Anyone have a good idea for how to remove water from a glaze that
absolutely refuses to settle, but whose specific gravity indicates
too much water?? I don't have access to plaster bats, and don't have
any large bisque bowls on hand. Other ideas??

I neglected to mention that, yes, I was looking for something a
little quicker than evaporation. Maybe because it doesn't settle
(or maybe because it's 50 degrees in my studio?), the water also does
not evaporate quickly from this glaze -- I left it uncovered for
three days and found virtually no difference in the specific gravity.

Hi Chris,
can't say that I have ever had a glaze that didn't settle enough to take out
water. Why not just mix up more dry glaze with a little water and add it to
what you have.

I read somewhere that it is possible to make a cone of newspaper and push it
into the glaze with a colander or sieve. The paper acts as filter. Water
will fill up the colander.

Chris,
Use newspaper. I usually pour my glazes in a large bowl and lay several sheets
of newsprint over the glaze and watch the newsprint soak up the water. If
there's a lot of glaze stuck to the newsprint, I use a rubber rib to scrape of
the glaze from the newsprint back into the bowl. I'll loose just a small
amount of glaze, but it's worth it. hope this helps. Richard Ramirez,"The

If you've a camping stove, stick the glaze in a pail, bung it on the stove and
boil the water off. You can do this in the kitchen as long as your significant
other doesn't mind, but I should check first, just to be certain :). Or, you
could add a flocculant ( epsom salts,plaster of paris, calcium chloride ) to
the glaze and decant the surface water. I'm assuming there isn't a filter-
press in your workshop.

Chris,
It almost sounds like this glaze is in solution instead of suspension.
It would help if you posted the glaze recipe.

Chris,
You could try flocculating the glaze a bit with some vinegar (maybe a
teaspoon) and then warming the glaze (Hamer says this encourages a type of
flocculation.) Assuming these two work, after the water's off, you'll have
to go about deflocculating the glaze again. If you've been using Epsom
salts, you might try switching to Darvan7. Slowly add 1/4 teaspoons until
it thins up enough to properly coat a finger dipped into the glaze.
With Epsom salts you can over-deflocculate to the point of going back into
flocculation...the opposite of what you want.

I would just leave the opened bucket of glaze in a warm room (maybe the
kiln room) and let the excess water evaporate---rather a slow method, but
it should work. I'm envious of a glaze that "refuses to settle"---most of
mine settle way too well!

I started out with nothing, and I still have most of it left.

Set a fan to blow across the surface of the bucket,
pour it into a large shallow pan
remove some & cook it till it thickens then add to the rest of course do not
use a container that is used for food.

Doesn't work in all instances...but try this.
Put one end of a strip of cloth, preferably an old towel, about 1 to 2
inches wide, into the glaze. Have the glaze bucket raised on something with
a container to catch the water next to it. Put the other end of the cloth
into the lower container. (The end outside has to be lower than the end
inside)
You're using the capillary action of the cloth to siphon excess water from
the glaze. If it's sluggish, wet the cloth to get the flow going. It'll be
slow, but it should work.
If there are any soluble ingredients in the glaze, they will wick out too,
so be aware of changes in chemistry.
