Vinegaroon tutorial

[scooby]

There has been some discussion regarding colouring leather using vinagaroon in the past so here is how I make and use it.

Note! - I am certainly no authority on this - It is just how I do it!

MAKING VINEGAROON

'Ingredients' – Steel wool & Distilled Vinegar

This batch was made using an old brillo pad which was washed till no soap remained then left to rust in a jar.

To speed the rusting along I rinse the wool with a little water then pour out the excess to keep it damp for a few days.

Fill up your jar with the wool in it with distilled vinegar (this is Tesco value brand!)

And give it a good shake – it will look like brown muddy sludge – NOTE – ensure you loosen off the lid aftwards! (it will produce gas and build up pressure while 'brewing' and it can explode if you leave the lid firmly on.

After a few days it will look like this – you can see the bubbles still being produced!

Lock the lid back on and give it another good shake before loosening off and leaving for another couple of days – repeat this for about a week till the wool is dissolved away.

It will probably still be cloudy sludge looking so I filter through a piece of kitchen paper to take out the big bits

Once filtered it should look a little like weak back tea – ENSURE you label it well!

You can use it straight away but I have found it better to leave it a couple of days to 'mature' – it kinda clears and looks more like a liquid rather than a solution if that makes sense.

USING VINEGAROON

It's simple - really simple! Either dip your veg tanned leather into the solution or daub / brush it on. It starts to darken almost immediately. You may have to do 2 or 3 applications to get the colour you want although it does darken and look better once it is oiled or waxed (I use mink oil)

To neutralize the acid I soak a couple of times in a strong bicarbonate of soda solution then finally rinse in clean water.

Here is a before shot of my demo piece of leather beside a white sheet of paper

A link to a(poor and out of focus) video of the process to show the speed of the change

And finally a pic of the result (before neutralizing and oiling!)

Please note this is not a dye - it changes the structure of the leather itself so it will not wear off - however I find it gives a more even effect and is very quick and cheap!

FINALLY..... ONE I MADE EARLIER!

great tutorial scooby. The pix make it easier to follow. Thanks so much!

Couldn't have said it better Scooby! Great Tutorial! That's almost exactly how I make mine. The only thing I do differently is use new 4x steel wool. I don't want traces of soap in my mixture. Other than that, exactly the same! And after, I rub mine with neatsfoot oil!

On a lot of the recent posts re: vinegaroon I've seen this about rusting the iron first and I'm curious as to why? While I have used old rusty iron at times, I normally use new iron/steel (mostly scraps from my knifemaking or de-greased steel wool ) and it works just fine - the whole process is after all to have the iron dissolved by the acetic acid in the vinegar to produce ferric acetate - which by the way can be purchased in crystal form from science supply companys, if you don't want to fuss with making the mixture...

I don't claim to be an expert, but I have been using this process for staining leather (as well as woods such as curly maple) for 35+ years and have never intentionally pre-rusted the iron????

FWIW - here's an original recipe from 1875:

VINEGAR BLACK (aka Vinegaroon)

For giving color to the grain of leather there is no blacking that will at all compare with the well known vinegar black. This may be made in various ways. The simplest, and, without doubt, the best, is to procure shavings from an iron turner and cover them with pure cider vinegar; heat up and set aside for a week or two, then heat again and set in a cool place for two weeks; pour off the vinegar, allow it to stand for a few days, and draw off and cork up in bottles. This will keep for a long time, and, while producing a deep black on leather, will not stain the hands.

Note no rusting mentioned.......heating speeds the process some what, but is not absolutley necessary.......

As for changing the structure of the leather - not exactly - vinegar black is what is technically known as a chemical re-agent - the ferric acetate reacts with the tannins in the leather to produce the black color - in fact washing the leather with a strong black tea or coffe solution will speed/enhance teh blac color - this can be done first or after applying the vinegar black.....

And sorry I DO NOT mean this to sound negative at all - the tutorial is otherwise a very good one, but I have been meaning to ask "why"? especially since pre-rusting may possibly be counterproductive since by doing so you have changed the nature of the iron from the blue/black stage to the red/brown stage

As always others mileage will vary.......

PS - I've got a gunrig I just finished with vinegaroon made from new iron and as soon as I get picks I'll post them.....

Thanks for the comments Chuck and i'm not in the least offended - after all i'm just a newbee to this game after all!

I have no idea about the rustyness - i read that is what it should be like so that is what I have always done.....

also I understand re 'changing the leather' its just that It was the best way I could think of to describe the fact it isn't a stain to people

to be honest I wondered re rusting too - i'll try a batch without somewhen and see if there is a differance.

I think the reference to "rusty" metal may have come from the requirement to use "rustable" metal...simply the need for an oxidizable iron based metal.

...which reminds me (and I don't remember which thread to look in) but didn't someone say they were going to try copper and aluminum and post results?

I remember that walnuts were used to make a pretty nice brown, but I'm not sure about the other colors.

Oh and if you use "too much" metal in the jar, you'll end up with some pitiful looking scraps in the bottom and your vinegaroon will be almost chemically neutral. I say almost because after several weeks, the acetic acid had stopped reacting with the metal and direct exposure to baking soda produced NO REACTION. So, rinse well with warm tap water and wet mold.

I've used Chuck's method of making vinegaroon for a couple years, now. I clean the steel wool with lighter fluid then shake out most of it and burn off the excess. When it's cool enough to touch I put it in the vinegar. One of those big 0000 pads in a quart of vinegar works great. I never strain it or anything. I suppose I should but it never occurred to me. I can get a beautiful rich black in a couple of days with a new batch.

Here's a picture of a holster done with it. Oops. Wrong pic. Here's the right one.

Thanks for the great post. i can't wait to make some of this and try it out. The results from your photos look amazing.

I just made a batch of this stuff and tried it out! Vinegaroon is MAGICAL STUFF!!! So cool to watch the leather change colors!

I do have a couple of questions though. What is the average shelf life of this mixture? Does it seperate over time? Can it be kept in a glass container for extended periods of time?

Also, a solution of bicarbonate was mentioned....what is that? What would this be necessary for?

[MarshalWill]

I keep mine in mason jars. I never really tighten the tops but I suppose I could. The stuff gives a nice, rich black for over a year. I have some that's a couple of years old. It produces a medium grey which is fine as a base for a nice dark brown color. I can rejuvenate it but it's nice to have the grey so I just make more when needed. Yeah, it is magical. I don't use black dye anymore unless it's with leather that doesn't take the color.
