Interesting effects. I had accidently discovered that CMT 2050 blade and bit cleaner turned African mahogany a purplish color but it didn't go very deep. One swipe of a handplane and the coloration was gone. I wonder how deep this reaction goes. Steve
Not deep at all, I was able to sand the stain off without taking much material. I really liked how the different wood reacted to it. Cheers and thanks for watching!
Very cool! I think if you had sanded them back before adding the Rubio, you could increase the contrast dramatically. I’ve used that method with wood dye and it turned out amazingly.
Hi! The oil I used was Rubio Monocoat Oil Plus 2C. Here is a link to amazon: amzn.to/3uKmLR2 This is a multipurpose Hard wax Oil that penetrates while wet, then cures to a hard wax that can be buffed into a really nice hard and durable finish. There is a ton of videos and other oil/wax companies, just know that this type of oil compared to other oils is quite expensive in comparison. Cheers and good luck on your future project!!
Like the results on maple. I wonder if the heat would cause the veneer to delaminate? This would be my choice on some fiddleback maple veneered speaker cabinets. Just don't know if that heat would cause delamination between the wood and the substrate.
Pre-treatment with tannic acid solution will enhance the figure in acer species and darken the color depending on concentration of tannins. The iron nitrate stain was called aqua fortis (nitric acid's common name in 18th century & earlier) and as you note made with nitric acid and rusty wrought iron. Used commonly by American flintlock longrifle makers, historical and contemporary. The reddish tint doesn't always occur but is highly sought after by longrifle makers.
Being a chemical engineer who loves wood working, I love the experiment. Only questions I have is what 100% means--does 100% mean a saturated solution at 75degres or some other temperature? I also realize that Ferric nitrate is a strong oxidizer which reacts with the organics. Also I do not know if your localized heating get sections to boiling but literature indicates that can give off Nitric acid.
David, the 100% is just a term I used for the almost right ratio of ferric nitrate crystals and distilled water and was easier to stepdown for the 50% and 25% mixtures. I landed close to 30g per 2 cups of water, but there is room to refine for sure. My goal is when the heat releases the nitric acid, it reacts with the chatoyance of the curl and figure of the grain, while leaving the other grain structure untouched. I think this is achievable with different ways of applying, sanding, and reapplying. Over the course of next week, I'm taking notes and different applications to get the desired effect I'm looking for. Cheers!!

Very interesting stuff! I like the heat treatment method.
Thanks!
@@EricksonWoodworking you inspired me to start my own restoration business. I appreciate your channel.

Absolutely! I did some more testing and just a little bit of sanding and additional application, I was blown away by the result. Super cool stuff!
Can you name the penetrating oil? And how to work with that? Would that work for refinishing after stripping and sanding? Lovely

Do you sell this solution
Very soon! In about 3 weeks, I’m going to sell a kit on my website! Stay tuned…

Yeah it’s hard to say, sometimes it does take a lot of heat to start the reaction. Glue could unset
Which heat gun did you use? Thanks!
Hi! It’s a cheep heat gun I got from Ace hardware

Wonder if you could just pop it in an oven?
Jacob, not sure if that would work. With the heat gun, it did take an aggressive amount of concentrated heat to activate the reaction.
Ferreric nitrate ?
Nope.
