Did a STB on 100 grams of acrb. Used heptane to do 5 pulls then left in freezer for a few days. This was just for sage keeping, not necessarily for a freeze precip but some crystal lattice formed. After a few days this tray was taken out of the freezer and placed on top of a fridge in a garage to evaporate. After all the heptane evaporated, there's white crystals on the sode of the baking tray and orange on the bottom. I'm guessing the white was caused by freeze precip and the orange from basic evap.

I'm wondering if the white layer of stuff on the side is a cleaner product than what isbon thr flst bottom of the tray. Any ideas?

The orange is from the evap.
You should have scraped & dried your freeze precipped spice before the evap.
The bottom layer would most likely have been white too
The orange can be cleaned up but it's smokable (you should recrystallize & do a sodium carbonate wash anyways just to be safe)

This is the first time I got white too!!!! Blah. I've been smoking orange and its been awesome but this is the only time I've got white to appear. I enjoy what I assume is a combo of NMT and DMT in the orange stuff.
