Marijuana Extracts: Hash Oil

Make Hash Oil With Marijuana And Butane

This is one method of making hash oil from marijuana with butane as the solvent, based on work by Indra. The result is a beautiful and extremely potent grade of hash oil that is referred to as honey oil, because of its color and consistency.

Some people say to avoid butane based hash oil methods because the butane itself may add impurities to the oil that can be unhealthy. An alternate method to make hash oil with alcohol as the solvent is preferred by most people for medical grade oil.

The butane extraction method utilizes totally over-the-counter butane gas as the extraction solvent, and requires nothing that is difficult to purchase. Yield is slightly lower compared to alcohol extraction, but potency is slightly higher.

28 grams of good marijuana bud will produce about 4-5 grams of honey oil, with this method and butane as the solvent. You may get a bit more with exceptionally potent marijuana, or less with lower quality material.

Butane and carbon dioxide selectively solvate the desirable cannabis oils, pulling out only an amber colored honey oil and leaving the undesirable vegetative oils, waxes, chlorophyll, etcetera, behind in the plant matter.

WORK OUTDOORS away from living entities or anything that might catch on fire if the butane contacts any kind of spark. Work away from anything that might produce a spark. Ensure you are the only victim, if things go wrong.

List Of Materials

Set Up

A list of what is needed, the dimensions of the items, and an explanation of how they are employed to produce hash oil is located in the materials section of this guide.

Set up your work area and have all of your materials together. Choose a well lit area and a solid work surface that can easily be cleaned up. Make sure there is nothing near you that can ignite the butane fumes. Butane Honey Oil Extractor Tube Made Out Of Plastic

For these instructions a tube made out of plastic, that won't release dangerous chemicals when it comes into contact with butane, was purchased. Some people use a glass or metal tube.

Hole In Top Of Butane Honey Oil Extractor Tube To Accommodate The Nozzle From A Butane Can The tube is large enough to hold about half an ounce (14 grams) of ground marijuana buds that will be converted to hash oil.

One end of the tube has a single hole that will accommodate the nozzle from a butane can.

The hole is correctly sized to snugly receive the little outlet nozzle of a butane can. This end of the tube will be held in the top position, and the butane in the butane can will be emptied into this end.

Holes In Top Of Butane Honey Oil Extractor Tube To Allow The Butane And Oil To Flow Out The butane will flow down the tube and extract the oil from the marijuana.

In order to flow out of the tube, the bottom end is capped and has 5 small holes in it to allow the butane and oil to flow out into a pyrex dish, or similar container.

A piece of coffee filter is placed in this, the bottom end, between the marijuana and end cap, to stop small pieces of marijuana from flowing out with the honey oil and butane.


To start, pulverized the marijuana into coarse material with an herb grinder, coffee grinder, or by some other method. Ground Up Marijuana Buds And Table SaltYou want it about the same size as you would roll into a joint, not as fine as powder.

See the comparison image of the relative size of the ground up marijuana, it's several times larger than grains of table salt.

Set a coffee grinder to the coarse setting, if available, and don't grind too much. It took less than 5 seconds to grind these buds to this. You don't want to end up with marijuana powder, because that is too fine.

Fill The Butane Extractor Tube With Ground MarijuanaAfter grinding the marijuana, fill the tube up with it. You want it filled and loose, not packed down tight.

Then put a piece of coffee filter (or paper towel) inside the bottom end cap for filtration. This is to keep plant material from exiting the holes with the butane and oil.

Put the bottom end cap, with several small holes in it, on the end of the tube. This is the bottom end. Find a location outdoors with a decent breeze. You want these butane fumes to be quickly carried away.

Hold the tube (single hole facing up) over the pyrex baking dish. Position the bottom end of the tube about 2 inches (5 cm) over the pyrex dish to eliminate splatter loss.

Turn The Butane Gas Can Upside Down And Dispense Into Tube Turn the butane gas can upside down and dispense the gas into the tube via the single top hole.

Be brave, swift, careful. A spark at this moment would spell disaster, since you have basically created an incendiary explosive device that is leaking.

The butane moves down the tube, extracting the cannabis oil as it goes. When it gets to the bottom, it begins to drain into the receiving vessel. Notice the pale yellow-green-gold hue of the extract.

After a few minutes, the butane extract will finish draining from the tube to the receiving vessel. Maintain caution with the tube, however, since there is a lot of residual butane still evaporating from within the tube, notice the stream of fumes coming from the top hole.

When it slows down to a drop every few seconds, you can tap on the top hole with your finger and it will help push the last of the liquid butane out, or one can gently blow into the top hole to do the same thing.

Butane In Pyrex Dish Starting To Evaporate The butane in the pyrex dish will start to evaporate. Having a very low boiling point and being volatile, the collected butane will likely begin boiling at ambient temperature.

The pyrex will gradually frost up as the butane cools it down, slowing down its rate of evaporation. You can speed this up by holding it in your hands. A better way is to set it in a saucepan containing a little bit of warm water.

If you do, watch the butane start bubbling madly with the increase in temperature and marvel at its low boiling point. Again, do this outdoors with a nice breeze! No smoking!

You may have to repeat the process several times if you have a lot of marijuana to process but the result is worth the effort. When more than a few ounces of marijuana is being converted to oil, it is best to have 2 or more pyrex dishes and alternate the dish you extract into.

Honey Oil In Pyrex Dish After Butane Has Evaporated When you are finished, you can simply let the butane evaporate. It takes a minimum of 20 minutes for the butane to evaporate.

Use a pyrex vessel with a flat bottom if you choose to scrape the oil from the pyrex, it's easier.

Honey Oil Scraped Off Pyrex Dish And Collected With A Chisel The honey oil will be fairly cohesive and can be scraped off and collected to be stored or used, after the butane has fully evaporated.

An alternate method of collecting the oil is to let all of the butane evaporate off and then redissolve the oil in some isopropyl alcohol (90% or higher).

And then pour the mixture into a vial (or some other type of container) and let it sit uncovered, to allow the alcohol to evaporate. Depending on the amount, it can take several days or longer for the isopropyl alcohol to fully evaporate.

Isopropyl alcohol is not as flammable as butane but fumes can ignite when exposed to a spark or flame, so be sure store it in an area that has some ventilation while the isopropyl alcohol evaporates. After evaporation, put the screw cap on the vial and store it in a cool dark area.

Honey Oil Spread On Rolling Paper

The final product is a deep yellow-amber oil of the highest quality, incredibly pure and potent. This method extracts only the oil. The color of the oil isn't quite as clear as traditional honey oil, but it is just as potent.

Because it is so fresh, it may be even more potent than any oil you may have tried before. Hash oil can start to degrade in less than a year even when stored in favorable conditions (air tight container, darkness, cool temperatures).

Hash Oil Collected To Be Stored In Non-Stick Container Note that this oil has a somewhat higher melt/vaporization point than traditional hash oils. The traditional dispensing method (dipping a needle or paper clip in, getting some oil on the end, and warming it with a flame to get it to drip off) still works with this stuff.

However, it seems you have to be more careful with it because it doesn't heat to liquid state as quickly or in the same manner. It can easily be burned up on your needle if you are used to hash oil that is produced using other solvents. So be careful.

I also observed that unlike honey oil derived from traditional methods, this hash oil is not immediately soluble in room temperature alcohol. It first needed to be warmed up, before it dissolved fully.

optional 90% plus isopropyl alcohol

*** butane *** A can of butane will usually be sold by volume. The volume you will need is about 10 fluid ounces (300 milliliters) of butane for each ounce of marijuana you intend to process.

You can locate a supplier for quality butane at good prices by searching through these listings. Butane that is refined several times (like 5x refined butane) is best, but any brand of butane for refilling lighters will work.

Butane for refilling lighters is a good idea. Butane for camping stoves may contain additives and should be avoided. Stay away from anything unless you are absolutely positive that it is pure butane.

*** marijuana *** For myself, bud from good marijuana with an estimated dry weight content of 10%-14% THC (not super premium but a step up from regular commercial), the return is about 4-5 grams of honey oil per ounce of marijuana.

Shake and bud trim will produce clean and potent gold oil with this method, so if you grow save the bud trim. You can also extract potent hash oil from bad tasting marijuana too. But bear in mind, a better grade of marijuana will produce a larger yield of hash oil.

*** coffee filter *** A small piece of coffee filter can be cut from a larger piece and placed in the bottom end of the tube, between the marijuana and the end cap, to prevent small pieces of marijuana from flowing out into the oil with the butane.

*** storage container *** Hash oil can be stored in vials, dark color vials are better because they will block some light (which will degrade THC over time). A non-stick container is also a very good choice for hash oil storage.

Glass vials with screw caps are a good means of storing hash oil. The size of the vial you get will depend on the amount of oil you plan on producing.

After the oil in the pyrex dishes has been mixed with isopropyl alcohol, if you choose this option, it can be poured into the vials (a small metal funnel makes this more practical) and the alcohol will evaporate, if the top is left off.

*** pyrex baking dish *** Butane is very cold, a pyrex baking dish is recommended for this procedure because it is made to withstand extreme temperatures that would break most other types of materials.

For personal needs, several years ago a set of two pyrex baking dishes exclusively for making hash oil was purchased. This is because 5-10 ounces of marijuana were processed into honey oil at a time.

One of the pyrex dishes in the set measures 11 by 7 by 1.5 inches (28 by 18 by 4 cm). The other is 13 by 9 by 2 inches (33 by 23 by 5 cm). It is best to stick with a container somewhere near these sizes or a bit larger, rather than much smaller.

This is to ensure that no hash oil is lost because the container was too small and some splashed up and over the side. When processing 1-4 ounces of marijuana a single pyrex dish, of the size mentioned above, should be adequate. But for more than 1 batch you can alternate between 2 dishes.

*** tube and end caps *** The tube extractor in the images above on this page is a product called the honeybee extractor that can be employed for the purpose of making hash oil from marijuana.

It is made of plastic that does not release chemicals when exposed to butane. It is 6 inches (15.24 cm) long and has an inside diameter of 1 and 3/8 inches (3.50 cm). Capacity is about 14 grams of ground up marijuana buds.

One end of the tube has a single 5/32 inch (3.97 mm) hole that the tip from a butane can will fit in. The bottom end is capped with 5 separate smaller holes that are 1/16 inch (1.59 mm) diameter in it, to allow the butane and oil to flow out.

Having personally used the honeybee extractor to produce many batches of honey oil since 2006, it works really well with no problems and will last at least a decade. The queen honeybee extractor also looks like a similar product.

You can make a tube to extract the oil with any suitable material you have available. Common plumbing tube made out of PVC or other types of plastic might release harmful chemicals when exposed to butane.

Some people prefer a glass or metal butane hash oil extractor. If you utilize any type of metal pipe be careful, the pipe itself can easily create a spark that would be disastrous.

The actual length and diameter of the tube is up to you. A tube 6 inches (15.24 cm) long that has an inside diameter of 1 and 3/8 inches (3.50 cm) is enough to process about a half ounce (14 grams) of ground marijuana buds.

If you plan on extracting from smaller amounts of marijuana than an ounce, the tube can be narrower and/or shorter. If you plan on extracting from larger amounts of marijuana than an ounce, the tube can be wider and/or longer.

Less dense material than marijuana buds, like shake or bud trim, will occupy a greater area. So if you plan on making oil from material other than buds, the tube will have to be wider and/or longer to accommodate an ounce of material.

*** well lit work area *** A well lit outdoor work area with a good breeze, away from any potential source of sparks, is required.

*** some kind of blade *** You can utilize a glass scraper, chisel, or some kind of blade like a razor blade, to scrape the oil from the pyrex dish.

*** optional isopropyl alcohol *** Instead of using a glass scraper or blade to scrape the oil from the pyrex dish, 90% or higher isopropyl alcohol can be utilized to dissolve the hash oil in the pyrex dish after the butane has evaporated.

Once all the honey oil is dissolved, it can be poured into a storage container for long term storage. Before using the oil, leave the cap off the container until the isopropyl alcohol evaporates. It can take a few days or longer depending on the amount of isopropyl.


1 --- Remember butane is extremely flamable and can cause an explosion in a confined area. You must work outdoors at a safe distance from anything that might produce a spark.

2 --- With hash oil that will be prepared into food or drink, marijuana should be decarboxylated prior to making hash oil. Remember, when oil will be made into food or drink, decarboxylate first.

3 --- The oil will remain in semi-liquid form for a few hours after the butane evaporates from the pyrex dish. If left uncovered for about 24 hours, all the remaining butane will evaporate, and the honey oil will be more of a solid.

4 --- If you work with isopropyl alcohol (optional with butane), be very careful and watch what it comes into contact with. Alcohol can extract harmful chemicals from some types of plastic, and similar materials like rubber.

Some people recommend not letting metals like aluminum, copper, iron come into contact with solvent because they can leach metals into the hash oil. However, stainless steel is safe.

When working with alcohol, make sure that it only comes into contact with ceramic, glass, porcelain, silicone, stainless steel, paper, etcetera. Containers with teflon, like t-fal, should be avoided.
