G enerally speaking cone 10 electric kilns are perfect for regular cone 6 firing and occasional cone 10 firing.

Calculate kiln cone temperature for cone 022 to cone 10 based on the kiln s heating rate. If less time is being taken to fire more temperature will be required to achieve a particular amount of heatwork. Ware and glaze types. Kiln cone temperature calculator.

Less than 5 of people with electric kilns actually fire them to cone 10 but in case you are looking to fire to cone 10 all the time please read our tip 106 on true cone 10 kilns to help you pick the right kiln.

Likewise if more time is taken less temperature is required. You will experiment with this for your individual kiln. Jennifer poellot harnetty editor. Mostly yellow with a hint of orange.

Take cone 08 for example. For mid range material a kiln should be firing at a temperature between 2124 and 2264 1162 1240. If the kiln is ramping at 108 f per hour the temperature that the cone melts will be 1728f. When kiln temperature reaches cone s specified temperature it will melt and will trigger the kiln to turn off see appendix a for more information about cones.

Electric kiln firing is one of the most common methods for firing clay because electric pottery kilns are readily available and simple to install. Stoneware glaze some decals fire to cone 10. The firing log will assist you. This ensures that.
