jet black wood
Is it going to trash my trip wheel (ie; will it then be a dedicated wheel for the tanin only)?KurtHuhn wrote:Be sure you're not sanding too high before applying your tannin and iron acetate. Also, the best contrast seems to come from buffing off the surface black, not sanding. Black emery compound can be helpful in this regard. Tripoli is kind of slow. Sanding is a bit too aggressive.
Also - if i don't sand "too high", apply the finish, then trip the pipe, I will STILL need to sand the pipe to a high grit, the wheel isn't a good substitute for high grit sanding.
But thanks - I'll give it a go on the next one.

Yes, you probably want to dedicate a buffing wheel for this.kkendall wrote:Is it going to trash my trip wheel (ie; will it then be a dedicated wheel for the tanin only)?

And don't assume that you need to sand to a high grit after buffing the black off. I think you'll be surprised at the finish.
Another tip that you should keep in mind is that you really need to use good briar. If your briar has a reddish tone to it, that means it's still full of its natural tannins and won't show off the contrast. The whole thing will just go dark - which can be an interesting effect in itself.
hello,
does everybodys vinegar look like this?
i´ve achieved pretty good finishes but i´m still not happy.
is it normal that when the vinegarrust is applied and dried,
it forms black/blueish powderlike sh** on the pipe?
i tried sanding a little bit after applying the tannin, before applying the vinegar,
i found this worked a bit better/ made it easier.
i figured out that the mix forms somewhat sticky stuff, and i wouldn´t belive that it pentrates the briar well, when the sanding is done,
the vinegar can now affect better on the grains...
i must be doing something wrong.
how about mixing the tannin powder to alcohol instead of water?
anyone?

Re: jet black wood
I've been doing some research on this process and I came up with this google book on natural dyes. Specifically pg 40-42. It talks about both copper and iron. Unfortunately the photos do not show up.

I managed to get the same black effect with Tea. First attempt with strong brewed tea was so-so, it was mainly a grey. I then used a whole box of Black tea and boiled it down until it was gritty. This gave me enough tannin for the reaction with vinegar + iron. It turned black a few seconds after the application, black enough that no grain was visible. Buff and your good to go!

Re: jet black wood
Just a question. Has anybody found there is a shlef life to either their tannin or their ferric acetate? I dont use it very often on pipes but i when i was doing some experiementing the other day i found that the reaction was not as good as usually, yielding just a pale grey rather than the jet black i was getting a few months back.
Re: jet black wood
I'll get a photo up as soon as i remember to bring a camera to the shop! I just did a side by side test with tannin made for wine and my reduced black tea and I got the same result. The tannin seemed to dry faster then the tea. When I applied the iron vinegar the tannin turned jet black a few seconds before the vinegar on the tea. After it dried the tea actually seemed more black then the tannin before the buff. However, after buffing with brown trip they both looked identical. Black grain and tan briar. Both looked like Kurts photo on the first page. Both took stain the same.bikedoctor wrote:Hey Chris,
If you get a chance I would love to see a pic.
I have no idea on the shelf life.
