Hello, I am a new member (and new to pottery in general) and have struggled to find the answer to the glaze defects I have been experiencing on previous posts in this forum. I am having trouble with pinholing/pitting/airbubbles (not sure exactly what to refer to it as). Most of my glazed pottery either has loads of little holes (this is especially bad with black underglaze topped with clear) or lots of tiny bubbles trapped beneath the surface. To provide a background, the clay I have been using is Scarva Earthstone ES5 Original White Stoneware Clay, which has a firing temperature of 1200
Hi there. I recently glazed some items on white stoneware clay. The clay (White Stoneware PF560) was glazed fired after being bisqued at : room --> 600 degrees C at 100 deg/c per hour 600 -> 1230 at 150 deg/c per hour 20 min soak It came out really patchy and there are some air bubbles. If anyone could recommend good firing ramp for this glaze in degrees celcis with timing that would be great - thanks so much Terracolor orange Ember - https://www.scarva.com/en/gb/Terracolor-FS6031-Orange-Ember/m-1772.aspx was the glaze that didnt look very good!
