How to Make Shatter2018-11-29T01:29:22+00:00

If you love weed and haven’t had your head in the sand for the last few years, surely you’ve heard of shatter. Maybe you’ve even toked the stuff. If you have, you know it’s awesome.

But how do you make shatter? Here, in brief form, is a guide for how to make the perfect batch of shatter. For simplicity’s sake, we’ll stick to the popular “BHO” (butane hash oil) method.

How to make shatter

How to Make Shatter

We are going to walk you through everything you need to know about how to make BHO. To start, keep in mind that the BHO method tends to be a hazardous process. Making shatter indoors is a terrible idea and stands a decent chance of blowing your house off its foundation. But BHO can be done in relative safety if thorough caution is used.

The first step to making shatter is to gather your supplies. You’ll need:

  1. an ounce of uncut marijuana
  2. an “extraction tube”
  3. at least one butane canister
  4. a coffee filter
  5. an electric range and double boiler
  6. a Pyrex dish to collect the shatter
  7. strips of parchment paper
  8. single-edged razor blades

Next, grind your weed and let it sit for a while. You want it to be dry, not too fresh. If you pack an ounce into the extractor and spray it with a full 12-ounce canister of butane, you should get roughly 3.5 grams of shatter. This amount of concentrate you produce will depend on how laden with crystals the buds are; some BHO extractors get up to 20% yield.

Step 1.  Fill the extractor with ground marijuana

To continue making shatter, fill the extractor with pot. These “honey oil” extractors can be purchased at most head shops, but you can also make one yourself. Be sure the weed is packed tight, but not too tight. You don’t want air pockets, but you want the butane to saturate all the marijuana.

Step 2.  Saturate marijuana with butane

One end of the extractor should have a small hole, the other a cap with several holes and an internal filter. Store-bought extractors come with a filter, but coffee filters also work for DIY. To make your concentrated marijuana, carefully and slowly spray the butane through the top hole until the canister is empty. A thick green-gray-brown oil should drip from the bottom holes into your Pyrex container.

If you want to know how to make marijuana wax without destroying your home at the same time, listen up. This part is absolutely essential: Spray the butane outdoors, with ample ventilation, as far as possible from any buildings, vehicles, or other potential sources of ignition. Even a hidden pilot light could spark an explosion, and you definitely don’t want that.

Step 3.  Evaporate off the butane

The next step in making shatter can also be rather dangerous. Fill your double boiler and put it on a hot electric range. Make sure it’s electric: Use a gas stove and you’re liable to start a fire. Now place the Pyrex container in the top portion of the boiler and let the liquid evaporate. This gradually removes the butane, leaving you with true shatter.

Butane Hash Oil Evaporating BHO

It’s important to make sure you boil all the solvent away when you make shatter – otherwise you could end up smoking a product still tainted by butane, and that’s bad for your lungs, not to mention potentially explosive. You’ll know the process is finished when the shatter stops bubbling.

Step 4.  Purge remaining butane

At this point, you’re left with a thick, amber shatter with trace amounts of butane, and many feel that the solvent must be further purged before consumption. This can be done using a pressurized vac pump, and our grower’s process goes like this.

“We vacuum purge all concentrates to remove the remaining traces of liquid butane.  We do this using a 3 cfm one-stage vac pump (don’t waste your time with two-stage units). The BHO is placed in a thin layer on a glass dish inside the chamber, and the air and butane are sucked out through the pump. It is important to have a gauge that shows you the temperature inside the chamber to avoid burning off the oil.”

After the vacuum purge operation, you will have removed almost all traces of butane from your cannabis oil, leaving you with a pure, flavorsome product.

Step 5.  Scrape and store

Finally, use a razor blade to scrape the potent concentrates off the bottom of the container and place it on parchment paper to cool. You may need more than one razor to scrape up your full-extract cannabis oil, as they can become hopelessly sticky.

And that, in a word, is how to make THC wax. The only thing left to do now is smoke it!

    Do you need to decarb the herb before starting this process?

      Hi Steve- No, there is no need to decarboxylate your buds before making shatter.

    Doesn’t it have to go through a vacuum chamber or oven?

    • Christian February 22, 2017 at 9:42 am - Reply

      Yes, it should for a properly clean product.

    The double boiler confuses me a bit. Most double boilers I’ve seen are smaller, round pots. What type of double boiler would be big enough for an entire pyrex dish to be set in? Can you elaborate on how the pyrex and double boiler interact? Thanks!

      For purging butane from concentrates with a double-boiler, you would need to use a smaller, circular pyrex dish, as opposed to a large, rectangular one.

    Would I be at risk of blowing my house up if my electric stove is near a pilot light when I’m doing the double boiler evaporation or would most of the fumes be relatively contained?

      DO NOT use butane indoors!!!

    Just boil a kettle before hand… then put a baking tray underneath your dish and keep topping up with hot water as needed and stir out the bubbles with a tooth pick 🙂

      Should I pour any water inside the kettle before boiling it?
