Orton Mini-Bars
Pyrometric bars measure heat-work (the effect of time and temperature).

Pyrometric bars are designed for use in a kiln sitter as are made from about 100 carefully controlled compositions. Each 1 inch bar has a number that is unique in measuring temperature within a small temperature range (less than 30°C). Bars measure the amount of heat absorbed. As the bar nears its maturing range, it softens and begins to bend, drawn down by the influence of gravity. 50 bars per box.
