justugh,
I've been meaning to reply on your thread to your "system" and talk of temps. I haven't because I feel like I a flaming you but honestly just want to help.
I am concerned about what you said you did. I am not a scientist. But I have made enough QWISO and RSO to know that you don't hit some magical temperature and all the solvent is gone. I am genuinely concerned that you are now vaping something that still contains ISO.
You said in your post that the stuff you got when you took bud post VG tincture and dumped ISO in. The you heated it to remove the ISO and mixed with your BHO/E-juice combo. But you said that the stuff with the ISO provides the volume. Either it still is mostly VG or you did not remove the ISO. IF the ISO was all gone, it would not provide the volume.
iso is what i listed at a set temp it bubbles ...........and will keep going until nothing is left as the amount of if decreases the temp of the liquids raises shine cooks from 187 to 210f .....at 212f water boils
VG boil is 554f....
Boiling point 290 °C (554 °F; 563 K)

so if u raise the temp of the mix i did (vg enriched 2 oz of bud ) all the vg i could press out was out it was just soaked material with 1 pint of iso
now buy raising the heat like that caused the iso to break up and move to the top and evape off..........i raised the temp of my stuff to 220f
at that point no bubbles at all so nothing was left but the VG of a temp 554 and the Oil that was left in the plant ...........before removing from the heat i stirred it causing what ever what left in it at the 220 temp to clump and release did this untill nothing came out ............sat it out of the heat and stirred it (mimicing that link snaps showed me ) until the temp was down to 160 ..............then moved it to candy mason jars and let the heat vacum seal it to drawl up any left over gases i did not remove ............it made a golden foam on top open the top blow on it 2 days later looks like the stuff in 0 vape pen from denver
edit........the stuff i used to test it the first day was drawlen from the lower coner with 1 ml pippette to skip the golden foam layer
