Chocolat <– It's French…

I decided to do another bisque [<–French] firing before glazing and although I didn’t think I could fill the kiln, I managed to do it. It’s running now and should be done tomorrow. After I got it loaded, it was time to mix up a new glaze that I wanted to try after I had done some tests in the last glaze firing. This glaze will probably be referred to as chocolat [<–French] something or other since it's the color of chocolat [<–French]. It's important with my work to have the glaze be transparent or translucent to reveal all the shenanigans [<–Irish] going on on the surface of the pot so this one should look yummy but sometimes what looks good on a little test tile doesn't actually translate to well on a larger pot. Anyway, here's the chocolat [<–French]…


Well, just for discussion sake, I guess wollastonite is the worst glaze ingredient when it comes to humidity making it clump or solidify. This used to happen to me with plaster… of Paris [<–french], if I left the bag out for a couple months, then the plaster would be all chunky and became less and less usable. The wollastonite is usable but the chunks can be rather large, some as big as a baseball, and no part of the bag is left untouched by the solidification process. Initially, I tried to use a immersion blender after water was added to all the ingredients but there was still quite a bit that would not go through an 80 mesh screen. So I made a big batch and the added step is that after there’s a slurry, it gets transferred 3 cups or so at a time into a blender and blended. This works and it comes out smooth as a baby’s ear but I had a quite large batch and took quite some time to blend it all. I had help though and here’s a shot of my helper (a jeune fille [<–French]) screening the chocolat [<–French]…

    Ah oui, la jeune fille est tres belle!

    Lovely chocolat chaud colored glaze…

    We don’t have issues with wollastonite clumping here in the arid west – don’t miss humidity one bit.

    I like the chocolat color! yum:) Do you blunge your wollastonite first? I haven’t had issues with clumping but have a few recipes that call for the wollastonite to be dissolved in water first….maybe that would help?

      hi shawna, i don’t blunge first but maybe i should try it or dissolve in water… i’m still stuck on my mix dry ingredients a bit before adding water superstition from the old days, thanks for the suggestions

    Holy cats, I better get down to my moist basement and check that stuff—my glaze ingredients have been sitting out over a month!!!!

    Are we all just a little stubborn? Potters never make life easy!
    (Dutch) the cheap side in the family.
    Good luck with the glaze firing.

    Would you be willing to share this recipe or at least the base that you’re working with? I would be happy to recalculate it for you without the wollastonite. My wife has been totally begging me to make up a glaze just like what you’ve got there. Nice job!

    Lovely glaze! Sofia’s expression says it all (and boy can I relate!): Sieving glazes sucks! Hey, hope you are still planning to post your PVC glazing gadget? Pretty please? πŸ™‚

    • jim Says:

      hi miri, probably post it soon as i’m gonna use it soon but after the buildup you may be let down.

    Yikes. I haven’t mixed glaze in a while… perhaps I should check mine as well. I did make a feeble attempt to preserve the stuff by putting it all in big buckets with airtight lids that I bought at the Beer Crazy store. Those beer brewing whackos like to keep their hops and whatnot ‘dry’.

    Oh ya, and I LOVE the chocolat glaze.. I love chocolat everything, including the movie with Mr. Depp. πŸ™‚

    The chocolat [<–French] glaze looks ginchy [<–Beatnik]

    Ciao Jim, Bella la foto della tua assistente Sofia con la macchina per setacciare = Beautiful picture of your assistant Sofia with the funnel to sieve
