Nice work there mate

How much starting material did you use?

Hard to be sure if anything will still be there or not.. depends essentially on which kind of acid you used. Melting points for a few are: picrate mp 169.5-170.5°; methiodide mp 216-217°; fumarate mp 152-152.5°

Eitherway, I'd add 1L of pH6 acidic water to the pot and get it to a low rolling boil. Stir the stuff at the bottom, ensure it all dissolves. Reduce to about 500mL and continue as you would have

Either that or just heat up the bowl until the residue goes oily again, then take the heat off and add some flour and work it in until you have a resin. Divide the resin up into approximated 200mg doses. Preload (30mins) with some rue and swallow
