Cones - Small

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

  • 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.
