The usual process from the handbook is to freeze precipitate and drip dry while in the freezer. This is all fine but when the bowl is taken out and the fan turned on some condensation forms and this water pools at the bottom of the bowl, partially disolving some spice and generally slowing everything down because water takes a lot longer to evap than shellite. Any suggestions for swim?

This is a funny one, sometimes it would work fine and other times this would happen. Best way to combat it I found: Take out of fridge and pour off solvent straight away, put the 'lid' back on your bowl (foil and rubber band works good) then put it back in the freezer but upside and leaning to one side to pool all the excess solvent, take out after an hour or more and carefully pour off remaining solvent, then put upside leaning to one side on table with the fan pointed at it best you can to keep the air flow, keep it there for a while and hopefully if there is any condensation it will drip onto the table, when it seems relatively stable put it upright and under the fan till no scent is left.

Very good ideas. Swim thanks you both.
