![]() | Found this floatin around, might be usefull... Since so much time, labour, and cost has gone into the production of each plant, growers do not overlook utilization of the "shake" or leaves. Extraction involves the process of removing the essential oil, THC resin, from the leaves remaining on the plant and those removed during pruning. This is accomplished through the use of a solvent in which the oil will dissolve, which is later separated from the plant material by passing it through an appropriate filter. The best solvent found to date is chloroform. It is non-flammable, which makes it safer to handle than ethanol. Further, it has a low boiling point (61 C., 142 F.), and a residue after evaporation of .0005 percent. This low residue percentage means that virtually no trace solvent remains to contaminate the oil and cause an aftertaste, which is usually a problem encountered with ethanol unless time-consuming distillation processes are used. Another important concern is that chlorophyll is relatively insoluble in chloroform, eliminating the heavy "green" taste that always results from ethanol extractions. To initiate the extraction process, the leaves must be dried thoroughly. This can be done by placing them on fairly absorbent paper, such as newsprint, in a good sunny spot near a window. (Fresh newsprint paper can be obtained in most art supply stores. The lead content of ordinary newspapers makes them unsuitable for this purpose.) The leaves are then turned over every few days to ensure complete drying. When they are sufficiently and completely dried, the leaves should be brittle and crumble easily between the fingers. They are then placed in a blender or food processor and ground to a fine powder. Studies have shown that to achieve 90 percent extraction of the oil, the plant material must be powdered. ["Studies"?! Don't ask... -ed.] This is because nearly as much oil is contained in non-glandular internal tissues as is produced by the glandular tri-chomes. Next, a filter (a coffee filter will do) is placed over a clean Pyrex beaker or Corning Ware dish. The plant material is piled about halfway to the top of the filter, and the rest of the material (if any) is saved in an air-tight container. Pour approximately 200 ml of chloroform into the blender or food processor and slosh it around the sides. This rinses out any oil that may have adhered to the container's walls. Chloroform is poured from the blending container over the plant material until it reaches the top of the filter (adding more chloroform if needed). When the chloroform has completely filtered in to the beaker or dish, this process is repeated by adding chloroform until it again reaches the top of the filter. Two extractions of the same plant material are usually sufficient to remove all of its THC oil. The plant material is discarded; the same procedure is repeated until the beaker or dish becomes full of solvent. Now the beaker or dish is placed on an electric stove or hot plate and heated slowly to a very low boil. When the chloroform is being evaporated, the area must be completely ventilated! In the early days of medicine, chloroform was used as an anaesthetic until harmful side effects [such as liver damage! -ed.] were discovered, so it is clear that extreme care must be used when evaporating this solvent. After the solvent has been evaporated, the same procedure is repeated until all of the plant material has been treated. The oil is collected and stored in a glass pipette. These can be obtained at a scientific supply and are inexpensive. The oil is drawn into the tube (this may be easier if the oil is first heated a bit), and the tube capped at both ends. Resin is best stored inside airtight containers and in an area of low light and humidity. |

![]() | SUPERCRITICAL FLUID EXTRACTION The ultimate way of making high quality hash oil with butane. Solvents can also be used to extract raw cannabis oil from harvested cannabis flowers. Raw cannabis oil contains: • Psychoactive cannabinoids in high percentages • Plant tissue in low percentages • Chlorophyll in low percentages • Trace elements in low percentages (non-psychoactive water soluble matter) Raw cannabis oil is best extracted from highly resinous strains like the Afghani cannabis plant. Strains that have a semi-dry or dry floral trait should not be considered candidates for cannabis oil extraction because the amount of oil extracted does not necessarily justify the procedure, although the end material is a very high-grade form of hash oil. With these dry strains you may have to perform the extraction process several times before a substantial amount of psychoactive oil is produced. Like any other cannabinoid extraction process, you are better off using a resinous strain to rationalize the end results. Isopropyl, ethanol and acetone used to be popular solvents for hash oil extraction but the process for each one is time consuming, costly and material-intensive. They often result in smaller amounts of lower grade than you hoped for. There is a much easier and more affordable way to enjoy a purer form of cannabis oil. The process known as butane extraction produces better results in a much shorter time frame. Butane extraction is the most popular form of raw hash oil extraction because it is based on an industrial process known as SFE (supercritical fluid extraction) and is very easy to perform. You should only use butane fuels that are recommended for flameless lighters (jet torch will also do). These types of butane are much cleaner and extract raw hash oil better than other butane fuel types that you commonly find at the drugstore or fuel depot. A good tobacconist shop should stock flameless lighter butane. Butane is a very good solvent for hash oil extraction because it separates cannabis oils from most other useless plant/bud matter. This type of filtered oil is sometimes nicknamed ^Hash Honey Oil' because the results are like an amber honey. SFE can produce very fine and pure cannabis oil from resinous strains. It simply separates cannabis oils from plant tissue, chlorophyll and the other trace elements that we find in most raw hash oils. You can imagine the final weight of the butane extracted oil to be the equivalent of the total weight of anything sticky or oily on the plant separated from the rest of it. Once you have obtained the butane, you need a pipe that measures 1.5 to 2.0 inches in diameter, is 16 to 24 inch long and is made from either polypropylene (PP) or polyethylene (PE). Basically, the bigger the pipe, the more bud it can hold. Do not use PVC piping because it can be a health hazard. Either PP or PE piping works best and can be found in any good DIY store. Each end of the pipe will need a cap. You should be able to get some PP or PE caps at a home improvement store or someone can make them for you. If you cannot find any suitable caps, you can try using large bottle caps and 'blue tack’ to hold them in place. You need a stand to hold this pipe. A lab stand is perfect for the job but anything that will hold the pipe up off the ground is fine. You also need a filter. An extremely fine cloth filter, like a bandage wrap with pores or fine pipe gauze, will work well. Any filter that will allow oil to drop through but leave the plant matter in the pipe is ideal. Coffee filters will not work very well unless they have a large pore size. You also need a clear plastic measuring cup, a clean wooden stick (like a medical tongue depressor) and some nicely manicured bud. You should be able to use 1 oz or more of bud in the above pipe design. In the diagram below you can see the parts in alignment without the stand. The parts are as follows: 1) Butane canister, 2) Top cap with hole for canister, 3) Tube for holding the bud, 4) Filter, 5) Bottom cap with perforations, 6) Cup to catch the oil and butane. The whole unit should snap into place as follows. NOTE: Butane is a fuel and will combust when ignited by anything like a spark. If you do not have a professional SFE unit with the proper ventilation, then use butane SFE extraction carefully, outdoors, away from any buildings and other people. Avoid inhaling butane or the exhaust from butane extraction by wearing a facemask. PROCEDURE: 1. Drill a hole in the end of the first cap that allows the nozzle of the butane canister to fit neatly into it. 2. Drill six small holes near the center of the second cap. 3. Place the filter in this second cap. 4. Attach the second cap to the pipe. HOW TO MAKE HASH 5. Fill up the pipe extremely loosely (never cram it in) with finely ground bud. 6. Attach the first, or top, cap to the pipe. 7. Mount your pipe on your stand and place it over your clean measuring cup. 8. Open the butane can and turn it upside down placing the nozzle in the top cap. Fill the pipe up slowly, allowing the butane to draw the oils down through the tube. Butane Filter 9. Remove the butane canister when its weight stops decreasing (meaning it is empty) and move a safe distance away. 10. Wait fifteen to twenty minutes before approaching the apparatus even if the top cap has given up any viable signs of fume release. The butane should have evaporated away, leaving an oil/butane mixture in the cup. 11. Open the top cap to allow all fumes to escape. Butane will still be active in the cup and bud in the pipe so leave these two alone for another twenty minutes. The remaining oil in the cup is raw hash oil with some butane. 12. Any remaining butane can be evaporated by placing the cup into a dish of hot water. 13. You now have made raw hash oil. It should be ready to smoke in a few hours. Tips for butane extraction I have heard of numerous SFE accidents caused with butane. All of them happened the same way. Most SFE butane extraction accidents occur when the pipe is full of bud and butane is dripping down into the cup below. Any flame, spark or ignition will cause that butane to become unstable. Almost all of the accidents I have heard about occurred because a flame or spark ignited the butane. In most cases it was a smoker who caused this. Do not smoke when you are performing SFE with butane, period. If you can do that then butane extraction is actually one of safest methods of hash oil extraction available to the home grower. During the SFE process the butane must be left alone to drain down into the plastic cup along with the raw hash oils that it collects on the way down. Vapor and fumes will come out through the top of the cap and the cup. After about fifteen minutes, most of the butane will have passed through. There may be some remaining butane/oil extract near the filter and end cap but forcing this through (by blowing, tapping or pushing) into the tube may add unwanted matter to your extract. A brief shake is all that is needed to help the remainder into the cup. Use the wooden stick to wipe away any oil/butane mixture from the base of the filter. This butane/oil extract in the pipe and cup is still part of the SFE process and the butane will continue to evaporate. Butane has a low boiling point (even evaporates at room temperature) and if you need to boil off any excess butane in the cup simply place the cup into a bowl of hot water (not boiling!) and watch the butane evaporate. This is why butane extraction is best done outdoors. Butane will eventually evaporate into the atmosphere instead of into your home where it can become a fire hazard. You should eventually be left with an amber-colored substance in the cup. This is your high-grade hash oil! The butane should be completely evaporated by heating the cup of raw hash oil/butane in hot water. Your high-grade hash oil is sticky to touch and best smoked in small quantities because of its quality. Oil is best enjoyed by placing a small glob of oil on some foil and heating the foil lightly from beneath, causing the oil to boil and vaporize. This vapor should be then consumed using a Pyrex straw (plastic straws burn and inhaling burning plastic is not good). As a note: Cannabis oil is an excellent format for medicinal use because it is very pure. By vaporizing cannabis oil, the user can enjoy a pure form of cannabis without carbon monoxide. Here are some other tips for butane extraction: • After you remove the hash oil from the cup you can use some isopropyl (90 percent minimum content) to collect any residual oil that may by still in the cup. Add a small amount of isopropyl to your cup and swirl it around. Heat the cup at a very low heat (less than 200 degrees to avoid THC evaporation) to evaporate the isopropyl, leaving the remaining hash oil collected from the rim of the cup. • You can perform a second extraction using the same procedure with the used bud to remove any excess oil that is still left in the bud. The bud should be mostly devoid of any cannabinoid compounds and should be disposed of. • A slow release of butane into the pipe allows sufficient time for the SFE to take place, improving the quality of the process and the final amount. Try not to force all your butane in too quickly. • The butane you use must be as pure as possible. Bottled butane is usually mixed with chemicals so that when it leaks you smell it. These chemicals can interfere with the butane/cannabis SFE process. • Use a bud grinder to make sure that your bud is powered down as much as possible. The finer the mix the better the extraction results. • You should be able to get between 5 and 10 grams of hash oil for every 1 oz of good quality resinous bud that you use. • You can also process leaf or trim using butane SFE. You can expect about 0.5 to 2 grams of hash oil for every 1 oz of trim used. This depends on the quality of the trim. |
