Dabs cover a wide range of concentrate products and shatter being one the more popular. To produce a concentrate or Dab one looks to extract the cannabinoids (i.e. THC/CBD) from the cannabis plant. For Shatter the leftover resin from the extraction process is often cooled into a glassy sheet similar to hardened candy and thus if broken apart it fractures or ‘shatters’.
There are several extraction methods for making Shatter concentrates but all require some form of solvents such as butane, carbon dioxide, or propane through which marijuana buds are processed to pull out their cannabinoids. Then an evaporating solvent is used to gather the remaining resins. With Shatter, an additional filtration process is added to remove occurring fats and waxes. This process is what makes shatter so potent.
A common process among most concentrate manufactures to remove these fats and waxes that are natural to cannabis plants, they often end up stripping out the hydrocarbons knows as terpenes, which give the cannabis its unique flavor and scent. To strive for strength, they back fill with sugars and syrups to add back flavour.
