Mineral glass is a type of glass made from silica and other natural minerals. It is known for its clarity and durability, making it a popular choice for various applications, including watch faces and camera lenses. Unlike plastic, mineral glass is more scratch-resistant, which helps maintain a clear view over time. This material is often used in high-quality products due to its ability to withstand wear and tear. While it is heavier than acrylic glass, its aesthetic appeal and resistance to scratches make it a favored option in luxury items, such as watches and optical devices.
