How to Decarb with a Mason Jar

Decarbing is an important process when it comes to making edibles in any form - gummies, brownies, cookies, and more. Decarboxylation is an activation process that converts herbal compounds into those needed to deliver the desired effects of your flower. It is a critical step in ensuring your flower delivers the desired potency to your infused creation. 

One of the ways you can decarb your flower for edible production is with a mason jar. By including the process of dexarboxylation, you can ensure the next edible you ingest delivers the full benefits the herbal compounds offer.

Pros and Cons of Decarbing with a Mason Jar

One of the benefits of using a mason jar to complete the decarb process is that they are easily accessible. With that in mind, it is also good to note that this process can be timely and require careful attention. Follow the steps below or if you’re interested in learning an even simpler way to decarboxylate your flower – check out our blog on the easiest way to decarb using a home decarboxylation and infusion machine like LĒVO.

Decarbing with a Mason Jar in the Oven

One of the most common ways to decarb with a mason jar is in the oven because it allows you to reach desired temperatures fast. If you’re going with this method make sure you have enough heat-protective gear. You will also need the following baking tools: gloves, a baking tray, and a kitchen towel.

First, break apart the hemp or flower in the mason jar, making it as small as rice grains. Then, preheat the oven to around 220 to 240 degrees Fahrenheit. From there, wet your kitchen towel and fold it twice before placing it on the baking sheet. Place the jar on top before putting the whole tray inside of the oven on the middle rack.

The towel will keep the jar in place and prevent it from touching the tray. Direct contact is often too much heat on the glass and may cause the mason jar to break.

Every 15 minutes of baking, remove the mason jar and handle it with your oven gloves. Shake it gently to disperse the hemp and place it back in the oven. Bake it for 60 minutes before removing it then let it cool for another 30 minutes. After cooling, you have decarbed material you can use for cooking.

How to Decarb Using a Mason Jar and Pressure Cooker

If you have a multicooker, it can serve as a helpful tool for the decarb process. One of its advantages is that you can complete the process in half the time than with an oven. Like the previous method, you’ll have to break apart the material and place it inside the mason jar. You’ll also need a small metal or wire rack to place the mason jar on so it doesn’t directly touch the cooker.

You’ll need to fill up the pressure cooker until there is enough water to cover most of the jar. Don’t place too much, as it will lead the mason jar to float and interfere with the decarb process. Placing water halfway through the cooker before placing the mason jar inside is a good starting point. Then, set it to pressure cook for 40 minutes on high.

The water will boil, and the decarb process will begin. After 40 minutes, release the pressure manually, but be careful and wear heat-protective gear for the hot steam. Once you remove the jar from the cooker, allow it to cool for 30 minutes.

How to Decarb Using a Mason Jar and Pot of Water

The process of decarbing using water is similar to that of a pressure cooker but it takes twice the time. It’s an alternative for those who may not have an oven or a multicooker in their home. You’ll need heat-protection from the hot pot, as well as a small rack that can fit inside. Alternatively, a wet towel inside the pot can also work.

Fill the pot with water halfway through and place the jar inside. Like the multicooker, you don’t want to put too much water in it. Don’t heat the water before placing the jar inside as it could disturb the decarb process.

Once the water starts boiling, lower the temperature until it’s simmering. You want to maintain the boiling temperature and avoid it from burning. Then, leave the jar for sixty-ninety minutes. From there, remove it and let it cool for another half hour.

A Better, Safer Decarb Method

While the mason jar is a simple tool that allows you to decarb, it can get messy and there’s always a risk that the process doesn’t go as expected. You also face the risks of injury when dealing with high temperatures and glass. The good news is that LĒVO machines are available to help you decarb safely and conveniently.

Can candle melters do the job at just under 135F in 48-72 hours? I imagine a mason jar with the ceramic plate between the jar and the hot plate would prevent shattering at this low temperature? Wondering also if I should cover this all in a towel to prevent shattering (saw this online) or if that would be a fire hazard?
LEVO Oil Infusion, Inc. replied:
Using a candle melter at just under 135°F for 48-72 hours might not be effective. The process typically requires higher temperatures to activate flower.

For example, using an oven, you would preheat to around 220-240°F and bake for about 60 minutes. If you prefer a safer and more controlled method, you might want to consider using a LEVO machine, which can activate and infuse with just the push of a button.

As for using a towel, it’s generally used to prevent the jar from moving and to distribute heat evenly, but you should always be cautious of fire hazards.
