ok, folks. hello again. quick update.
swim got his new half kilo. this time from a new batch. last time was a returned cod from the old batch which, i'm assuming, is the one everyone else was complaining about.
good news this time, though. all said and done, swim's yield was 2.25 grams. swim attributes any losses to his own failures, given that this was only his second attempt.
a few minor changes from the first attempt. started with powdered bark, and just did three quick acid soaks by bringing a pot on an electric burner to a simmer, covering, turning off the burner (but leaving the pan on it) and waiting a half hour before straining and repeating. also, swim came upon a small separatory funnel at the local university's surplus store and was able to wash the naptha with 1 x ammonia+baking soda, and 2xdh2o prior to freeze precip. crystals still came out a little yellowed, which didn't happen last time, but no big deal.
probably could have bolstered the yield a bit had swim not thrown away the used bark mush just hours before reading about marsofold's suggestion to go back over it with a straight to base tek. but oh well, compared to the 400mg he got last time, swim is just beaming. :D
i'd take pictures, but i don't have a camera right now. and in any case, you could just photoshop my last picture to add a yellow tint and there you'd have it.
there will be a taste test tonight. i'll let you kids know how it goes.
