The Physics Behind Rosin: Heat & Pressure

The Physics Behind Rosin

Rosin extraction is the quickest and easiest way to get the very best out of your favorite cannabis strains. Rosin dabs are packed with cannabinoids and terpenoids, guaranteeing a stellar experience no matter how you use them. But if you want to get the best rosin extracts, you need to know about the physics behind rosin. Namely, heat and pressure.

When pressing rosin, you must apply an appropriate amount of heat and pressure to your chosen material. Doing so will release those flavorful terpenes and powerful cannabinoids you’re looking for. The right level of heat and pressure depends on various factors. Plus, a few other factors come into play. Here’s a guide to the physics behind rosin for anyone looking to optimize their extracts.

The Physics Behind Rosin

Rosin is one of the easiest types of cannabis concentrates to produce. Applying the right level of heat and pressure to cannabis flower, dry sift, or hash releases the cannabinoids and terpenes. As a result, you get an oily extract full of flavor and potency that can be altered and used in various ways.

Although it’s easy to extract rosin, getting the best extracts possible requires some knowledge of the physics behind rosin. When it comes to heat, the temperature you use can alter the outcome of your extracts. Higher temperatures can swiftly release high levels of cannabinoids. However, slightly lower temperatures often produce smoother and more consistent extracts.

Pressure is equally as important as heat. You need to press your chosen material tightly to squeeze as much rosin out of it as possible. Even before you press your material, you need to pack it tightly using parchment paper or rosin bags. You also need to choose a rosin press with the right plate size for the material you’re using.

The exact levels of heat and pressure you should use depend on various factors, including the type of material you’re using and what kind of extracts you’re looking for. For instance, you might find cold-pressing favorable to hot-pressing or you might prefer applying more pressure. Fortunately, buying a rosin press makes it easy to experiment with heat and pressure to optimize your extracts.

Using Heat To Optimize Your Rosin Extracts

Heat is one of the most important considerations when optimizing your rosin extracts. Cannabinoids and terpenes are released at high temperatures, so you need to apply enough heat to release them. However, using too much heat can kill the cannabinoids and terpenes, resulting in lackluster extracts.

When extracting rosin from flower material, temperatures of 200°F - 220°F are recommended. Your extracts will be full of potent cannabinoids and flavorful terpenoids when using this level of heat. If you’re extracting rosin from dry sift or hash, you should use slightly lower temperatures of 170°F - 200°F.

Experimenting with temperatures is also a good idea, although you should always stay above 120°F. For instance, you may wish to try cold-pressing rosin. Cold-pressing rosin from flower material involves using temperatures of 180°F - 200°F, resulting in smooth, stable extracts. For hash and dry sift, use lower temperatures of 140°F - 170°F.

To ensure you press your rosin at the right temperature, make sure you use a high-quality rosin press machine. Basic rosin press machines won’t have temperature controls but will deliver enough heat to ensure you get potent rosin extracts. Some more complex rosin press machines allow you to adjust the temperature, making it easy to experiment with different levels of heat.

Using Pressure To Optimize Your Rosin Extracts

Using Pressure To Optimize Your Rosin Extracts

For the best rosin extracts, you need to apply an adequate level of pressure. If you don’t press your material tightly enough, you’ll miss out on valuable rosin. As such, you want to ensure your material is packaged well and press as much of it as possible. This will result in more potent rosin for you to extract and enjoy.

You should start by ensuring you pack your material tightly. You can wrap flower material using parchment paper. Make sure you fold the paper to wrap your material into a tight package. Using rosin bags can also help you optimize your extracts. Rosin bags are especially important when extracting rosin from hash and kief, but they can also be used with flower.

The plate size of your rosin machine also has a significant impact. You want enough surface area to press all of the material that you’re using. Don’t use too much or too little. Make sure you use the right size of rosin bags or parchment paper for your plates. Using a pre-press mold can also help you pack your material tighter and get more out of each press. 

Rosin press pressure is measured in pounds per square inch (psi). For flower material, 600 to 1000 psi is recommended. For hash and dry sift, 300 to 800 psi is recommended. For more information, read our guide on how to optimize rosin press pressure for higher yields.
