is correct

[@michaelcima5772]

Ferrous nitrate and ferric nitrate are not the same. Ferrous is iron 2 oxidation state and ferric is iron 3 oxidation state. One can oxidize the ferrous form to the ferric form.

Not sure what happened but the audio does not seem to align with the video.

[@joshwalker5605]

Ok for me
