Mid-Fire (Cone 5-6) Ceramics
Mid-Fire or Mid-range Ceramics are terms commonly associated with a Cone 5-6 firing. There are discrepancies that exist over the use of the term as many potters consider anything over cone 5 "high-fire". Veteran potters will only consider cones 8, 9, 10, 11 high fire but many people are realizing that those higher temps are unnecessary and use excess energy. People use Mid-range firings to achieve the durability and appearance of high-fire work in a more energy efficient way. Mid-range porcelains are becoming very popular these days.
It is easy to accomplish in most kilns and can produce vitreous ware with spectacular glaze effects similar to what can be achieved in a gas kiln, especially if control is maintained on the down ramps.
Typically the cycle for mid-range involves a bisque firing from anywhere between cone 012 and cone 04 and a glaze firing to temperatures from cone 5-7. People fire to mid-range temperatures in both electric, gas and alternate fuel environments.
