Manufacturing processes
Hashish is made from tetrahydrocannabinol-rich glandular hairs known as trichomes, as well as varying amounts of cannabis flower and leaf fragments. The flowers of a mature female plant contain the most trichomes, though trichomes are found on other parts of the plant. Certain strains of cannabis are cultivated specifically for their ability to produce large amounts of trichomes. The resin reservoirs of the trichomes, sometimes erroneously called pollen, are separated from the plant through various methods. The resulting concentrate is formed into blocks of hashish, which can be easily stored and transported. Alternatively, the powder consisting of uncompressed, dry trichomes is often referred to as kief instead of hashish.
Mechanical separation methods use physical action to remove the trichomes from the plant. Sieving over a fine screen is a vital part of most methods. The plants may be sifted by hand or in motorized tumblers. Hash made in this way is sometimes called dry sift. Finger hash is produced by rolling the ripe trichome-covered flowers of the plant between the fingers and collecting the resin that sticks to the fingers. Trichomes and resins can also be collected passively through cleaning of scissors that have been used to cut the plant, or containers like a kief-box used to store it.
Ice water separation is a more modern mechanical separation method which submerges the plant in ice and water and stirs the mixture. Trichomes are broken off the plant as the ice moves, while the low temperature make the trichomes more brittle so they break off easily. The waste plant matter, detached trichomes, and water are separated by filtering through a series of increasingly fine screens. Kits are commercially available which provide a series of filter screens meant to fit inside standard bucket sizes. Hash made in this way is sometimes called ice hash, or bubble hash.
Chemical separation methods generally use a solvent to dissolve the desirable resins in the plant while not dissolving undesirable components. The solid plant material is then filtered out of the solution and discarded. The solvent may then be evaporated, leaving behind the desirable resins. As THC is fat-soluble, it also dissolves in butter, which can then be used for cooking (see hash cookies and Alice B. Toklas brownies). The product of chemical separations is more commonly referred to as honey oil, hash oil, or just oil.
