I tested Chappell's Floating Blue glaze base and added chrome and tin to try
a burgundy glaze, but got a nice very light opaque shiny mint green glaze.
Thought I was going to get a burgundy, but it turned green. It is a nice
glaze just not the color I wanted. Will go back to June Perry's Chrome Red.
Here is the recipe.

Randy,
I tried the same thing a few months ago, except I used
5.0% tin with 0.15% chrome oxide (same proportions as in
Kemp 17 pink-purple) instead of the 2% chrome you used.
My results, like yours, were greenish but rather light,
no doubt due to the tiny amount of chrome.
Actually, the Floating Blue base without cobalt is a
pretty nice glaze in its own right. On porcelain I got a
light tan where thin, but a pale pink where thicker.
Haven't used it much, but was plesed with the results where I did.
Cheers,
