Unfortunately SWIM does not get anything to drop out at room temp that stays. Only freeze precipitations work. The pics here are from the pull that was put in a pyrex baking dish. Most xtals would stay suspended in the naphtha and not stick to the sides. So it was decided to be poured into a mason jar and from there they sank to the bottom but will not attach to the jar. Whats the best way to get the xtals without losing anything?
On a side note...doesnt the first pic look like Xibalba in the climax scene of the film The Fountain? Thought that was pretty awesome!
I had a very similar issue with the crystals not wanting to stick to the jar as well. Here is what I did...
First you have to put a plate or dish in the freezer so that it gets nice and cold like the jar with the goodies in it.
Then once you have said plate nice and cold you pull out the jar and decant it very carefully to get the top layer of naphta out leaving the slush. At this point use a spoon to push the slush back into the jar and try to get that last little bit of clear solvant out without letting the slush get passed it. You have to do this quite quickly or the solvant will start to heat up and re-absorb your precious crystals. Now quickly take out the plate from the freezer and poor the slush onto it. Recap the jar and throw that back into the freezer upside down so that the last little bits of solvant can be taken out without stealing any more crystals. At this point you should be able to use the cold plate and spoon to separate the crystals from the solvant by just tilting the plate a little bit and letting the solvant run down. All of this has to happen quite quickly or the crystal in the slush will de-solve. Get rid of the last couple drops of solvant that accumulate away from your now more visible crystals and toss the plate back in the freezer at a slight angle to get the rest of the solvant to drain away. You shouldn't have too much solvant left at this point so hopefully your freezer won't stink too much. At least mine didn't that I could tell. Leave it all there for ten to fifteen minutes and you should end up with some very nice usable stuff! :thumb_up:
