ROSIN Rosin is produced through an extraction process that utilizes a combination of heat and pressure to nearly instantaneously squeeze resinous sap from your initial starting material. It’s a solventless technique, meaning the process does not require use of any foreign substances. Instead, rosin uses a mechanical process involving heat and pressure to extract the resin from the plant. Other extraction methods utilize light hydrocarbons such as butane and/or propane. Often, these complex and mechanical systems require a lengthy purge to safely remove most, if not all of the residual solvents from the final product. Rosin uses heat and pressure and does not require any additional cleaning, so your final product is clean in other words, Rosin is essentially shatter without any solvents.
