Evap before freeze?

Migrated topic.

Is it advisable to let some naptha evaporate before the first freeze when doing the Noman tek? My kitten will have a collected total of about 400ml of naptha to freeze (2 jars of 50g MHRB, 4 pulls of 50ml naptha per jar), is this too much? Or does it not matter the first time around?
 
well what you can do is simply stick in the freezer already, get whatever comes off (considering some crystals do precipitate), and then evap that naphtha to a quarter of original volume and stick in the freezer again (or reuse the naphtha in case you didnt throw your mimosa soup away)

Hi endlessness,

What is your typical result when you do this?

What you do is put the naptha under a fan and leave it until it becomes cloudy, not fogged glass but actually cloudy to the point you cant see through it. THEN put it in the freezer. By putting un-supersaturated naptha in the freezer you are wasting time because the process will have to be repeated at least once to get the spice out of there.
 
SWIM is quite against evaporating. His naptha has never yielded >5mg after it was completely evaporated post freezer precipitation.

SWIM uses either escort fuel or ronsonol.

Also evaporation would risk oxidation would it not??

Not a fact but SWIM's experience

Peace and Love
 
Yes a complete evaporation leaves you with oxidised spice and all the plant oils and crap thats in the solvent so it should be avoided. Usually after a freeze precip there is no more than 150mg of spice left in the solvent but that still can be evaped a little then put back in the freezer to recover.
