Yeah, def not accurate, more like ball park figures. Plus size of dab, even a tiny one is gonna change how the temps situation works.
Im just surprised that I'm getting similar results, findings, blah blah blah, along with back where I started - using the number dial on a non digital volcano and checking what temps each setting was roughly supposed to be and how that knowledge changed my usage when filling the bowl completely, how that effected my lungs, breathing, phlegm production, recovery time, and of course, coughing.
Obviously, in the dabbing world, theres the added complication of the carb cap and the pressure drop, the inhale swap of air blah blah blah too
Everything changes up again, and dish temp readings taken in the open air go back to being potentially useless info
However!
This is all still pretty roughly lining up. I can do small enough dabs at 350f dish temp of mechanically separated thca, and have the whole dab evaporate. Even with terps, and a 'normal' rosin dab, the whole dab will be finished at 415f dish temp. If theres the gloop from terps left over in the dish, going higher in temp just brings out a vile taste, then that carbon taste starts at ~460+. So now, with thca at hand, finally being able to mix my own ratio, I can add more hit, not increase the dab size too much, and have even lower temps. Now you saying that 500f terpene burning temp, and how were playing with inaccuracies and increased temps when capped, it lines up with 460f dish temp maybe being the start of 'too hot'.
Obviously, I realise this is all riddled with subjectivity and variables of room temp, air temp, glass type, inhale speed etc etc. but this is all lining up with (of all things) my no cough massive bowl temp stepping on the volcano, and then on every iteration of the flower pot. Now here with dabs on the tbucket, aided in my settings by you mentioning the speed of coil/dish reaction time.
I think part of what Im finding is that the cleaner the rosin, the more obvious it is that this is happening, and the easier it is to temp step thru it all thanks to the coil/dish reaction time.
My lungs havent felt this good in years.
