Ignition temperature glass

The figures for flash points are closed-cup values except where a suffix (o) indicates the (usually higher) open-cup value. The figures for explosive limits (or flammability limits) are % by volume in air at ambient temperature except where indicated otherwise. Where no figure has been found for the upper limit, a query has been inserted. Figures for auto-ignition temperatures are usually those determined in glass (without catalytic effects) except where stated. 

The temperature of ignition of a mixture fired by adiabatic compression Is lower than when the same mixture is fired by being heated in a glass or silica tube at atmospheric pressure. Professor H B. Dixon in a private communication to the author states that he found the ignition temperature of electrolytic gas under the latter conditions to be 580° C. 

It is a fact of experience that the inner surface of an electrically heated glass flask with a delta-shaped longitudinal section shows the lowest temperature limits to start an explosion. This temperature, Tir experimentally determined as stated in IEC 60079-4, is the lowest value of the total range of experimentally determined ignition temperatures by varying the concentration of the... 

It does not drip and the char Is black and glossy. The UL Ignition temperature of the 40% glass-filled resin Is 540OC.
