[Source] Small amount of glacial acetic Acid


#1

I am looking for a source for a small amount of Glacial Acetic Acid,
perhaps 4 ounces, to use with patina recipes. So far the smallest
volume I’ve found online is a pint.

Any ideas?

Glacial Acetic Acid is a fancy name for concentrated vinegar, so take
regular vinegar and reduce it. Regular vinegar is 5% concentrated, so
if you take 80 once and reduced to 4, you will have what you looking
for. That said, considering all the work and resulting smell, I would
opt for purchasing a pint.

How do you propose to reduce vinegar The boiling point if acetic acid
is below that of water.

You will have to use distillation set up.

Leonid,

Ya must be kidding :slight_smile:

Back when playing with B & W film (dating myself) I used to buy it
over the counter at local photo type stores for a few bucks.

Pretty good for a cheap stop bath when diluted, these days probably
a hazmat shipping charge but one of the most gentile acids a jeweller
might use.

Some nasty chemicals are a normal part of jewellery work, attempting
to make them at home scares me. Learn to use them and just pay the
price of hazmat and being included on watch lists :slight_smile:

Hard core old school jeweller offering advice and I’m still alive.

I agree with you. It does not pay to fuss with making your own. But,
in case commercial stuff is not available, I simply offered an
alternative.

Maybe, compared to some, but make no mistake, glacial acetic acid is
nothing to be casual with. Capable of causing really serious burns.
It might not be as bad as some of the strong acids but it’s still
dangerous stuff. Treat accordingly.

I do know how to use chemicals safely, having earned degrees in
Biochemistry long ago. I may still find HOAc locally at a photography
supply shop; need to make some calls tomorrow. The HazMat charges are
so much more than the simple product. I’m experimenting with some old
patina recipes. Meanwhile having lots of fun with liver of sulfur and
various metals, concentrations, durations, temperatures.

If no local source, there is Duda Diesel.

Thanks to all for the various suggestions. C
