Hi Jeni;
I found out about using acrylic medium on pottery as a resist, when I
enquired about refiring a piece, and how to get the glaze to stick to the
pot. It was suggested to me at that time to either paint the pot with a
white glue or acrylic paint, or to mix glue or acrylic into the glaze to
make it stick to the glazed piece. I have tried it and it burned out
completely at cone 6. I thin it to a consistency easy to handle for brush
stroke designs. I did find I needed to add a bit of veegum to my initial
glaze to give it a harder glaze surface, rather than powdery, to paint on
as resist over a glaze. As for the toxicity of the fumes, I have no idea
and really didn't think about it at the time. I fire in an electric vented
kiln, in an area away from my studio, so never noticed the smell like you
do with the wax. I found the wax resist very sticky to handle painting
resist patterns on pots or glazed surface and I'll be darned if I can paint
with regular parafin wax without managing a few drips here and there that I
get really ticked off with. I have also never mastered the dipping the
bottoms into parafin in an electric frypan without getting though annoying
air bloopers that give that terrible half-moon on the bottom of the pot so
I take the time to paint my bottoms with wax resist or future floor wax
(prefer the future wax). Gesso is an acrylic medium you mix with water to
thin, and gives a flatter finish than the expensive acrylic paint. You will
find the consistency you like to work with, and if you just thin down a
little to start with you can always thicken it by adding more gesso.

The golden years have come at last, I cannot see, I cannot pee,
I cannot chew, I cannot screw. My memory shrinks, my hearing stinks.
No sense of smell, I look like hell. My body drooping, got trouble pooping.
The golden years have come at last, The golden years can kiss my Ass.

It also contains considerable whiting, which may affect your glaze.
