I try three or for times a day to connect to the net but something is
wrong. I must wait to the expert, in the meantime I will write about my
last ( for 2001) glaze tests.
Falls Creek Shino:
If you remove the Lithium carbonate: You get where thick, yellow kind
of gloss. where thin you get kind of matte Falls Creek Shino.
The following recipe was prepared in the studio away from the computer,
that was the reason for the lovely numbers:
I am very satisfied from the results.
It is not in the limits of the "foodsafe" By John Hesselberth and
Ron Roy, yet, much safer than the original.

Notes:
Needs more Rio
A very interesting glaze gloss should applied thick.
Make another test with one more RIO
