Pyrometric cones measure heat-work (the effect of time and temperature).

Orton Pyrometric cones 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.

Large Cones require placement in a Cone Plaque or clay pad and must stand at an 8-degree angle in order to bend properly. Large Cones come in a box of 50.
