Eric McHugh 23 Posted May 26, 2017 Share Posted May 26, 2017 (edited) Here is an essay I posted on my site about how I made a faux bog oak haft for one of my recent projects. I apologize for making you follow a link, but I don't have the time to copy it into a forum post with all of the images: Making Your Own Bog Oak Haft Edited May 26, 2017 by Eric McHugh 1 Link to post Share on other sites
Charles dP 474 Posted May 26, 2017 Share Posted May 26, 2017 Thank you for sharing this Eric. I wonder if you carved designs into the wood before the treatment if you would get deeper shades in the recesses due to pooling. Link to post Share on other sites

C Craft 177 Posted May 26, 2017 Share Posted May 26, 2017 (edited) After reading this I am intrigued! I knew a bee keeper that treated his homade bee hives and the frames with somthing similar to what they do pressure treating on wood so it is not as susceptible to rot. Something about using pressure treated lumber the bees would die off when exposed to it. He had his own mix of chemicals that did not effect the bees. He was also a welder and he built a tank from aluminum that he could put the pieces that he wanted to treat in this tank. It had a pressure seal and once all parts were in the tank he would pressurize with air and the pressure within the tank would force the chemicals into the wood. He said he could force the treatment thru a 1 x 4 but not all the way thru a 2 x 4, after 3 days! Any way just thinking out loud here! I know when trying to stabalize wood they do it by pulling a vacuum on the tank holding the materials to be stabalized! I now that works! Anyway once again just thinking out loud! Thanks for the info Eric. It has got the wheels turning in my head! Edited May 26, 2017 by C Craft Link to post Share on other sites
Alan Longmire 2,723 Posted May 26, 2017 Share Posted May 26, 2017 Very cool! I have done this using ferric nitrate and no additional tannins, and it makes a nice black on oak. You do have to use heat to completely catalize it, though. 1 Link to post Share on other sites

Did the ferric nitrate penetrate the wood deeper? On a slightly different note, the Quebracho bark powder instructions said that denatured alcohol could be used instead of water. I wonder if the tannic acid solution will go deeper with alcohol than water. I'm gonna have to try it. Link to post Share on other sites
Alan Longmire 2,723 Posted May 27, 2017 Share Posted May 27, 2017 No, it's about the same depth. Have you tried heat on your process? I use a propane torch with a flame spreader and get the wood just shy of scorching. Although, if you're going for jet black a little scorching can be a good thing! Link to post Share on other sites
Eric McHugh 23 Posted May 27, 2017 Author Share Posted May 27, 2017 No, I haven't tried the heat (yet) only because it seemed to work fine without it. I do have plans to try different techniques and heat was one of them. Much like the concentrated solutions speed up the reaction, I image heat would do assist in speeding up the solution too. Do you have a photo of the wood you darkened? I'd like to see the finished product just for reference. Link to post Share on other sites
D. Giagni 8 Posted May 27, 2017 Share Posted May 27, 2017 When I ebonize wood I use a similar process but, I think, a little simpler. First I make a pot of strong black tea. I wipe the wood with the tea and then use a heat gun to dry it till there is just a little moisture left. Next I apply the iron acetate (steel wool in vinegar) and let it sit for maybe 5-10 minutes and then use the heat gun again to dry it till there is just a little moisture left. Finally I wipe it down with the black tea again and let it dry naturally. After that I put the finishing coat of oil or whatever I'm going to use. Walnut and red oak turn jet black. 1 Link to post Share on other sites
Alan Longmire 2,723 Posted May 27, 2017 Share Posted May 27, 2017 Here you go. I was shooting for a not-totally-black on red oak. 1 Link to post Share on other sites
Eric McHugh 23 Posted May 27, 2017 Author Share Posted May 27, 2017 I think that is very attractive Alan. Nice work! I'm going to give the heat technique a shot. Link to post Share on other sites
grpaavola 30 Posted May 28, 2017 Share Posted May 28, 2017 Eric, Thank you so much for posting this! I have been trying to do this, and just about gave up because I was doing this in a vacuum. Again Thank you, Gabriel Link to post Share on other sites

Alan Longmire 2,723 Posted May 28, 2017 Share Posted May 28, 2017 Yep. I used to spend a lot of time living out of hotels and it gave me something to do in the evenings. 1 Link to post Share on other sites

Perfect way to scratch the metal working itch when you have to be quiet and fireless. That's why I own a hauberk. So as not to derail the thread, this is very interesting. My son wants an oak bastard sword, and tea staining might be the perfect way to class it up. 1 Link to post Share on other sites
