From what I know about this process so.far is that heating may pull more fats and oils then an unheated pull.

Ate you certain the higher yield isn't due to pulling more fats oils or other plant material.the non heated pull.

Also is the color of the DMT different between the two pulls?

And I'm kind of confused as to whether the total base soup was heated as well as the naphtha or did you just heat the napthta ?

I've read in other threads that a test was done, using a different tek however, one using heat and the other just at room temperature and the yield was the same. I'll look for the post I'm referencing, which was done using q21 lime tek.

Reason I ask is in my past extractions I've noticed those done using heat have pulled yellow DMT crystal , one actually had a layer of oily waxy DMT which had to be scraped off the dish after the crystal was removed. My extractions done using room temperature naphtha have generally pulled white spice.

Both were done with different batches of bark so yield cannot be compared in my results.
