These Glaze Tests were fired on Highwater Ellen Buff Clay. The Cones touched shelf at Cone 6. I did a 15
minute soak at top temp on MED. Started cutting manual
switches off at 5 minute intervals after the first 15 minutes.
This Glaze is Noxema Blue
Two Dips
Results
Bright Blue with smooth nice glaze. No
pinholes. I did two tests on this glaze. One
where I washed the test tube and the other
where I did not wash the tube. There were a
number of significant pinholes where I did not
wash the tube.

an almost lavender glaze, but had some

Nice glaze, tried this as I like the Jade Green
so much.
