Low fire glaze on high fire clay?

Question

Low fire glaze on high fire clay?

Answer 1

BAD THINGS!! Everyone's really minimizing the damage here...



Stoneware gets fired to cone 10 and that will DEFINITELY melt the glaze. It's going to run off the pot, and ruin the expensive, expensive kiln shelves. Stop her before she does it!

Answer 2

The glaze might run or drip.

Answer 3

Probably damage the glaze, burn out the colors, unless the high fire has already been done and a low fire can be done on just the glaze. Teacher should know and will know from damage as soon as they are fired.

Answer 4

i dunno....

Answer 5

depends on your specific low fire glaze. It will come out different than you expect. It's more likely to not look that great, though some low fire glazes look different but still pretty good when fired at high temperature.



If your piece has already been bisque fired you can wash the low fire glaze off and put a proper high fire glaze on. Make sure you remove the old glaze into a slop bucket, not into the sink and down the drain. Most glazes contain metals which are toxic for the environment.
