No argument from me. What I do know is the band heater type using high heat with a sealed top does build up a certain amount of pressure The 1/4 . inch tube allows this pressure to escape, just as a radiator with a hole in it may do when you see steam coming out. One difference is an overheated car probably never reaches 230C? I am no scientist or chemist, Perhaps you are correct. Perhaps you are not. I am stating what Randy Oliver, whom I have much confidence in, as do many others throughout the world. Perhaps he is wrong? Perhaps I am wrong for trusting him? My finding of this and sharing this, stemmed from Parks original question and concerns. From Parks concerns I ask questions here and did some searching myself and found the following by Mr Oliver. If you read closely he is banking on the CRC Handbook of Chemistry and Physics I have no more to add to this his finding that I have not already attempted to add in order to answer parks legitimate question. Perhaps if I were to search further I may be able to find more to help you and van? But it seems I am banging my head against a wall, if you will or beating a dead horse. lol .
"in the CRC Handbook of Chemistry and Physics we find that upon heating oxalic acid, the water of hydration boils off first, then at 315?F" (157.222 ?C) "the oxalic acid starts to sublime (go directly from solid to vapor), and finally at 372?F" (188.889 ?C) " any oxalic acid which has not yet sublimed decomposes to formic acid and carbon dioxide. The hot vapor rises within the confines of the hive bodies, and recondenses into tiny crystals that coat everything inside the hive. One of the problems with some vaporizers is that they get too hot too quickly and decompose, rather than evaporate the acid.
