ganja din, your posts and the info you gathered are really interesting ! you seems to be very well informed on chemical and physical extraction processes ! how do you consume herb or hash, through vaporizing ?
I liked the post you suggest using a hot bath to start decarboxylate acids and thc A so it improves the potency.
If i understood well, it also could be applied before the ice o lator process, making the ending product more potent ? a 3 hours bath at less then 38°C should do the trick ?
Did anybody gave that a try ?

…
Which substances will evaporate from resin below 100C ? Will you post or link the data plz
CONCLUSION
When preforming the thermal decarboxylation of cannabinoid acids in either the presence or absense of organic solvents in an open reactor, an optimum temperature at which the volocity of the decarboxylation would be high enough and simultaneous evaporation of neutal cannabinoids would not occur could not be found. Consequently, it is not possible in this manner to obtain an amount of neutral cannabinoids equivalent to that of the cannabinoid acids from which they were decarboxylated. ...
Classical cannabinoids (CCs) are ABC tricyclic terpenoid compounds bearing a benzopyran moiety (Fig. 2) and are insoluble in water but soluble in lipids, alcohols, and other non-polar organic solvents. These phenolic derivatives are more water soluble [AFAIK that's good] as their phenolate salts formed under strong alkaline conditions
In an earlt SAR study, Edery et al. (1971) postulated the need for a free phenol for cannabinoid activity.
For those who choose to vaporize, here's a helpful little list.
Enjoy!

Same as I’ve seen before the most of the known active and possibly co-active components of a resin have their boiling points over boiling water. And it doesn’t explain significant loss of resin during my attempt of decarb at temp of boiling water. There is some pix in my album BHO.
Because of very obvious reason I wasn’t sober enough to expertise a changes of quality but quantity was visibly decreased. Some substances were evaporated.
It doesn’t explain also HMK terpenes bubbles in BHO. He was probably quite sincere in the assurances he repeatedly gave. I do not understand how and why did terpens evaporate into bubbles.
Here by “resin” I mean a secretion of trichomes heads glands extracted with a help of butane aka BHO.… Loss of resin? What do you mean by resin? …
