Bisque Fire Results 🔥

Pottery Wheel Thrown Ceramics made by Little Clay Studio in Austin, Texas Bisque Fired in the Kiln. Large bowls and oversized ceramic plates for serving at parties and at home.

The clay transformed from greenware to bisqueware, and the kiln fired perfectly. Skutt electric kilns are computer programmed, easy to fire, and reliable in results. They’re the microwaves of pottery firing.

A cone 06 bisque fire reaches 1828F (997C). This temperature is hot enough for cones 5-10 clay to transform from greenware to bisqueware. Bisqueware is partially matured clay that is porous enough for glaze to adhere.

Electric kilns heat ceramics in a controlled oxidation environment and can be programed from 100F (37C) to 2380F (1300C). This temperature range allows you to dry greenware with a preheat setting, fire overglazes at cones 020-018, bisque greenware at cones 04-06, and vitrify glazeware between cones 5-10. The oxygen interacts with the chemistry of the developing glazes and clays, enhancing the vibrancy of your work.

Gas kilns are known as reductions kilns and eliminate oxygen by adjusting the amount of fuel that powers the fire. The results are muted and earthen. White glazes take on bluish-grays and the clays darken. Both oxidation and reduction effects are desirable and it’s worth considering how you want to fire your ceramics.

Pictured is the top shelf of this week’s bisque load, so in total I have eighteen pieces that will be wet-sanded and glazed with a white cone 5 glaze.
