One of our readers (Jeff Crowe) provided a different kiln firing curve. He suggested that we fire to 1400 deg F. We agreed to fire at 1375 deg F and report.
Well, the result wasn’t quite what we expected but it is translucent.
We took this picture as a way to document our results. It does look glassy. We removed most of the ceramic used for support. The pot looked quite good. I set this pot on the edge of my desk and then proceeded to knock it on the floor (only to watch it crash in slooowww motion).
Here is a picture of the pieces. Clearly much more translucent result.
