Dear Imzadi,
think it is best to make small batches for immediate use. For better brush
ability, check the archives for a glycol mixture using CMC also. I don't have the
recipe here but I know it is in the archives from around '96.
Best wishes,
Marcia Selsor

I made up Mark's Copper Matte glaze/wash up a few months ago but didn't get
to use it until a couple of weeks ago. Copper Carb 90%, Frit 3110 10%, Red
Iron Ox 5%. When I did use it, it stirred up fine, nice and creamy. I had to
brush it on rather than airbrushing it, which I know is how this is usually
applied. It went on in an even creamy coat. But the glaze application turned
out too thin. (No great colors.)
I used the glaze again last night. I poured off the excess standing water,
stirred it up -- or at least tried to. The glaze was hard and concrete like
in the bucket. It would barely come off the brush. Just stopped still or
pulled where the brush landed and glopped up. I added back some water. No
difference in theconcrete quality. I was able to scrape off some of the
excess chunkyness off my pots. (Left some to see what effect it would give.)
At this firing, the colors came out those beautiful copper matte flashes I
have only dreamed of getting and envied seeing at craft shows!
Question is: What to do about this glaze settling in the future? Can I add
something to my existing batch, or is this now garbage? Is it best to make up
small new batches right before each firing? Also, should I add something for
brushability, since this is usually an airbrush recommended glaze?
Thanks in advance!

I use this, or similar, and yes - it sure does settle. I find a good stir
without taking off the standing water is needed before any application (I
normally use a small mouth spray, or dip) - it settles in minutes. this
seems to work even after a week or so, but I do prefer to mix up just
enough, rather than leave it up a corner.
