The simplest way to make BHO shatter with a vacuum, purge is detailed below. If you are not aware of what a vacuum purge is, how it works and most importantly why you need it, this article is here to help you.
For many people, the thought of making shatter at home is intimidating. When you start to throw in heavy words such as vacuum purging it even gets worse. Admittedly, there is a lot of science that goes into making BHO shatter. However, the process is not as complicated as many blogs portray. If you have in place adequate safety measures, the right equipment and the right skill you can easily become the greatest shatter maestro of our times.
Without further ado, let’s get started.
Why Is It Important To Vacuum Purge Your Shatter?
Vacuum purging is done once the trichomes (and THC) have been extracted from the cannabis plant material. Before purging, butane which is used as the extracting solvent (the process is explained later in the article) is evaporated from the shatter. However, some residual butane remains and since it is toxic it has to be completely removed through purging.
Without vacuum purging the shatter will be contaminated and therefore unsafe for human consumption.
What Is Shatter?
How To DIY Shatter Using Butane
This process may take up to 100 hours, depending on the vacuum oven/ apparatus that you are using. With more efficient vacuum purging kits, this may take a few hours.
What you will need
The most expensive equipment that will need to make shatter is the vacuum oven or vacuum purging kit. Other equipment that you will need to buy is the extraction tube and butane canister. These can be easily bought in a marijuana headshop or on Amazon.
- 1 ounce of high-quality cannabis bud (to make 3 ounces of shatter)
- 1 butane canister
- 1 extraction tube
- 1 pyrex dish
- Double boiler
- Parchment paper
- Safety gloves
Safety Measures To Take
Making BHO shatter can easily turn out to be a disaster if safety measures are not in place. Butane is a highly flammable gas and can easily start a fire. There have been a couple of unfortunate incidences with this process especially when it is done inside a house.
The first thing to do is to carry out this process outdoors in a place where there is maximum ventilation. Even when outdoors, make sure that there is no open flame in the vicinity. Lastly have a fire extinguisher in sight just in case an accidental fire erupts.
With this, you should be safe to make shatter simply with a vacuum purge.
1. Shred the marijuana into small piece
Ensure that the marijuana is completely dry to allow butane to act on it effectively
2. Load the extraction tube
Pour the shredded cannabis into your extraction tube and pack it until full. Don’t leave any air spaces
3. Saturate the marijuana with butane
After loading your extraction tube, cover the open end with a coffee filter. Place the pyrex dish on the lower end and start pouring your butane into the extraction tube. Let the brownish-green liquid run until it becomes clear. At this point, the extraction is complete
4. Evaporate the butane
Place the pyrex dish on the double boiler and heat at 90 degrees Fahrenheit. The liquid should bubble until it stops at the point where a waxy substance has formed.
Scrape off the waxy substance onto your parchment paper and allow it to dry.
How To Vacuum Purge Shatter
This is the final step of making shatter. It involves vacuum purging your shatter to get rid of all residual butane.
A simple vacuum oven can do the job pretty well. However, this may take a longer duration.
Place the shatter inside the vacuum oven and set the temperature to 90 degrees Fahrenheit. At this temperature, the butane is past its dissolving point and the cannabinoids are safe. Beyond this temperature and you will start losing cannabinoids.
The pressure should be set at and 27HG – 29HG pressure aiming for a complete vacuum.
Once set, the shatter will begin to bubble as it rises. If it is rising too fast you can reduce the vacuum. Allow it to purge until there are no more bubbles or reaction. By then, all the butane should have been purged.
Remove your shatter from the vacuum oven and allow cooling. You can place it in the fridge for faster cooling. Once the shatter is well-formed (glassy) place it in a cool, dry place away from direct sunlight.
The Best Vacuum Oven For Making Shatter
We would recommend the Orange A Vacuum Oven
This is a basic vacuum oven that is easy to use at home. This oven self regulates its temperature. It is suitable for anyone starting on a budget. It can be bought on Amazon.
Can You Use A Normal Oven To Purge
A normal oven cannot be used to purge shatter. This is because it cannot create the ideal environment where butane will be purged while preventing the burning and loss of terpenes and cannabinoids.
How To Know When BHO Is Done Purging
When purging, you want to make sure that the bubbling has stopped. A sure-fire way to confirm that all the butane has been eliminated is to carry out a residual solvent analysis test.
The process outlined above is the simplest way to make BHO shatter with a vacuum purge. We will be glad to hear if this information was helpful to you.
