Hey there, sorry for the lag.
It goes solid enough at 10c/50f to stick to a metal utensil. This way, you just have to poke the oil with metal and drag it to the walls of the boiler, then dump the waste water. Colder the better, but 50f is the highest for handling the oil.
Thats fine. I assume you are distilling without water. With only alcohol, you can stop early, then put that solution in the freezer to dewax. QWET works but takes too long to freeze that amount of alcohol. If you do two 1 minute high agitation washes at room temp, then boil that down to a cup of alcohol, you can then freeze this in an hour rather than 12-24 hours. It will speed up making oil. The waxes survive the distillation. You're better off freezing 1 cup of alcohol rather than quarts or gallons.
