Hi Dan and all,
I can hardly believe this because I did it just yesterday. I had a
blue slip I had quit using because it smudged too easily and
yesterday I decided to try again and went to my Bailey's catalog and
looked up CMC and Veegum C to review the differences as I have both
made up.
Veegum C is a combination of CMC gum and Veegum T which is a
macaloid clay like bentonite. It tells you to wait 24 hours after
mixing this to let it thicken. You make it in the blender by pouring
the powder very slowly into the liquid while going at lowest speed.
Store it in tightly closed jar and you're in business. Anybody know
if this mixture has a shelf life?
I mixed my cobalt slip with equal part made up Veegum C, mixed it
real good, and, lo-and-behold, you couldn't smear that brush stroke
no matter what. Just can't figure out why I didn't try this before
now. (Or, more likely, I did try it but didn't use any where near
that much gum.)
This brushwork design is what I earned my bread on in the 70s at
high fire, over white glaze. I was never able to translate it
successfully to lowfire and moved on. But I always kept using those
dishes and wanted to get back into it for myself. Well, happy me
started where I left off with the old design and quickly moved into a
completely new rendition of this old old tune. I will see how it
comes out in afew days. So nice to have a little pearl on the back
burner come to new life.

know if this mixture has a shelf life?

Dear Eleanora,
Bacteria regard any CMC product as lunch. Once they colonize your solution
the enzymes they secrete attack the CMC and reduce the thickness. At that
point killing the bugs won't help.
Solutions will keep for as long as you keep them bacteria free.
Barring antibacterial additives I would just boil the water you use and
sterilize mixing equipment and containers beforehand.
Either that or use Ball jars to keep it in and boil them before storage,
just like preserving fruit etc.
Regards,
Derek in Weaverville, NC

Dear Eleanora;
The Vee Gum with CMC in it will have a shorter life than the straight
Vee Gum Cer without CMC. I use it extensivley in my glazes.
Cheers, Hank
