Hi:
Quite some time ago, Karen Gringhuis sent some info to Clayart about
blunging Vee Gum the night before you mixed porcelain to fully hydrate the
stuff and to get better workability. I resisted that idea saying that I
thought that blunging wouldn't make that much difference. I was totally
wrong. I tried Karen's method and the difference in the clay is remarkable
AND, there are no problems with those irritating little micro bubbles from
pockets of non dispersed Vee Gum.
Thank you Karen and my apoligies for being a dope.
regards, Craig Martell in Oregon

when making porcelains that use macaloid or veegum, we always blunge them
first. 12 pounds will jell up a lot of water, it makes quite a mess. It is
the only way to avoid little jelly bits in the clay.

After talking to Conrad Rieger at Vanderbuilt, I discovered that we probably
all use too much Vee Gum T in our glazes and clays. The particle size is so
small that it takes a long time to get it wetted down completely. Blunging
the night before you use it may not be long enough.
I routinely prepare my glazes a week or more before I am going to use them
if they use Vee Gum T.
It really does help the suspension. However, if you use too much, it will
thicken up over time and will be difficult to use.
1/8 of 1% is usually enough to do a good job.
