Lots of techs and info on it. I’ll give you my pointers.
First off if it is for an edible or drinkable then it needs decarbed at some point. If for smoking some will de carb, most won’t. So being this is for smoking hash or vapor skip the decarb as you could always decarb the hash at a later point.
You can use dry material or fresh. I prefer dry myself. Get some iso alcohol. The strongest you can get. I use 99.8% iso fiber cleaning solution because I have access and it’s perfect. But 90-95% iso you should be able to find cheap.
Don’t grind material up real real fine just chop it up, break it apart, cut it up whatever just don’t use a real fine pulverized power.
Put in a mason jar half full or so of material and stick that along with all alcohol in freezer. Overnight is best.
Have another jar or container, strainer, cheese cloth ready for the pulls.
When all is ready and as cold as it will be take out of freezer and pour alcohol until it is just over the top of material. Put lid on. Shake for around 20-30 seconds but don’t shake real hard. Strain it through strainer and then cheese cloth into fresh jar. Don’t squeeze the the material or you get unwanted shit. Put material back in first jar and put it and alcohol back into freezer to re freeze 4-6 hours or so. I will usually do 2-3 pulls and the last ones are more on the 20 second side. The weaker the alcohol the longer the pull should be imo.
I filter the iso liquid a second and even third time to clean it up. You will lose some at first. Start with a wet filter wet with iso. And then flush some iso thru the filter after your done to get anything good still caught in the filter.
After you collected all you are going to pour your iso wash in a pyrex, put a fan on it or heat it up slightly with something other then a flame. I place mine on top of a crockpot filled with a little water. Your house will smell like alcohol so you want to vent.
After completely evaporated you can scrape with a razor blade but that is a pain in the ass. I usually turn mine into oil with coconut oil so I decarb the iso hash in the Pyrex in the oven and then put my oil on it and infuse it on low heat. If you are making vape juice I am sure you could put your juice in that Pyrex and I infuse it on low heat.
Fwiw my last time I did it I used some real sticky resinous blue dream bud and trim and got 20% hash by weight of starting material which is pretty much unheard of. I also watercure my material before I turn it to hash to take all the water soluble crap out for better flavor and cleaner edible.
Damn I didn’t mean to type all that
