I mixed up a small test batch of Jessica's Chun Blue. Came out a really pretty, transparent blue on my first round of tests. However I'm having a *lot* of problems keeping the ingredients suspended. Seconds after I mix, all the solids drop out and if I let it sit for more than a minute I get panning at the bottom. The quickness of the solids dropping out makes it nearly impossible to get a good coating of glaze, either brushed or dipped. I'm sure spraying would be the same. The copper carbonate lodges on the bottom and is very resistant to stirring.

I tried adding about 2% Bentonite and am about to run some more test tiles but I don't have much hope - all the copper carb is still dropping out immediately after mixing.

My conclusion is that there is no way to use this recipe as-is.

My question is what else can I put in the glaze to make it a bit more friendly and if anyone knows what Jessica adds.

I am having the same problem with the chun blue. I took it to my local studio and they added bentonite and tested the specific gravity at 1.5. I used it on one bowl, brushed on 3 coats and it was a very thin coverage. It is impossible to mix as it is a hard lump at the bottom of the jar.

I use this trick with the glazes that hard pan. I line the bucket 1st with a large thick garbage bag.Then I just move the bag around to brake up the glaze & start the mixing. Maybe this might help.

Did you ladies make this glaze from the recipe, or did you by the pre-mix from Clayscapes? I am in Australia, and made the recipe from chemicals. I have had no trouble.

I purchased mine as a dry mix. Will wait for spring to repurchase as a premix as it could freeze in transit now.
