Rock salt, also known as halite, is a natural mineral form of sodium chloride. It is commonly found in large deposits underground and is often harvested through mining. Rock salt is typically used for various purposes, including de-icing roads in winter, as a seasoning in cooking, and in the production of table salt. In addition to its practical uses, rock salt has a unique crystalline structure that makes it visually appealing. It can be found in different colors, ranging from clear to shades of pink and blue, depending on the impurities present. This makes rock salt not only functional but also a popular choice for decorative purposes in homes and gardens.
