Cones & temps
Bisque, glaze, and every cone in between.
Cone is a temperature, not a guess
A cone melts at a specific heat-work, not a specific degree. Kiln keeps the chart straight so your glaze and your clay actually meet.
The common cones
022–011 earthenware bisque 04–06 low-fire glaze 6 stoneware, electric 10 reduction, gas & wood 14 porcelain, industrial
Why it matters
Firing one cone off is the difference between a satin glaze and a puddle on the shelf.
