For memory the EA stayed red after freezing precipitating the harmala. This wasn't crude harmala extracted EA. It was with already purified harmala that was then dissolved in EA to test freeze precipitation.
Thanks 😊
I'll earmark a sample of freebase solution for temperature cycling tests. It seems the reversible colour change displayed by my initial test precipitate was a peculiar anomaly.
On further examination of the CASBA-CIBLO precipitation it appears that the primrose-yellow suspension aggregates to form dirty orange masses as the solution settles. Much as one might expect, settling is more rapid with the more concentrated fraction.
Speaking of settling, I just decanted the solution of re-acidified freebase that fell on the floor. Despite slow filtering through a generous cotton plug, there was a couple of milimetres thickness of black 'harmala crud'â„¢ sat at the bottom of the jug. This kind of highlights the value of patience in harmala extractions as this has had over a week's settling time. I'll be leaving the decanted solution to settle for a few more days to help clean that up - something any home winemaker should understand.
PS - thought I'd best mention, the repaired microgram scales turned out to be way off in the calibration tests, not to mention lacking stability. I'm still restricted to centigram resolution until this gets sorted out.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
