I'm intrigued by this material, particularly the fact that it dries fast. Is
this just acrylic floor wax or some similar household product, or is this a
product for ceramic applications which is available through ceramic
suppliers?
Thanks!

From what I understand, this is a product found in any art store.
It's a medium used to make acrylic paints glossier, and also as a
protective varnish over a completed painting. LiquiTex, Rembrandt,
etc. Comes in 4-oz to 20-oz bottles, ranging from $6.50 to $22.00 in
my neck of the woods in San Jose, CA.
That's all, folks....

Acrylic Gloss Medium is the acrylic medium without the pigment. It is
fast drying, waterproof, and mostly non toxic.
You can buy Acrylic Gloss (OR Matte) Medium at
any "art supply" store with paints. DO
NOT BUY THE STUDENT GRADE of anything.
This will not work well.

ALSO...I just answered a question on the word "varnish" being included on
the label. If it says Acrylic Gloss (or Matte) Medium and Varnish, it's
the same thing. Calling it "varnish" does not change it as long as it's
main ingredient is the acrylic medium.

IMHO
Ceramul-A wax. the old type wax resist...? I think Calton Ball told us
that it was an emulsified wax...akin to floor wax. Can you still buy that
stuff from Laguna...now that it's not Westwood? That works....
and...
from my experience in experimenting with wax resists, acrylic medium works
and so do certain floor waxes...acrylic and otherwise. Can depend on what
effect/affect you're after. (Melted wax / parafin (sp?) in a heated pan
works too, but smells, smokes and can be a fire hazard ! ) Floor wax is
probably cheaper than acrylic medium for painting.

I wanted to thank everyone, and there were a lot of you, who responded to my
request for information on the Acrylic Gloss Medium. I got a trial size(4oz)
at Michaels but it is pretty pricy in that size ($6.23). I'll wait till I get
one of their forty or fifty per cent off certificates and buy the larger
size.
Thank you all!
Warm regards,
June

A recent post stated that acrylic gloss medium is mostly nontoxic. Maybe
this newsgroup has made me paranoid, but I've got some environmental
concern about burning acrylics. Maybe someone with more chemistry
background could comment, but it seems like waxes burn into nice stuff
like H20 and CO2, and plastics burn into noxious gases. It seems a
shame to burst the bubble, since a great resist would be a great
improvement. Any other points of view on this are welcome.

Essentially *nothing* is non-toxic once you start heating it to the point of
decomposition or to the point where it burns.
Waxes heated even to candlemaking temperatures produce acrolein, paraffin
fume, formaldehyde, and a host of highly toxic chemicals. Ironing out
batik, lost wax casting, or burning waxes off in the kiln produces
highly toxic gases and vapors in large amounts.
When you look at a wax MSDS under "decomposition products" and see only H2O
and CO2, they mean burning in incinerators with very high temperatures and
*complete* oxidation. This is not what happens when wax heats or burns
in the open or in your kiln.
Plastics that are made of only carbon, hydrogen and oxygen like some of the
polyols and styrene resins will also incinerate to water and carbon dioxide.
But incomplete burning produces a host of highly toxic chemicals.
Plastics that contain nitrogen such as urea formaldehyde resins, urethanes or
nylon will give off water, carbon dioxide and HCN (hydrogen cyanide) on
incineration. Incomplete burning produces the horrendous gases that are
associated with so many smoke inhalation deaths on planes and in buildings.
Most acrylic mediums are non-toxic for the *directed purposes only.* Some
(those co-polymerized with nitrogen-containing acrylonitrile) will give off
cyanide on burning and some will not.

Acrylic gloss medium is mainly alcohol (PVA) and the acrylic film it
deposits is similar to household paints. Strangely enough, these are
tested for the release of noxious fumes in fire situations.
Even so, I would certainly not wish to be breathing anything that exudes
from an operating kiln.

In response to a couple of points raised recently -
I used Gloss medium as opposed to matte because it has the higher
adhesive quality. Also, I thought that matte would not be readily
visible on bisquit. That was before I thought about adding colour.
Someone suggested acrylic gesso as being cheaper. It is not cheaper here
- mainly because it only comes in large pails, which I find difficult to
use as a paint pot and messy to pour/dip for smaller quantities.
I also believe that gesso is what we buy as Acrylic Medium but with
chalk or gypsum added to provide an absorbent painting surface. It did
occur to me that calcium is a flux and that at the higher temperatures
at which I fire it might give me much grief. I once used a surplus Xmas
gift of talcum powder as a shelf wash and it turned out to be more CaCo3
than MgSiO2 with disastrous results!(I don't think it was Avon....)

Hi Judith
I am interested in your technique of using acrylic gloss medium. I have
heard it mentioned before (as a resist) but I have yet to try it. (Another
thing for my list of "things to try") What cone do you fire to and is the
application to bisque or leather hard clay?
Could you explain what you mean by combining the medium with underglaze
colorants? Are these liquid or powder? If they are a liquid why would you
need the AGM? I thought they didn't "move" anyways. But maybe I am
thinking of the wrong thing?
Any information/insight would be helpful to get me on my way in terms of my
own experimentation. Thanks.
