Close the lid very tightly and shake it as hell for exactly 30 seconds (more might result in more chlorophyll extracted, making the final product taste not as good, less might result in smaller amounts of the extract). Then pour everything through a sieve and through a filter into a jar (you may press the ground material in the first sieve to make it sieve though a bit faster). Yes, this part will be very slow, you will need patience, filtering might take 20-60 minutes.
Pour a little extra alcohol into the small jar to make sure there are no left-over trichromes remaining in it and pour that though the filters as well. Cannabinoids dissolve in alcohol (for example, it doesn’t dissolve in water, so we can’t use that) leaving behind “powerless” plant material of buds. Sieve filters the chunky plant material and filter further refines the liquid by removing the tiniest bits of remaining plant (you have to use sieve for chunky parts, since using only a filter will cause it to clog very fast and filtering process might take hours). Since all cannabinoids are dissolved, they are in a liquid state at this point. Coffee filter allows all liquids to pass through it but stopping any solid particles. Once filtering is over, you will be left with a jar containing a clear liquid with a green tint. You might ask, where the hell is my concentrate then?
It is dissolved into that alcohol, we need to remove the alcohol now. Pour jar’s contents into the plate or any other flat-surfaced container you have chosen. Pour a little extra alcohol into the jar to again make sure you don’t leave any trichromes in it. If you have a fan, then set it to blow into the liquid at lowest setting. Important notice: make sure you leave the evaporating alcohol in a garage/basement/a ventilated area, since you will be evaporating all the alcohol you used, which is flammable and slightly toxic. The evaporation might take between 12 and 24 hours. Once the evaporation is complete (there are not even the slightest traces of any liquid on the plate), grab your razor blade and a chosen container for storing the concentrate and gather up from the surface. I used a toothpick to remove gathered material from blade into a container. You should be left with some really nice gooey and sticky extract. (alcohol extraction method for marijuana) CHILLAX – CHILLed Alcohol eXtraction method for making marijuana hash oil by RadiantBlueLight. Interested in ultra-potent cannabinoid extractions? I've been working on better ways to extract cannabinoids from cannabis for 15 years so here's CHILLAX (CHILLed Alcohol eXtraction). Most cannabis extraction methods pull out too much green plant matter for good hash oil. Here's how to make the cleanest oil ever seen without using butane or expensive hexane. Depending on the potency of the cannabis, you may extract 20-30% by weight of what you started with. So for example, you’ll get about 4g from 0.5 oz of buds. Chill a bottle of high % alcohol overnight in a freezer. Bake cannabis in a preheated oven at 250° F for 30 mins to decarboxylate. If you're using your vape remains, you can skip this decarboxylation step. Crumble up the cannabis while it's in the coffee filter. Place the coffee filter containing cannabis open side up into the frozen glass.
Put the glass with cannabis in the freezer for an hour. Pour enough chilled alcohol into the glass to just cover the cannabis. If the alcohol starts to turn light green, end now and go on to the next step. Carefully lift out the filter and let the remaining alcohol drip back into the glass. Gently squeeze every last drop out the filter into the glass. Be careful, it's really cold and don't tear the filter. Pour this alcohol into a bowl and let it evaporate with or without low electric heat. Pictured here is 7 grams of California's finest dissolved in half a cup of alcohol.
It will end up being very sticky but you can do a lot with it at this point. Such as scrape it up and smoke it like hash, roll a bud in it for cannabis caviar, or mix it with butter for edibles.
