How To Decarb Shatter: 4 Easy At Home Methods

Share

Shatter is an efficient method of storing concentrated cannabinoids. It is made by dissolving marijuana into a solvent, such as butane. This makes a more potent concentrate than hashish or buds. The resulting yellow substance is called honey oil.

To use shatter for vaping and edibles, you have to decarboxylate it, often referred to as decarbing. Here we will cover four methods to decarb shatter at home. We recommend that you wear protective gloves. We assume you have the shatter in a glass vial. Here’s the video of the processes, followed by a breakdown of instructions for each method. Proceed at your own risk.

This guide is based on a video at HowToWeed. Below is the video guide and keep reading on for the written instructions.

Method 1: Stovetop, decarb shatter in pan

Get a medium-sized saucepan or other cooking pot and out it on the stove. Add some cooking poil to about a half inch of depth. Heat it to 250° F. Place the vial of shatter in the pot. The shatter will melt and bubble. Wait for the bubbles to stop forming. You should have a clear golden liquid when done.

The jar of shatter goes in the hot water to decarb.

Method 2: Using your toaster oven to decarb

Place your shatter container in the toaster oven on a stable surface. Set the oven to bake at 250° F. It will melt and begin to make fizzy bubbles. Wait for the bubbles to stop forming. This means it’s done. This method takes about 50 minutes. However, don’t fret over our exact times, as yours may vary.

Method 3: Crock Pot, slow cooker shatter decarb

Take a counter-top crock pot and add cooking oil to it, to about a half-inch depth. Heat the crockpot to 250° F. Place the shatter vial in the middle of the pot and wait. The shatter will melt and bubble. Once again, we wait for the bubbling to stop to know the shatter’s done. This method takes 80 minutes by our estimate.

Method 4: Hot Plate, simple but most don’t have these at home

Heat the hotplate to 250° F. Place the vial of shatter on the hotplate directly. Place a larger beaker over the vial. The shatter will begin to melt and bubble. Stop the process momentarily and scrape the inside of the vial, making sure to push all solid matter together down into the bottom section of the vial. Restart the process and wait for bubbles to stop forming. Continue heating until pure liquid.

Get every last bit for maximum efficiency.

Why would you want to decarb shatter?

The point of decarbing shatter is that shatter is largely composed of THC-A. This is the acid form of THC, which is not psychoactive. Decarbing it returns it to its regular THC state.

  • my shatter barely bubbles .is it cus heatwas used making it and could i be decaarbing it too long losing potency ?Did some whote runts at 250 degrees 35 mins about and its not as strong as bluberry i did in a shot glass my first time I have these exact containers now but seems like its working less in my toaster oven.any ideas?

  • There are so many incorrect statements in this article that I would advise those who browse to go somewhere else before decarbing. What is said here will work - sort of - but many of the supporting statements are wrong and indicate an overall ignorance of the science behind what is being described. It would be pointless to go through each of them here. But I will correct one of the responses to a comment. To the person asking about the olive oil decarb: do not throw it away. I can't believe the jackass who thought it might be the best 'solution'. Olive oil is used extensively in cooking. I has a smoke point of around 375F. Use it to bake whatever you want below that temperature. In fact, you may not even find it necessary to decarb if you intend to bake. You decarb for things like gummies since no heat is involved in the recipe.

    And BTW, the 'natural state' of THC is not the decarbed state. You get a buzz when you smoke it only because the heat from burning it does an on-the-fly decarb.

  • I mixed my shatter with olive oil before I decarbed it and I don’t think it worked. I mixed it into marshmallow fluff and made rice krispy treats. Can I rebake them and still turn THC-a into THC or us it too late?

  • Thank you very much for all the wonderful information this will be my first time trying this and I hope it turns out for I consume a lot of edibles my lungs are too old smoke too many cigarettes

  • I have a machine for decarbing flower, do you think it will work for concentrate as well?

  • Does it usually take a long time? I see most people say 25-50 minutes but its been like 2 1/2 hours in my toaster oven at 250°

  • Just wondering, does the size of jar matter? I have a glass cup size mason jar that I use to melt and infuse coconut oil with reclaim, could I use this same jar to decarb the wax?

    • Saw a video on YouTube of a guy doing exactly that as Silicone can withstand the heat necessary to decarbonated your concentrate and then some.
