Vaping BHO with a Heatgun Glass Pipe? (best temp)

I have a old Headgun Glass Vapor Pipe. I was thinking it would be cool to use it for BHO, with a digital Heatgun that you dial in to a exact Temperture. I have seen online that THC boils at *392 F. So my question would be what Temp do Concentrates Boil/Vape at?

Different components in the concentrate will start boiling/evaporating at different temperatures.
Personally, I'd start with temps between 375f-450f.

Here is a partial list of the active components in cannabis and their respective boiling points:

Agreed, also depends on your goal. Lower temps seem to affect mind more, higher temps seem to affect body more, all in relation to strain, harvest, dry, cure, age.
