In other words, it’s completely free of solvents and chemicals; it’s totally pure and is considered a cleaner cannabis extract. Obtaining rosin involves using heat and pressure to extract cannabis compounds, and in order to do that, you need a rosin press. Put simply, a rosin press is a device that features two heated plates or pads. Cannabis material (flower, kief, sift, bubble hash, etc.) is placed in the press and it’s compressed, and that compression squeezes hot oil out of the organic materials. As mentioned, no solvents or chemicals are used, but rather just heat and pressure, which leaves you with a pure extract in the form of rosin. This process was first used to make rosin for violin bows (the material that is rubbed across the fine hairs on a bow, allowing it to create more friction and better sound); hence why this form of cannabis concentrate is referred to as “rosin”. Because it’s as pure as it gets, rosin is healthier than other types of cannabis extracts, and the effects are far superior. While you could totally purchase rosin at your local dispensary or maybe even a head shop, it can cost a pretty penny. If you want to save yourself some money – or you’re thinking about selling it yourself – you might be considering making your own rosin.
