From 10 g into 100 mL boiling acetone to half FASAd and the other half MASAd, then the small crystalline precipitates were collected and acetone washed-decanted at room temp-many times until acetone was no longer turning yellow. The final dry yield of the tan-light brown materials were 56 mg fumarates and 80 mg malates. That`s 136 mg out of 10000 mg, 1.36%. Great yield for a pilot experiment. There was probably more 15 or so that was lost due to minor accidents and voluntary tasting. Smell is wonderfully DMTish, but the taste is not quite as bitter. Active, for sure.
Few big leaf-like crystals would easily form on a conical bottom tube, but on a flat bottom tube it formed more numerous but smaller grains (not powder). All in room temperature. The left over acetone was left on the freezer with maybe some insignificant powdery stuff that dropped.
Images are the MASA material only and them both collected into tubes, fumarate on the left, malate on the right... a bit more flakey and subtle darker tinge on the malate.
Thank you, kind participants of this thread!
