Hash rosin is made by using heat & pressure on dry sift or bubble hash made from dried and cured or fresh frozen material.
The bubble hash is then loaded into a micron filter rosin bag & placed on a heated press which squeezes the hash until it filters through the bag.
While hash rosin has recently become incredibly popular, it’s actually a fairly old version of mechanical separation.
If you have concerns over hydrocarbon extracts, solventless concentrates like hash rosin are a phenomenal alternative.
