Shatter

Shatter is a cannabis extract that is solid and translucent as glass to the eye. It achieves its glassy appearance through specific processing techniques involving solvents such as butane. Many of the essential compounds, such as THC and CBD, are in shatter in a highly concentrated, compact form.
This glassy extract has a reputation for being a potent extract, although its potency can vary depending on the chemical composition of the source plant and the extraction techniques and equipment used.
