I recently started using a glaze I found on the glazebase (thank you,
Brian Kemp). It's worked out really well for me - so much so, that
it's becoming my signature glaze.
My trouble is this: after dipping, the glaze dries to a somewhat
powdery consistency on the pot. Is it possible to add something to
it, say, CMC or the like, so it can be handled a little easier? Will
adding a gum or something change the behaviour of the glaze? (I get a
nice, smooth finish right now. I'd hate for it to turn streaky on
Thanks in advance, Clayarters.

Yes, CMC gum works very good in glazes. This product was used excludively in a
glaze book I purchased, and now I use it in every glaze I mix up. It keeps the
ingredients bonded together on the pot and doesn't chip or flake off as
easily. Try it, you'll like it!

Could you help me a little more please? Perhaps I missed this info, but
how do I use the gum? Have a bag of it and don't know how to mix, how
much etc. (Sorry if you already told and I missed it.)
Also, do you think this might help a problem I'm having with one glaze.
When I dip, it drys with bubbles showing, some of them big donut bubbles,
and they show up on the pot after firing. Ugly!

Here are the directions for mixing CMC gum:
Add 25 grams CMC to one quart of water. It will take a day or two for the gum
to dissolve, so make ahead of time. Then when you are mixing up your glaze,
add one teaspoon of the mixture per 100 grams of glaze. So if you are mixing a
500 gram batch of glaze, add 5 teaspoon of the CMC mixture. The book says to
add 2 - 3 drops of formaldahyde per quart, but I don't have any and haven't
If I get small bubbles, after the glaze dries, I just run my finger over and
smooth out the surface before firing. You will find that the glaze sticks to
the pots well and is not powdery. It doesn't flake off as easily.
