So I ordered 6 cans of Colibri Premium butane in preparation of doing a BHO run. I think I'll end up using 10g of bud and probably a can/can and a half of butane. I plan on doing it the long soak method for a nice hour and forty five minutes. My question is about winterizing it though. Should I do that directly after the spray and filter? Or do I do it after the purge? Also how much everclear/99% ISO do I add? And correct me if I am wrong but the process is, add the EC/99% and then place it in the freezer for 24/48 hours, pour threw a coffee filter then purge again?
first of all, I would buy 2 brand new, clean, same size pyrex dishes from wal mart for like 15$. and clean a nice spot in your freezer or maybe set up a dripping device if youre running larger amounts.
as seen in the dish above, I evap all the butane off, outdoors, then scrape it up, weigh it, and drip it into my small pyrex cup.. I also get the dish warm with a quick blast of my torch, then pour everclear (careful as this shits flammable) into the warm dish, and it helps dissolve the oil into the everclear a bit faster, you can stir it too to help. takes about 5 minutes.
or like fadedawg said, you can mix the everclear while there is still liquid butane remaining, but ive never done that so dont know the proper technique so wont comment.
either way works though and your winterized stuff will be awesome.
as far as the amount, I usually do 10x the size of your oil glob... start small and add more if needed. I poured too much in my dish the other day and figured it was too much... really should have poured some back but got excited and threw the oil in right away so it was too late
not sure what the negatives to this would be though. you want it to be the consistency of alcohol still... if your oil is making it thicken in the pyrex, add another liquid ounce of everclear.
let it freeze for 48 hours. im not sure if 24 is any different than 48.
clear a nice spot in your freezer. set your second pyrex dish up in the freezer, and either set a filter into it, OR hang a filter off the freezer rack with some tie wire, or build something fancy if you want. you want to try to keep the mix COLD while dripping, so try to do it IN the freezer. pour it, and forget it. try not to go over the half way mark in the filter, and do not shake it or agitate it to get more juice through. do not squeeze it when youre done. when the filter is dry, stuff it into your butane extraction tube to prevent weed crumb blow back, and the butane also rinses that everclear oil that stays in it.
to evap it, however you normally do, either in a pyrex dish or a stainless steel bowl, set it on a griddle OUTSIDE on very low heat, and place a fan on it for a few hours.
scrape it up, drip it onto parchment paper, throw it in the vac chamber for 12 hours, and youve got yourself the nicest, smoothest chunk of amber glass ever. youll love it and be addicted, I cant even smoke non winterized oil anymore, its so fuckin harsh!!!! ive spoiled myself with this winterizing stuff. only problem is a half oz gave me 2.5g of butane oil... and like 2.2 or 2g of winterized oil... ouch!!! worth it though, you only got 1 set of lungs and those plant waxes DAMAGE the lungs. youll understand after you winterize.
