I know of (and have done) the mechanical separation method but I can not find much information on the rosin jar tech (see rosin.ryan om instagram). From the comments he has answered I think he presses at 220° then collects into mason jar, then places in toaster oven at an undisclosed temp for an undisclosed amount of time, (then maybe its stirred and re-sealed?) then it is placed on a clone/heat mat at an undisclosed temp for a couple days. The end result is terpene seperation and THCA Crystals grown just like a solvent extract. Can anyone clarify some of these steps for me?
I believe @diet.funk on instagram breaks it down a bit more on his page and he’s usually real nice with answering questions. Hope that helps!
