Orton Pyrometric Cones - Self Supporting Large Cones
Box of 25 Large Self Supporting Cones
Cone 019 Out Of Stock
Choose from the available cone numbers under PRODUCT OPTIONS above.
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.
