To me the extract reminds me of DMT that has crashed out very rapidly, forming many small crystals and being less stable in heat. It has the appearance of not being fully dry or waxy. I've also seen layers that I thought were fats but they turned out to be just DMT flocculating together. The clearer the solution the easier it is to see this.

Personally I would have weighed and vaped some to see how impure it actually is (or isn't).
