What is Solid may have luster and is brittle?

A solid that may have luster and is brittle is typically a type of metal or a crystalline material. Metals like aluminum or tin can exhibit luster due to their reflective surfaces, while certain ceramics or crystalline solids, such as quartz, possess both luster and brittleness. Brittle materials tend to break or shatter under stress rather than deforming. Overall, the combination of luster and brittleness is characteristic of various materials across different categories.
