I tested your Gibby's Wild Rose Tenmoku the other day and threw in 10gm
silica to your recipe. It appears to be a lovely brown semi- matt glaze that
breaks redish. Now I have not done any of the attendant tests, so I don't
plan on making any large batch of it just yet. I have a mug and bowl being
worked over by the family and will do the freezer to boiling water test
soon. I'm pretty sure it won't shiver, I have a bit of an eye for the
shivering type glazes.
The glaze was tested on Tucker's mid-porc 5 and it will also work on Tuck's
Mcs. Don't be fooled, you can have a wonderful glaze, works perfectly for
years and then some material they use in the make up of your particular clay
body changes and affects the bodies C.O.E. This can happen even with the
best of clay makers. The glazes that we use might be just on the cusp of
this glaze defect, and that can be just enough to send it over the
proverbial edge. The last part was a bit of a rant from a very, very bad
experience. The point is this glaze looks and feels great. Ronald, I know
you're out there somewhere twiddling with some sort of "delapitator" but
what I would like to know is: Do you still suggest only 2% lithium when a
frit is employed? Will not the frit solve the migration problems with
lithium carb. Is F-493 soluble?
Thanks Cindy
