Shatter, with its flawless amber glass transparency, has a reputation for being the purest and cleanest type of extract. But translucence isn’t necessarily the tell-tale sign of quality – the consistency and texture of oil comes down to different factors entirely.
The reason shatter comes out perfectly clear has to do with the molecules which, if left undisturbed, form a glass-like appearance. Heat, moisture, and high terpene contents can also affect the texture, turning oils into a runnier substance that resembles sap (hence the commonly used nickname “sap”). Oils with a consistency that falls somewhere between glassy shatter and viscous sap is often referred to as “pull-and-snap.”
