vhGhost said:This is the way i make oil ... it is a very quick rinse method, with 3 different rinses.
First i prepare the popcorn bud by busting it up, but not to a powder.
Busted up and ready for the freezer
I don't find that it takes to long in the freezer if its spread out really well, Plus the iso also gets the freezer treatment, i will only use about 750ml of iso this run.
These are my basic ingredients
2L pop bottle cut down - this way i can move the bud around easier and not have to mess with it
The first 2 rinses should only take as long as it takes to drain through. About 250ml per dish.
First rinse
2nd rinse
3rd rinse is a bit different, by now the bud has been in contact with the iso for no more than 1 min(2dishes). So what i do is take the bud out of the filter and into a masson jar filled with 250ml of iso. Then i shake the jar like crazy for about 30-60sec, and drain through the coffey filter for the 3rd rinse.
I use a rice cooker and it holds my pie plates perfect. And i DO IT OUTSIDE

Rinse 1 finished - i left it just a tiny bit oily unlike the 2nd rinse
Rinse 2 finished - This turned into chrystal, scraping this was interesting( my thumb was covered in sparkly goodness
Rinse 3 finished - well this 1 i kept oily so that i can store it in a vile.
And the finished product. Vile 3rd rinse, bottum 2nd rinse, top 1st rinse.
I like doing it like this, and in the future i might add another 250ml of iso and another pie plate, just to see how much more is wasted.
I hope you all enjoyed my way of making oil( well not really my way ) just my experience.

like if you evaporated most of your IPA in a pyrex dish, and then put the dish on a hot plate, boiling pot of water, etc and kind of stir the oil around for a while
be careful though. once it cools, it will shatter when you scrape it
