Ceramic cone temperatures.

The cones often used in sets of three are positioned in a kiln with the wares to be fired and provide a visual indication of when the wares have reached a required state of maturity a combination of time and temperature. Pyrometric cones measure heatwork the effect of time and temperature. Cones used on the kiln shelf bend due to the effects of gravity pulling the tip down. Pyrometric cones are pyrometric devices that are used to gauge heatwork during the firing of ceramic materials.

Cone temperature conversion chart. Pyrometric cones will be the first to let you know your ceramic firing is under control or that subtle changes. Pyrometric cones are used worldwide to monitor ceramic firings where consistent temperature is important to the quality of the final product being fired cones are used both in industry and by ceramic artists alike. Thus pyrometric cones give a temperature equivalent.

Generally speaking the temperatures in the 108 f hour column are used when discussing ceramics porcelain and china. Temperature equivalent chart for orton cones cone 022 14 pyrometric cones have been used to monitor ceramic firings for more than 100 years. As discussed above the equivalent cone temperature depends upon how fast one gets to it. Please note that the cone chart gives 3 different temperatures for each cone number.

During firing a cone softens and melts as it is heated. Ware and glaze types.
