Despite the lithium carb, I had to test this because I like tenmokus so =
much.
I found this glaze to stay on the clay with no flaking. However, it had =
to be applied
relatively thick to get any shine on the surface. Otherwise it showed a =
rather dull brown
semi mat where thinnest. Tempting to continue to test this glaze, =
because it shows a
very nice sparkle on the surface and a bit of black in the surface where =
thickest. But the lithium
makes me want to shelf it. Sigh, because the sparkle is almost =
bewitching.

Alisa,
Thanks for posting this information on your glaze testing. It's always
helpful to know someone else's recommendations and experiences with a new
formula.
I'm curious. Why would you shelve Gibby's Wild Rose because of the lithium
content? Is it because of lithium's high cost, or it's toxicity? I wouldn't
use this glaze on the inside (and probably not the outside, unless I was
absolutely 100% sure of the continued fit) of food containers even if there
was no lithium, but it's a beautiful glaze, as you said, and if it fits your
clay, why not use it where it's appropriate? Someone correct me if I'm
mistaken, but I see no reason not to use lithium because of its toxicity in
a working environment. We wear a proper mask even to mix silica, and this
should certainly be adequate protection for working with lithium.
