Ice Hash is also more commonly known as Bubble Hash, Ice Water Hash or Wet Sift, just to name a few. Ice Hash is a cannabis concentrate that is formed by sifting the trichomes of the cannabis plant in the presence of ice water. This is considered to be a contemporary form of hash making, and just like traditional hash, it can be crafted mechanically or by hand.
The primary objective in making Ice Hash is to separate trichome glands from all other plant components. Trichomes produce and retain the plant’s cannabinoids, terpenes and other such molecules. They are the glandular appendages on the surface of the cannabis flower. By the removing of all the contaminants, there will be no barrier between the user and their trichomes experience.
First popularized in the 1980’s, the techniques implemented in making Ice Hash was done by a cannabis industry seed expert pioneer David Watson. Through some trial and error, eventually it was learned that resin glands sink in water. Soon the wider cannabis market was introduced to a hashish making process of stirring the entire cannabis plant or sieved resin in water.
This water-extraction process opened a path for the first automated sieving machines incorporating other new techniques for ice-water extraction in its development. Then in the 1990’s, Canadian Marcus Richardson made his contributions to the water-extraction methods which ultimately revolutionized the hash realm with the “Bubble Bag” extraction system.
All throughout the 1990’s, Marcus Richardson was highly active in the advocacy of medical cannabis including the development of cannabis extraction and decontamination. Through his efforts, the water extraction method gained popularity with the first multi-bag filtration kit arriving in 1999. The three bag design filtered glandular trichome heads producing a safe and most efficient method of delivering cannabinoids, and exploring the limits of this Ice Hash extraction method.
Use of Term
I really like that we don’t have to use any solvents to make this ice hash.
