Rosin, also called colophony or Greek pitch (Latin: pix græca), is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components.

In polymer chemistry and materials science, resin is a “solid or highly viscous substance, usually containing prepolymers with reactive groups.” Such viscous substances can be plant derived or synthetic.


What is Rosin?

Rosin refers to an extraction process that utilizes a combination of heat and pressure to nearly instantaneously squeeze resinous sap from your initial starting material. The term “rosin” originated as a method of making a product used to lubricate violin bows. With cannabis, this method is incredibly versatile in that it can either be used with flowers or to clean up hash and kief into a full-melt hash oil. The result is a translucent, sappy, and sometimes shatter-like product. If executed correctly, rosin can rival the flavor, potency, and yield of other solvent-based extraction products.

So there you have the basics. Squeeze your bud and the stuff that comes out is good. So now that you know what it is how do you get it? Let’s start low tech and work our way up. Pressure and heat. It just happens that a hair straightener will provide just about the right heat and the human body can provide enough pressure to do a reasonable rosin extraction on most cannabis buds.

Get some baking paper, a cheap IR thermometer, a Hair Straightener and some weed. The better the weed the better the results.

A little more in depth version…

Now, I know a few of you won’t be happy with the yield and the labor involved, so Dabber Dan has the solution for you, the Rosinator !!!
880PSI through a 20 ton jack. If anyone in the MatSu wants to get into industrial Dab production via this method I can get you the hook up on ready made or custom presses, Kief bags press plates and Rosin receptacles. Just drop me a line at and ask about Rosin Presses.
