I recently changed to a different wax resist emulsion - Forbes Wax - and
had a problem that I had never encountered before. I am wondering if any
of you have had this experience.
I had 3 bisque pots to which I had applied some decoration using a stain.
I applied a coat of clear glaze over the decorated area only. Several
hours later, after the glaze had dried, I applied a coat of Forbes wax
over this glazed area. My intention was to pour a colored glaze over each
entire pot, with the waxed area resisting this colored coat. I left the
wax to dry overnight, and when I came back the next morning, the wax had
curled up and peeled away from the pots in irregular strips, taking uneven
thicknesses of the underlying clear glaze with it.
I have used this resist technique this before, using a different brand of
wax resist, without problem. I do know that the previous wax resist
always felt slightly sticky on the surface, whereas the Forbes left a very
smooth, non-sticky surface. (This is actually why I changed brands.)
Anyway, I am wondering if any of you have had wax peel off like this, and
whether you have any clues as to why it happened.
Thanks,

I've also had this problem with Campbell's wax emulsion.
Getting ready to put in an order for more wax emulsion.
Anybody have a brand that works well for over glaze application?

Have had no trouble when using the following:
plain old wax resist from Axner or MN clay
melted paraffin in an old electric fry pan used with a sponge brush,
piece of sponge or reg.
brush
Picked up some latex that I really like but, it has to be peeled of before
firing.(also requires a supply of inexpensive, throw away brushes because
the brushes are unusable after the latex).

Bill -
Forbes wax resist works great and you can thin it down quite a bit. For
decoration over glaze, I like to thin it down to the consistency of skim
milk. You can order it from Highwater Clays in Asheville, N.C.

Victoria - the Forbes wax is exactly what I used that caused the peeling
problem over glaze. If you have used it successfully over glaze, I would
like to know how you applied it, etc.

Try latex resist. I have used it successfully over dried glaze. You must
peel it off (with a pin) before firing but it comes off without lifting the
underlying glaze.

Hi Carole -
Hmmmmmm,interesting.
Well, I thinned it down pretty much to a sort of skim milk consistency and
then applied it with a natural hair (sheep, horse, something like that)
brush. As it dries pretty fast, I then apply my second glaze over the
resist. Usually these pieces will sit for a day or two before I load them
in the kiln.

Victoria - the Forbes wax seems pretty thin to me in its original state,
in fact it tends to run quite easily. Could you give me more specific
info about how you dilute yours? It would be easier to follow a formula,
e.g., 1 part wax emulsion to 1 part water, than to try to approximate the
consistency of skim milk. As for application, I used natural hair brushes
as you do. The resulting layer of wax when dry was pretty thin, a bit
thicker on one pot than the others, but with similar peeling.
I am also wondering if there are any characteristics of the underlying
glaze that would have contributed to the peeling of the wax.
I had sent an email inquiry to Highwater Clay last week, but have not
received a response yet. Anyone else have any thoughts?
Thanks,
Carole Fox,
