How to Make Your Own THC Diamonds Using Solventless Separation

Mechanical separation, or fractional melting in this case, is a method of using heat and mechanical force to separate a substance into its constituent parts based on their differences in melting points. Because terpenes typically have much lower melting points than cannabinoids, it’s possible to use heat to melt just the terpenes, and then with the appli ion of a little mechanical pressure, you can squeeze them away, leaving behind an incredibly pure mostly THC powder.
