Hi Cindy:
John's reply is certainly correct, but not always practical. I do alot of
glaze-on-glaze accents, in sometimes intricate patterns, where there just
isn't time to apply subsequent glazes while base or field glaze is still
fresh and not bone dry. Plus, I often work on several pieces at a time,
one glaze color at a time, over a period of hours.
I spray (with a spray bottle) CMC gum solution to "seal" the field glaze
and take brush work better, but found that some of the accent glazes would
still "jump off the pot" during firing. So, I still use the gum solution
to seal, but also to dampen the underlying dry glaze as I go - to "marry"
the glaze layers as I apply them. If I get going and forget, I carefully
spray and dampen the decorated area of the pot when all is done. I no
longer get patches of "leaping" glazes on my shelves.
You can buy the gum solution or mix yourself. Happy potting!
