My partner and I have been using the Pinnell strontium carbonate
glazes for the past year and usually have successful firings. We
have been ordering our strontium carbonate from Minnesota Clay, and
it seems that the strontium carbonate they supply is a granular type.
Recently, we obtained some strontium carbonate in a powdered form
from a local supplier. The glazes we mixed from that supply gave
unsatisfactory results. The black strontium glaze was an olive green,
the texture was rough, etc. The periwinkle blue was a whitish color,
the glaze had a powdery finish, etc.
We deduced that this glaze recipe is dependent on the granular
strontium carbonate for best results. Has anyone else had this
experience?

Hi Bridget,
I've tested and used all the Pinnell strontium glazes. Originally I used the
granular strontium and couldn't get it to mix up. The results were awful!!!
The glazes came out dry and sandy and the colors were really crappy! Then I
bought some chemical grade strontium and the results were smooth and buttery
and the colors are great!

Charlie,
I bought the chemical grade strontium at Free Form in National City, CA and
Armadillo Clay in Austin, TX. I imagine any clay supply could supply you
with the chemical grade if you specifically ask for it. Armadillo's phone
number is (512)385-7311. Hope this helps!!
