1) Dry sift. Not so clean I guess
2) I have a 10 ton press with aluminium heating plates. I press the hash using 37micron bags for 60seconds at a temperature of 80 celcius and a pressure of 500. What is left behind is some dried sandy textured darker hash that is not smokeable.
2a) the rosin...
So if I have some rosin made from hash, should I just make distillate some cannabis to get the essential oil and mix it with the rosin? Or is there another process to separate the terpenes from the essential oil and then mix the terpenes with the rosin?
