I've been working my way through 4 gallons of rue tea, somewhat on the periphery. Settling took ages so I ended up just leaving it be for a couple of weeks. In the next few days I'll have separated and washed the sediment and was planning to dissolve a decent-sized portion of crude harmala freebase in butyl acetate once it has dried off. Then I'll be replicating the citric precipitation at this larger scale using a citric acid solution. Updates when it's happened.
