Hey everyone so I made a semi stable slab using etoh, temperature fluctuations and vacuum. I got about 20lbs of nugs I’m about to run and I have a fairly good idea of what I want to do but I’m not sure if it will make me stable slabs. So I’m reaching out!
I have 190 proof food grade etoh chilling on dry ice overnight - my biomass is freezing in dry ice as well. Before my pour I’ll empty 4lbs into a canvas bag - put the bag inside a frozen 5 gallon bucket (frozen with dry ice) and begin pouring 3-4 gallons of etoh over the material. I let this sit until the bottom stops draining then I squeeze out the remaining material into another 5 gallon bucket and I start filtering. First course is 20um filter paper - quick and easy. Second is a mix of t-41/AC. I’m following @TheLostBiologist method except instead of soaking the biomass I do a pour.
Then I hit the roto and concentrate the solution - once concentrated I weigh my flask to find the weight of solution and I add 10x etoh to material. Again this is just Thelostbiologist’s method minus soaking. I’m curious what people have done post and wash to get stable shatter or diamonds. I’m currently not in a position to be able to afford a Closed loop system. And I have a bunch of biomass I can basically Experiment with but I’m super new to ethanol extractions.
