I was an avid bubble bag user but could only achieve full melt on specific strains and then i purchased a ecig vape that took only oil. so i finally bit the bullet and dove into ISO extract. I felt very confident in its safety as i am big on organics and no chemicals. here is the way i do ISO extract to make my hash oil (which ends up like a piece of caramel taffy, not too sticky, able to be handled at room temperature, and bubbles and melts clean when heated)
First things you will need:
ISOPROPYL alcohol. 91% or higher. 91% is ok during warmer summer months, but if the weather is cooler use only 99%. and it HAS TO BE ISOPROPYL. do not use rubbing alcohol or everclear or any other type of alcohol you think is better.. it is not and it is also not safe.
A stovetop glass coffee pot.
A Metal screen coffee filter that goes on top of the pot.
Standard paper coffee filters.
A clean pyrex bowl dedicated strictly to hash.
A splash guard (big circle metal screen) to place on top of the pyrex bowl.
1 large mason jar
1 plastic tupperware container rectangle shaped
Razor blades
An electric oven
a metal screen strainer
....
First step is to get your ISOPROPYL alcohol. I buy mine from CVS if im using 91%, they have big bottles there.. if its a cooler time of the year i just order 99% from amazon.
place in freezer for at least a couple of days before u are going to make your extract. THIS IS CRUCIAL DO NOT SKIMP ON THIS STEP.
place your trimmings in the freezer also for the same amount of time.
..
When you go to start making your extract, place your trimmings into the mason jar, when the jar is full (or you are out of product) add the alcohol. i usually fill about 90% of the way with alcohol. usually about 2 big bottles of ISO.
Put the lid on the mason jar and turn up and down and around and shake for about 30 seconds.
take the lid off and pour through the metal screen strainer into the plastic tupperware container. basically u are seperating out the alcohol from the plant material at this stage.
throw out the plant material, rinse out the mason jar, and fill the mason jar with the alcohol now seperated from the plant material.
go outside (if you arent already) and set up your coffee pot with the metal coffee filter, then place about 10 paper coffee filters on top the metal one. proceed to pour the alcohol mixture from the mason jar into the top of the coffee filter. it is going to drip slow, so have patience, just pour so its all going into the paper filter, and leave it alone for about 15mins, then go back and top it off.. repeat until all your mixture is thru the filter.
now u will have a very light neon green color liquid in your coffee pot, compeltely clean of any plant material and BS. just pure alcohol and cannaboids.
pour this into the clean pyrex dish, leave it outside with the splash guard on top of it to prevent anything from flying into it. u can place a small fan next to it blowing down into it to speed up the alcohol evaporation process. do not use heat to speed up the process this is dangerous. also do not do any of this near an open flame or anything that can spark.
during summer heat it will all evaporate usually within 24 hours. if u are using 91% in winter temperatures it can take upwards of 5 days to evaporate (the alcohol will go, but the 9% water will take forever, this is why in cooler temps use 99% ISO).
once its all evaporated u will have a compltely dry pyrex dish with residue all over the bottom and side walls.
get a razor and scrape it all together, it should be a light color looking like maple sugar or sand. it will be sort of powdery at this point. scrape it all free of the pyrex dish and into a neat pile in the middle of the pyrex bowl. preheat your oven to 150-200 degrees and give it about 3-5 minutes in there. what u are doing is heating the oil just enough to melt it together, this is not a decarb for eating it like rick simpson oil, its simply just to melt it together so it will be easier to handle later on.
pull it out, and the oil will appear darker now, almost brownish. it should look melted together almost. get a razor and scrape it together again and itll stick together, swirl it around a few times with the razor and it will lighten up a little.
once its swirled together and looks oily, let it sit out for a bit to cool off. once it cools off i will harden a little and if u slide the razor under it, it should pop off easily and be fairly easy to handle.
at this point u can smoke it however u choose. i personally load mine into a ecig style vaporizer . but u can put small little shards on top of a bowl. the oil will bubble and melt away cleanly. extremely potent and flavorful. I have people who are avid ear wax smokers comment on the flavor and high of this extract and if they hit it out the ecig they cannot tell the different unless i mention it to them.

I'd do this and interchange the ethanol for the ISO. I'd dry the ever clear with anhydrous magnesium to get near pure ethanol or near pure ISO.
