Orton Junior Cones

Orton Junior ConesPyrometric cones measure heat-work (the effect of time and temperature).

Pyrometric cones are 1 inch long slender pyramids made from about 100 carefully controlled compositions. The can be used in a kiln sitter. 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. 50 bars per box.
