Sorry for the lack of details.
SWIM was at a friends house, and had brought a little of the freebase with him... A few hundred miligrams was put in a test-tube, with a little denatured ethanol, and concentrated (32%) AA (the only acid SWIM could find in the house
) was added, until the freebase dissolved in the alcohol...
It was then poured onto a plate, and evaporated in the oven.
No recrystallization was done, since time was a factor in this particular case... (Crashing would probably had worked, but SWIM wasn't sober
)
