When a substance is described as having luster, it means that it has a shiny or reflective quality on its surface. Luster is a characteristic that reveals how light interacts with the surface of a material. There are different types of luster, which can be classified mainly into:
1. **Metallic Luster**: This type reflects light in a way similar to metals, giving a shiny, bright appearance. Examples include gold, silver, and other metal surfaces.
2. **Non-Metallic Luster**: Substances can also have various degrees of non-metallic luster, which may appear glassy (vitreous), pearly, silky, dull, or adamantine. For example, talc has a pearly luster, while quartz can have a vitreous luster.
Luster is an important property in mineralogy and materials science as it can help identify minerals and assess their potential uses in various applications.
