what's glycerin for?

updated tue 15 oct 02

 

John Jensen on fri 11 oct 02


What might be some uses for glycerin in a pottery. I think it can be
used as a skin moistener, but what else? I have come across a few
bottles of it and am not sure what to use it for.

It can be used as a brushing agent for glazes or over glaze decorating
colors. I use it in stain mixes for painting over majolica.

John, you can use it to add to underglazes and engobes to ensure smooth
brushing...

a modicum of Glycerin added to an underglaze or onglaze pigment can make banding and brushwork smoother and finer. The gylcerin just burns out with no ill effect that I ever saw.

I did hundreds of dinner plates and salad plates for the Casa Mexico Restaurant in Cambridge some years ago and the glycerin in the (onglaze) iron oxide and cobalt stains made for a very smooth banding and sumi brush leaf decoration thereon.

Add it to engobes to make them more brushable.

You can use it in clay 500 ml to 500lbs of dry clay. Makes the clay more
plastic. I have been doing it for about ten years.

Tom's E-mail on sat 12 oct 02


With all this discussion about glycerin, I decided to stop at my local drug
store and buy some; I found some in the cosmetic section - rose water and
glycerin and a small bottle [few ounces] in a separate bottle for about
$1.70; am I looking at the right stuff?
Tom Sawyer
tsawyer@cfl.rr.com

Lily Krakowski on sat 12 oct 02


Yes. I use it in some slips. Even glazes. Be advised: as I no longer can
hold larger pots well enough to pour glaze, I put glaze on with a brush,
preferably while the pot is leather hard. Glycerin just makes the brushing
nicer. By the way; NASCO is the only clay/art materials supplier I yet have
found who sells glycerin in bigger bottles. Does anyone have a source for
BIG bottles? Like a gallon jug...

Dear John Jensen,

Opened a bottle today to make a medium for mixing prototype glaze =
formulations.

Made a 20% solution with rain water.

Allowed my samples to soak overnight before mixing. It assists in =
getting good flow from the synthetic flat brush I use. Give a smooth =
flow onto my bisque test tiles and prevents the water being quickly =
sucked into the bisque.

Have fun with your work.

Best regards,

Ivor Lewis,

Tommy Humphries on sat 12 oct 02


while most of the other suggestions are right on the money as to adding
glycerin to underglazes and such to make brushing easier, you can also make
your own "pottery watercolors" with underglazes and glycerin...mix a bit of
underglaze with just enough glycerin to SLIGHTLY moisten it...pack it
tightly into a small container, bottle tops make dandy ones...let sit
overnight to let it harden up a bit and you will have a good pat of pottery
watercolor, just dip your brush in water and dab it on the underglaze patty
and off you go!

Tommy

What percentage of glycerin do you add to your glazes?

Ilene

Pat Southwood on sat 12 oct 02


Dear Lily,
The scientist husband says try a chemist for larger quantities of glycerin.
Will try it with slip after a trip to tesco's this week.
Best.

Go to your local druggist. An independent pharmacist, not a chain store.
Ask the pharmacist to special order you glycerin. It should be very easy to
obtain and not that expensive. Normally comes in pints. One manufacturer is
Humco and I know they put it up in pints.

Likely, any major Chemical Supply House.

Ours here had closed up I think, oweing to too many Cash
deals for 'precursor' chemicals to unsavoury furtive
customers...

Anyway...

Need not be 'U.S.P.'

So...should not cost much...

Drug stores are probably the most expensive place to buy
glycerine. You
can buy it for $9.99 a quart at

http://www.vandykes.com/product/02000153/

It is used as a softening agent for cane (as in caned chair
seats). I
have seen it other places for $25-30 a gallon. A google
search will
help you find it quickly.

John

Tom,
50 cents for the empty bottle, 10 cents for the glycerine, 40 cents for the
distributor, the rest is overhead and profit for the store who kept it on
hand for the occasional customer that buys it.
Glycerine is used in quantity by bakeries and if you can find where they
buy it it is cheap. However it comes in barrels.
Try propylene glycol instead. It works about. the same as glycerine in
glazes and is regularly available from vet. suppliers for about 15 dollars
a gallon in gallon bottles.
And Lili, it is not poison. They feed it to cows for ketosis. It is fed to
us in food products - ice cream , etc.too, ( but not through the cows!)

Hi Lily,

Thanks for asking. Much better. He is out of the hospital and
everything is fixable. Probably 3 or 4 months of physical therapy,
healing ankle, knee and back, teeth implants, etc. He is a diabetic and
a very careful one. He tested twice in the hour before he started
driving and still went low and blacked out. Lots of soul searching going
on as to whether he can ever drive again under any circumstances. A very
dangerous disease, at least for some people.

Regards,

John
