Hi, Marianne!
I am glad that you are thinking clay, and feeling better!!!
All of my glaze application is done by brushing. I always add, either
glycerin, or propylene glycol (the non-toxic component of antifreeze) to the
glaze. I believe that this improves the flow from the brush, and slightly
retards the drying, so that glaze has a chance to smooth itself out a bit.
It makes brushing a pleasure. I wrote about this previously, but it bears
repeating. When I prepare a glaze, I usually make up about 300 g (dry
weight), since I like to use many colors/glazes. To this, I add 0.5 - 1.5%
Vee Gum Cer (contains Vee Gum and CMC). The dry materials are slaked into 1
cup of hot water, and sieved twice - 60 mesh and 80 mesh. Finally, I add 1
tablespoon of glycerin or propylene glycol (ordered and bought at my local
pharmacy). The glazes are well suspended, and flow beautifully. Now you can
apply your glaze easily, even to bisque, if you have first wet the piece to
control absorption. I apply from 1-4 coats of glaze, depending upon the
effect that I want, and whether the glaze should be applied thickly, or
thinly.
Hope this helps you, too Charles.
My best,
Paulette Carr

Marianne,
As someone pointed out recently, polypropylene glycol is the same thing
essentially, but safe, not toxic to animals. Think of using that instead
so that you don't have the possibility of antifreeze bing ingested
accidentally.Available at feed stores.

Yes, it is ethylene glycol. It has a sweet taste that is attractive to
cats and dogs, and will destroy their kidneys. Renal failure is bad news
for man or beast.

Regarding the posted recipe for an Underglaze formula using Mason stains, I
am wondering about the antifreeze in it. My guess is that is what is giving
the smoothness for application by brush. Now my question is, would adding
antifreeze to glaze formulas do the same thing?
I have commercial glazes which apply smooth as silk. Some of these jars are
three years old, and they are still good after a bit of stirring. Could
antifreeze be the magical ingredient? It's not CMC because I've used that
and it's not the same at all.
When I get back into clay again and making glazes, I'll try adding some
antifreeze to a test batch, and see for myself. But meanwhile, I'm
wondering if anyone here is "in the know"?

Regarding the Underglaze formula--Is there a particular kind of antifreeze
to be used in the stains?

Were we not told during the Glycerin Period that glycerine is/is like
glycerol and that i think is the magic ingredient in antifreezes. No?

Awhile ago there was discussion of antifreeze as an addition to underglazes
etc and I believe that polypropylene glycol is the non toxic product (vs
propylene glycol which is toxic - let's hope I remembered this correctly).
(There will be something in archives if you search these two words.)
At any rate I duly went off in search of poly-p-g and got some - yellow
stuff this was. I like it in the maison stain engobes and recently added a
dash to some glaze that I was painting on and it helped with the flow. In
the past I have used glycerin in the engobes and think the antifreeze seems
unsticky by comparison.
Glad to hear you are progressing well, and planning new things, Marianne.

We had a big discussion on this detail awhile back after I first reposted
that underglaze recipe that Harold posted here years ago. It was decided
that Sierra Antifreeze was the right one as it didn't have a particular
toxin in it, can't remember what. So I have my gallon of Sierra antifreeze
that I utilized one ounce out of.

I submitted this late last night, but, as of this hour, it doesn't look like
it made it. In the interest of passing the information along, I am
resubmitting it. If it shows up as a repeat, please accept my apology:

Antifreeze is called for in under- and over-glaze recipes to make
them flow easier and brush smoothly.
What is actually needed is propylene glycol, and antifreeze is
an easily available and cheap source.
It is most important that you use "non-toxic" antifreeze.
It will be few bucks more than the cheap stuff, but it is
propylene glycol and it will say so on the bottle.
Regular anti-freeze is, I believe, ethylene glycol.
Propylene glycol is used in all kinds of food products. It looks
like a light colored motor oil. When I worked at the ice cream factory,
I added a whole gallon to the ice cream mix. Not really that much,
since we made 500 gallon batches. It was still disgusting to
think about.
