Orton Pyrometric cones measure heat-work (the effect of time and temperature). They are slender pyramids made from about 100 carefully controlled compositions. Each cone number is unique in measuring temperature within a small temperature range (less than 30°C). Cones measure the amount of heat absorbed. As the cone nears its maturing range, it softens and the tip begins to bend, drawn down by the influence of gravity. Self-Supporting cones are used as a visual aid to monitor the firing and verify temperature uniformity.

For more details on cone temperatures consult our cone charts to the left under More Information.
