Burning THC

This is a second lab I ran that burns THC. I used third run and substantially isolated D9 THC. The instagram engine chopped off the top part of the vid but the important visual data is shown.

I have no idea if this is an accurate data point as measured but it at least confirms the minimum temperature that can be seen when D9 THC combusts. I am curious now how CBD would combust and at what temperature?
