What Is Rosin and How Can I Make It at Home?

ROSIN USES A solvent-less extraction technique that allows anybody to make their own high-quality hash oil from the comfort of their home. Aesthetically, rosin is almost impossible to distinguish from shatter or sap. However, the difference between the two is that rosin is completely free of the residual solvents often left behind by hydrocarbon extraction processes (e.g., butane, propane), and therefore free of the risks that go with those other forms of at-home extraction.

Rosin can be made safely and inexpensively in just minutes by using ordinary household tools. This method utilizes heat and pressure to squeeze the cannabinoid-rich resin from your flowers, bubble hash, or kief. Your average hair straightener, some parchment paper, and a collection tool are all that’s needed to produce a hash oil that rivals hydrocarbon extraction methods in flavor, potency, and effect.

Rosin is certainly making an impact in the legal cannabis market. Dispensaries all over the country are beginning to stock their shelves with this easily crafted, incredibly potent, and flavorful product. Let’s find out how it can be made.

Ingredients Needed to Make Rosin at Home

1. Hair straightener (try to find one with a temperature setting of around 300˚F or lower—any higher and you begin to lose valuable terpenes as they evaporate)

2. Cannabis (this can be flower, bubble hash, or kief)

3. Parchment paper (unbleached, if possible)

4. Collection tool (many dabber tools work well here, although you can get creative!)

5. Heat-resistant gloves for safety

Note: Like other methods, this is done at your own risk. Please exercise caution when handling the hair straightener and use heat-resistant gloves as an added safety measure—we don’t want you to burn yourself!

Four Simple Steps to Make Rosin

Step 1:

Turn on your hair straightener to the lowest setting (280°F to 330°F) and cut yourself a small 4 × 4-inch piece of parchment paper. Now fold it in half and place your cannabis material in between the folded parchment paper before giving it a light preliminary finger press.

Step 2:

Carefully line the buds inside of the paper together with your hair straightener and apply a very firm pressure for 3 to 7 seconds. You will want to hear a sizzle before you release the pressure—it indicates that the resin has melted from the plant material.

Step 3:

Remove your sample from the hot surface and unfold the parchment paper. Now pluck the flattened nug away and grab your collection tool. This is a very sticky process so be patient and careful. For larger batches, use different clean sheets of parchment and collect your samples together at the end.

Step 4 (Optional):

Remove any visible plant material if you wish. Fold the finished product between the parchment and flatten it to your preference. Then use a clean tool to pick out any plant particulates. You may place the substance on a cold surface for a few seconds if you desire a more stable material to work with.

Now load a nice fat dab of your fresh new rosin and celebrate! You just became an extract artist!
