ISO Question

[2clicker]

ive been reading in the oil extravaganza thread and it has me wondering about purging.

is a second or third purge recommended when extracting with ISO? i use a water bath to evap ISO... should i do an oven purge after that? will the ISO react like butane when oven purging? will it bubble so that its visible that something is happening? after purging is finished will freezing the oil make it easier to handle?

sorry for all the questions. learning a lot in here

heating helps, freezing helps, if ya wanna really get it pure you can rewash with eth then vacuum filter and vacuum purge. as for handling i find heating just to a liquid then using an amber dropper bottle works best with shatter-like oils. it will re-harden in the bottle.
