The person that does the extractions I've had has a dead simple method.
He does two ReX's.
1) Re-dissolve in Naptha and puts a fan blowing over it until the solution just starts to cloud up and then tosses it in the freezer (covered) for a few hours....or over night. Then filter and save the NP for the next pull. Honestly I doubt it's necessary to use the fan, but he likes to do it that way as it speeds things up.
2) Re-dissolve in approximately the same amount of fresh solvent as you just removed it from. In this step you can heat it a little to get it all into solution. Then place on the counter (covered) until room temperature. Then put in the fridge (covered) until fridge temperature and then toss in the freezer (covered) over night.
When removing from the second ReX he likes to knock loose the crystals and then filter with a handheld vacuum filtration device. The remaining crystals can be captured by letting the ReX vessel fully evaporate.
The spice he generates usually has two qualities. The bulk is pure silky white and comes from the crystals that were knocked loose and captured during filtration...and the second, minor product, was captured after the remaining NP was evaporated from the dish....this minor product has a very slight tint of yellow.
so if I understand it right first rex is done with room temperature naphtha ( how much ? ) just mix it and put in freezer then filter with coffee filter ? leave the spice in the filter to dry out ?
what I do is to remove naphtha and take all the spice out and put it on glass and leave to dry out.
then second rex he used hot naphtha right ? and than leave out till temp down , then fridge ... and freezer
