So, I got some CMC yesterday to make some of my new glazes stick better.
Had to buy a freaking pound of it, but oh well, now I am set for life. I was
discussing it with my husband (the chemist- lol) and he said, "Oh, you could
have just used KY-jelly. It's the same stuff."
This got me interested, so I looked it up, and while it's not exactly the
same stuff it's pretty close. CMC is carboxymethylcellulose while the main
ingredient in KY is hydroxyethylcellulose. So I looked up HEC, and it's used
for much of the same things (thickening, suspension, etc...) . It got me to
wondering if you could use KY jelly. I don't know why you would, maybe if you
were in a pinch or something.
There's really no point in this post, but I thought it was interesting.

Leigh there is a point to your email. Its to show the diversity in the
products we use. People like John Britt and others have made cone 10
glazes using everyday products that you get at the grocery store.
Although not very cost effective.
Tums
Alka-seltzer
calamine lotion (bentonite)
Toothpaste
Heck, people even eat sodium bentonite mixed in water to aid in digestion.
I think Tio2 is in twinky cream and cmc gum is used as some binding
agents in foods.
So thanks for the post, I find the diversity of products we use very
interesting.

Leigh,
I have used "personal lubricants" with some commercial
glazes
to make them flow better and stay wetter.
(Geez I may have a future career as a poster child for
personal lubricants
after that statement.)
They actually work very well for this purpose if one is just
using a small amount of glaze.
I forget who told me about this trick, but they probably
wouldn't want credit anyway.
Kathy

Another thickener is called "Thick-it". It's a derivative of cornstarch but
doesn't have to be heated to thicken. It's made to thicken liquids for
people, particularly stroke patients, who have trouble swallowing liquids.
Imagine water with the consistency of pudding! I bought it to help keep
oxide washes from running. A medical supply store may carry it, I got mine
from the manufacturer. I only mix as much as I use at a time as the
thickening power decreases after a time.

Which leads me to ask those what have they used and what happened?
Did it work well and in what proportions? Warmly, Kathryn in NC where
it was a seventy degrees today and not a snow to be seen in the
horizon. Great day to play hooy from work.
