Johan! Thank you very much for this video :-) Very informative. I got into leather working as a result of being a custom knifemaker. I didn't want to offer my knives for sale without sheaths and I had a bad experience with a leather-working friend of mine. I offered to pay him to make a sheath for one of my hand forged knives. He had my knife (27 hours a labor) for over a year and never made the sheath. When I finally got my knife back it was covered in rust and the Carbonia blueing was ruined. From that point I resolved to learn leather working and make my own sheaths. Thank you for helping me on my journey :-)
Thanks I did not know how it would work on leather. I have used the same method for aging wood. Apply to bare wood frame throw on a little dirt, wave a propane torch over it to dry it, and wipe off. Made a old looking frame for my leather carved picture.
What do you suggest for using as a finish coat over this? This is a really good even black. Does it leave a vinegar after smell? Thanks for the informative videos. Very useful and interesting.
Kerry G + Hi Kerry, No vinegar smell after an hour or so (I would stick to white vinegar only - no sugars and things like in Cider vinegar). Any finish coat will do. Remember you have just changed the color of the leather fibers - nothing more. I use something like Dubbin or oil or a conditioner on a working leather; and something like supersheen if I want more of a shiny look to it. [Usally I let the dye dictate what I use over it: over a waterbased dye, only an acrylic sealer so that the dye does not wash off.Over a Pro Stain, I prefer the Pro Conditioner of Pro cream.]
Johan, a couple questions please. Can you dilute the vinagroon so it's lighter, and can you put other things with vinegar to get different colors. Thank you.
I have not tried diluting it, but it sounds like it would work : dilute with either water or vinegar. And test it first..... No, adding anything else will bit work - his is a chemical reaction and will always make black. In stead of the vinagroon, you can use a solution of potassium permanganate to give a brown oxidation.
Nicho Vermaak, the supersheen is from Tandy (I live in the US). There is a Facebook group for South African leatherworkers and they will be able to tell you where to find it or what alternative is available to you....
Patrick, no, the leather needs to stay acid. If the pH goes too far above 4, the leather will start to de-tan.... You can see more at www.johan-potgieter.com/ll/?p=148
@Michael Wolff Do NOT neutralise with baking soda!!! It is really bad for the leather fibers that should stay acidic - just rinse with clear water. There is a longer description on my blog post: www.johan-potgieter.com/ll/vinagroon/
Hi Johan, I used a plain white Vinegar and the smell is awful for days, it improves with a coat of Super-shene or Resolene, the results are more than fantastic , but I must say I am at a loss for what to do about the smell (I have tried balancing the PH a little by dunking the leather into a solution of water and Bicarbonate of Soda/Baking Powder) Any ideas Sir
I think the "washing" with water is a good idea, but it is a bad idea to add baking soda - the leather will not damage if it is acid - around pH 4 - but it will damage at a base acidity (above 7). As for the smell, one thing that comes to mind: If the article is such that you use a fat based conditioner such as Dubbin or Dr Jackson's Hide Rejuvenator, you can always add a drop or two of the aromatic oils people use for health purposes. I confess, when it comes to a water based sealer like supersheen, I do not have a better solution than time.... I'll ask some of the online groups if anybody has a suggestion. (Johan here - I am using my mom's computer.)
Thanks Johan. I do use Olive oil, or a mix of Beeswax and Coconut oil as a restorer, and that helps (well it lessens the smell a little). I will try your suggestions and see what occurs :) Great videos by the way, I have only been working leather for about 6 months, and they have really helped me improve Thanks again!
@@Mariepotgieter ///I think the "washing" with water is a good idea, but it is a bad idea to add baking soda/// Remember, you are not raising the pH above 7, it's already well below that because of the vinegar and tanning ...adding bicarb is bringing the pH back towards neutral. It's a good idea to use bicarb to neutralise the leather if it is going to contact anything made of carbon steel ...like a knife sheath. If the acidic sheath were to get wet, then acidic moisture could transfer onto the knife blade and rust it. When I've used vinegaroon, I've washed the leather in bicarb solution, then again in plain water, dry slowly and add some conditioner before the leather gets too dry. Works well.

Hey, I never heard of this before now. I used this product on a piece for my brother. It came out with a good dark black. Best ever! Thanks!

Great. Very Informative
Thank you for 6:36 . When you filled in those two areas I smiled.

Muito bom 🇧🇷

Thanks for the wonderful videos. Learnt so much since I started watching. May I ask where you obtain the Super Sheen mentioned in this video?

Baie dankie dat jy die tyd geneem het om my navraag te beantwoord. Sal jou raad volg. Beste wense.
As vinegar is a mild acid, should you use a baking soda bath to stop further acid erosion of your leather over time?
Patrick, no, the leather needs to stay acid. If the pH goes too far above 4, the leather will start to de-tan....

I wonder if a spray bottle would be useful.
