Hi all;
Have to jump in here with a little experience with acrylic gloss medium. I
have used the acrylic medium used in acrylic painting the wet-on-wet
technique. Bob Ross or Bill Alexander, both had series on TV on instruction
on painting wet-on-wet techniques. They sell an acrylic medium to prime the
canvas before starting to paint as well as a clear for mixing colors. I
have used my clear as a resist on the pots before glazing as well as over
glaze as a resist for layered glaze patterns. I also use it on the bottom
of pieces that have a rough surface that may scratch furniture, Raku. Bob
Ross also sells a black acrylic priming medium which is great for the
bottom of black Raku pots. If you are looking for a really cheap acrylic
medium just to use for resist, I use Gesso. It is a primer used to treat
canvas to prepare it for a painting. Much, much, much cheaper, in fact it
can be bought in large pails. I use it all the time for lots of things. I
believe you can get it at hardware stores or paint stores.
For a resist over a glaze layer, I found the easiest thing to handle fine
brush strokes was Downey fabric softener. I didn't like it on the bottom
the pots in place of wax as it washes off during cleanup of the bottoms.
But on the glaze, just rub it off with a cue tip.

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.

Sylvia---
Right before I read your post, I purchased a bottle of Windsor Newton
(nothing but the best---as someone on the list said) acrylic gloss medium.
quite expensive. As I looked over the shelves at the store, I saw lots of
different types of gel mediums, gesso, etc. And I wondered---would
these work equally well--because they are much cheaper!! Okay--so
now I know for the next time....But here's the question----why GLOSS
only? There are matte mediums, too--and if Gesso works, wouldn't
matte work as well?
