its super super easy
just take a mason jar ... i grinded my trim and small buds ... throw it in the jar
pour in your iso alcohol ...(get the 91% they have it everywhere) but 70% works too
put the cap on the mason jar
i let it sit for a bit ... then shake it for 20-45 seconds
strain off the plant material dont let it get into the pyrex dish
pour the alcohol contents into a pyrex pan or any dinner dish the flatter the better
put the pyrex over a boiling pot of water
and evaporate the iso off until its all gone
and then start scraping like a mo fo
roll it into a pretty little ball
and smoke that shit
and you just made some iso hash
