Id say the above answers to your questions are correct
If you want shatter what you want to do is get at least 190 proof, and do the extraction at freezing temp. I get a bath of alcohol mixed with water and leave it in the freezer with the alcohol i intend to use for the extraction and the prepared bud for at least 24 hours but preferably a couple days before starting.
Everything out of the freezer, pour the 190 proof in with the bud, just enough to cover it. Poke it around with a new chopstick. Put the jar in the freezing bath. I then set a timer for 15 mins and set this in a cooler and the alcohol back in the freezer.
During this time i prepare my french chinos strainer, and a buchner funnel filter with a hand pump.
About 20 seconds before the timer goes off i cancel it, grab the alcohol out of the freezer, take the jar with the bud mixture out of the cooler, wipe it off with a towel to get all the liquid off of the outside, and strain it through the chinois into the buchner funnel. I then take some extra alcohol and pour it through the bud to wash out the remainding oil. . Once its pulled through the buchner funnel filter its left with no particulate. I evaporate in a warm water bath around 110 degrees with a screen rubber banded over the evaporating dish to prevent crap getting in and a fan blowing over. Some strains will wax up at 110 but as long as the water baths 110 the actual dish isnt. You want to let it sit for a day or two after it seems evapped to really let it harden up.
I recommend grinding the material. Most say this is bad but i ran a test grinded vs scissor cut and grinded only yielded more with all other variables the same.
The only reason i use the cooler as opposed to putting it back in the freezer is because i cant stand up my quart jars in my closed freezer.. too much shit lol
