Need help identifying mystery deposit in roto

[Thetetraguy]

I just posted something about this, i think celite is probably the culprit. I think prewashing is the next step in ultra pure extracts using powders

Washing/Prepping powders

Ive always wondered if the minty piney smell we get from baking the powders is from moisture absoprtion from around the factory or mine. What happens when u bake the powders dry, reintroduce distilled odorless water in a washing sorta sop, then rebake it. Does that eliminate the “CRC” smell completely? Has anyone tried it? Or perhaps wash it with a slight diluted mixture of common monoterpenes found in cannabis?
