Wax is made by blasting plant material with a solvent using a closed-loop extraction system. The resulting slurry is heated at low temperatures and whipped vigorously to remove all residual solvent. Because the product is whipped by hand, it gains airy peaks that are similar to whipped topping. Wax is generally drier and more crumbly than its counterpart budder. Cannabis wax refers to the softer, opaque oils that have lost their transparency after extraction. Unlike those of transparent oils, the molecules of cannabis wax crystallize as a result of agitation. Light can’t travel through irregular molecular densities, and that refraction leaves us with a solid, non-transparent oil.
