Electric Kiln Cone Chart

Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years.

Electric kiln cone chart. Ceramic work is typically fired twice. Three ways to fire an electric kiln oxidation. Ware and glaze types. The kiln requires ample air during this stage since after 800 c sintering begins and the clay surface begins to seal off.

During firing a cone softens and melts as it is heated. These are used to hold and protect the edges of pieces in low to medium low firings. Kiln cone temperature calculator. Turning the kiln on and off using orton small pyrometric witness cones in the kiln sitter.

Cone temperature conversion chart. Though some stilts may be able to stay in form at cone 10 most are better suited for temperatures at and below cone 6. They are available to order in many. Stoneware glaze some decals fire to cone 10.

Cone 022 is the lowest melting cone and requires the least amount of heat to deform or bend. 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. Firing clay from mud to ceramic. They are useful in determining when a firing is complete if the kiln provided enough heat if there was a temperature difference in the kiln or if a problem occured during the firing.

The goal of bisque firing is to convert greenware to a durable semi vitrified porous stage where it can be safely handled during the glazing and decorating process. It is bisque fired and then glaze fired. Calculate kiln cone temperature for cone 022 to cone 10 based on the kiln s heating rate. Cone numbers orton makes cones from cone 022 up to cone 42.

Since earthenware is softer than other clay bodies it seldom becomes fully vitrified meaning it will be porous absorb liquids and be less durable. Kiln posts support shelves while optimizing space within the kiln for firing.
