Hash or Cannabis

Hash oil is a concentrate of hash or marijuana (cannabis oil) that has been dissolved in nasty hydrocarbon solvents such as ether and alcohol to extract the THC. Hash and cannabis oil frequently retain residues from solvents used to extract the THC These residues are a health risk. The oils can be very concentrated and potent.

Honey oil was somewhat popular in America in the early 1970s. The oil was a translucent golden-amber color. The oil transformed from stiff, toffee-like consistency to runny oil when warmed. Cannabis oils are normally dark in color because they contain chlorophyll and other contaminants. Filtering the oil through mm


charcoal will remove virtually all of the impurities.

Hash oil never became super popular because it is inconvenient to smoke and many users do not want to be exposed to the health risks associated with the solvents used for processing. There are many safe ways to separate the THC-potent glands from the foliage.

The oil can be wiped on joint papers, cigarettes, pipe screens, hot knives, etc. A popular smoking method is to smoke it tn an oil pipe, a stem with a glass bubble on one end. A little oil is placed inside the glass bubble. When heat is applied, the THC vaporizes and is inhaled through the stem.

Volatile solvent extraction

We do not recommend volatile solvent extraction because it requires the use of dangerous chemical solvents such as isopropyl alcohol, ethyl alcohol, and white gas.

Cannabis is soaked in the solvent, and the solvent is removed by evaporation. The resulting residual is a sludge that contains chlorophyll, plant waxes, other debris, and cannabinoids.

Isomerization is a chemical resin extraction process that was very popular in the 1970s and early 1960s. The process has fallen out of favor because of the harsh and dangerous chemical solvents-white gas, sulfuric acid, hydrochloric acid, etc-used in the process.

Butane cannabis oil is made by passing butane gas through chopped cannabis. The butane dissolves the THC and transports it out a drain where it is collected. The captured butane contains THC. The butane is evaporated away by setting the collection container in a pan of warm water. Once the butane has dissipated completely, the residual honey-colored oil is scraped from the bottom of the collection pan.

Butane hash oil is dangerous to make because the process involves using a quantity of butane in an open container. The fumes are toxic and a small flame or spark could cause the butane to explode. People who make butane hash should make it in a well-ventilated or outdoor location.

Jelly hash is a combination of high quality hash and cannabis oil made from butane extraction. The typical recipe contains eight parts hash and one part cannabis oil (AKA hash oil) usually extracted with butane. Although very strong, the dark jelly hash has a characteristic sticky, oily consistency which makes it difficult to handle.

Gold, Ronin Press, and, of course, on wvwv.oye rgrqw.com. Pressing Hash


Once collected, resin powder is often pressed to facilitate handling and storage. Bulky resin powder is awkward to handle. It is easily spilled, blown away, and contaminated by dust and dirt. Resin powder is also more difficult to smoke, especially if no screen is available. Once pressed into a piece of hash, the resin is easy to handle, store, transport, and consume. Proper pressing is essential for storage and to slow decomposition.

Pressing ruptures resin glands and warms the resin, causing many volatile aromatic terpenoids to release their aromas and flavors.

You can press the resin powder by hand or with a mechanical device. You can elect to add heat, a drop or two of water, or alcohol while pressing to make less-pure hash stick together in a block.

Mechanical presses must be precise and align well so pressed hash does not ooze out seams. When pressed, heat and friction cause the outer layer of pressed hash to oxidize and turn darker than the interior. In fact, hash can have a dark exterior and a blonde interior packed with creamy resin glands.

Make sure to pre-press water-extracted hash in a piece of cellophane to contain it and help

Continue to knead the resin in your hands until it forms into a solid shape.

Now pressed into a wafer, the piece of hash will be easy to smoke and will burn evenly.

Press the resin into a wafer. Check out this compressed resin powder. You can see the resin glisten!

Remove a few clumps of water-extracted hash from the glass cone.
