Craig,
Funny you mentioned Moose Creek. Roger Kaufman of the Iminerals Group (the
makers of Moose Creek) are currently running a 75 lb sample of fully
processed Feldspar and will have it ready for testing so if you want some,
let me know.
They plan a pilot scale test for next spring, something like 20 tons so that
will make enough available for manufacturers and end users to do full scale
tests of the product under actual conditions.
At the same time, the North Carolina Lab will give Iminerals the
recommendation for the correct processing scheme and a full plant is to be
built. This can happen if the product actually works for the end users.
As to Lili's non shivering issue, I bet the interface between the clay and
glaze is too strong to permit shivering. I concluded that as the flux level
increases, a point is reached where the body is so much like glass that it
will crack to relieve the compressive forces but no longer shiver except
perhaps at sharp corners.
Regards,
Regards,

The question to Clayart was actually a "non issue". Lily was
calculating some of her glazes and asked why some of the low expanders
weren't shivering on pots she'd had around for 20 years or so. It was a
hypothetical, sort of, glaze question.
But at least someone responded and I thank you for that. I'm still waiting
on the edge of my seat for some Moose Creek Spar.

Hello Michael:
Thanks for the update on Moose Creek spar. I still have some of the final
blend 200 mesh stuff that you gave me last year so I probably shouldn't be
greedy and ask for more. I sent some of the 200 mesh to Jim Robinson for
testing but I haven't received a report yet.
regards, Craig Martell Hopewell, Oregon
