i actually did some tests with that same glaze a few months ago just to
experiment. At cone 11 it came out brown-ish in my kiln! Kind of
brownish/white or beige i guess you could say, and i did try it a little
thicker and a little thinner. Not a single trace of blue, pink or green
like you get.
What size is your kiln? I think mine cools especially slow for some reason.
