Although scientists have good reason for using the metric system, Ozark Americans like myself are firmly rooted in God’s Own Imperial Measurements.
America fought and won two world wars so we’d not have to use the metric system, but I digress.
I was curious as to the temperature of the burning cherry in a pipe, and official do gooders have calculated the average temperature of a burning pipe at 500 degrees Celsius, which is about 950 degrees Fahrenheit.

Summary
The temperatures produced when tobacco was burned in pipe, cigarette, and cigar smoking have been measured by a calibrated thermocouple.
Temperature of the combustion zone in a pipe was about 500° C. (variability, 380°–620° C.). The maximal temperature was thus relatively low, but the heat spread over an extensive area outside the actual glow. Because of this, strong dry distillation took place, and the corresponding fractions from the evaporating substances escaped into the smoke without being pyrolyzed. With a cigarette, the situation was found to be quite different. The temperature was high, averaging 650° C. (variability, 470°–812° C.), but over a very limited area. The amount of dry distillation was slight, and the low and middle fractions were burned more completely. No essential differences could be noted among the different brands of cigarette studied.

Most hillbillies know that the average flash point of wood is about five or six hundred degrees Fahrenheit, so briar (and corn cobs) must have a higher flash point, to stand the abuse of repeated firings of nearly a thousand degrees Fahrenheit while smoking a pipe.
When you can taste and smell burning briar in a new pipe, you’re on the razor’s edge of burning up your pipe.
After you’ve done your part to break in your pipe fully, by smoking it all the way down until all burning briar taste is gone, and there’s a black, resinous deposit completely coating all of the chamber, you’ve somehow increased the insulation value of the pipe and you’ve raised the flash point to well over a thousand degrees Fahrenheit.
If you proceed further and start building up a true cake of carbon in your pipe, then that cake adds to the insulation value and it serves as a heat sink,
It’s my theory based on experience, that until all the chamber, even to the bottom, gets a coat of resin or forms a cake, that the best flavor of the top part of the bowl won’t develop.
The exact, same phenomena makes food fried in a completely seasoned cast iron skillet taste better than one that’s not fully seasoned.
But a man should spend all his life, considering he might be wrong in his beliefs.
If I’m right, then why are used pipes smoked entirely down to the bottom so scarce?
9 out of 10 pipe smokers might be wrong, but I calls em’ as I sees em’.
