The pyrometric cone is "A pyramid with a triangular base and of a defined shape and size; the "cone" is shaped from a carefully proportioned and uniformly mixed batch of ceramic materials so that when it is heated under stated conditions, it will bend due to softening, the tip of the cone becoming level with the base at a definitive temperature ...

The Standard Pyrometric Cone Company was founded by Edward J. Orton, Jr. in 1896. PTCR rings (Process Temperature Control Rings) were originally called "Phillips Temperature Control Rings" and developed by Phillips Electronics in Uden, Netherlands. The plant is now owned by Ferro and moved to its current location in St Dizier, France in 2010.
Flammability 2: Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38 and 93 °C (100 and 200 °F). E.g. diesel fuel code F: 3: Flammability 3: Liquids and solids that can be ignited under almost all ambient temperature conditions. Flash point between 23 and 38 °C (73 and ...
A typical temperature increase upon ignition of a cool flame is a few tens of degrees Celsius whereas it is on the order of 1,000 °C (1,830 °F) for a hot flame. [ 2 ] [ 13 ] Most experimental data can be explained by the model which considers cool flame just as a slow chemical reaction where the rate of heat generation is higher than the heat ...

This high flame temperature is partially due to the absence of hydrogen in the fuel (dicyanoacetylene is not a hydrocarbon) thus there is no water among the combustion products. Cyanogen, with the formula (CN) 2, produces the second-hottest-known natural flame with a temperature of over 4,525 °C (8,177 °F) when it burns in oxygen. [11] [12]
