The temperature at which cones squat, when heated at a standard rate, is known as the pyrometric cone equivalent (PCE).
Likewise, the same causes of cooling that operate in the everyday domain will bring objects from pyrometric temperatures down to everyday temperatures; that is precisely what happens in calorimetric pyrometry (or, when we simply leave very hot things out in cold air for a while).
All previously known thermometers failed in that pyrometric range, so Wedgwood felt obliged to invent a whole new measurement standard (reminiscent of Bridgman in his high-pressure laboratory).
The urge for conceptual extension, in the Wedgwood case, was rooted in a widespread feeling that there was a property in the pyrometric range that was continuous in its meaning with temperature in the everyday range.
The formulas of pyrometric Seger cones are listed in the appendix.
The two most common names or manufacturers of pyrometric cones are Orton and Seger.
Pyrometric Cones: A pyrometric cone is made of a ceramic material that bends and deforms at a predetermined temperature.
Pyrometers and pyrometric cones are accurate but tend to be expensive or difficult to obtain for a small rural producer of bricks.
The table on pyrometric cones listed here gives only some of the available cone numbers and corresponding temperatures.
A pyrometric cone is a cone made of a ceramic material that will deform or bend when a predetermined temperature is reached.
