Update:
The
afore depicted HCL acidified solution was filtered.
Inspired by
this technique, equal amounts of acetone was added to about 250ml of the solution. (The remainder of the solution was previously basified to see if anything would precipitate, but was unsuccessful. It will be re-acidified.)
Nothing occurred, but did not try refrigerating. (Will try next round)
Added salt until no more would dissolve. A mild fizzing reaction began to occur, and once this stopped the solution was placed in the fridge.
*15 mins later, there is a layer of fluffy tan/whitish precipitate gathering on the bottom*
Whether or not a difference was made with the addition of acetone is not known. Side by side tests will need to be done to see.
Also, I do not know if the A/B/A step (which resulted in massive dark precipitation, assumed to be impurities) assisted in allowing more to precipitate.
A new brew is boiling down to continue experiments.
All the above is in assumption that the precipitate is indeed harmalas, though it looks positive!
