SWIM has been attempting an A/B extraction with Acacia confusa root bark and has great success until it comes to retrieving the crystals after freeze precipitation. After suctioning the naphtha from the basified solution SWIM puts it in a glass jar, and lets the naphtha evaporate to about 70% of the original amount to super saturate it. From there, it is placed in a pyrex dish and plastic wrapped a couple times to minimize evaporation. After a day or two, SWIM filters the excess naphtha through a funnel with a coffee filter. Most of SWIM's crystals remain on the pyrex plate, so from there he turns the dish upside down and places paper towels to catch all the remaining naphtha that drips down. From there, SWIM turns the dish right side up, and allows it to sit for hours for further evaporation. (SWIM uses a separate freezer for this and is well aware of what evaporating naphtha like that can do to food).
SWIM doesn't understand what to do after that point. He has tried to scrape the dish, which resulted in the crystals and a goo coming together, which when left at room temperature evaporated about 80% of the mixture. What was left was a nasty brownish goo.
Should SWIM take the dish out of the freezer and let the crystals come up to room temperature? Should SWIM first put them in the refrigerator so the temperature change is not so great?
Any and all feedback is appreciated.
