Reflective glass powder is a special powder used to make reflective materials. These powders are usually made of glass or similar materials and have the ability to reflect light. They are often used in products such as traffic signs, road markings, vehicle license plates, high-visibility apparel, and more to enhance visibility at night or in low-visibility conditions.

Reflective glass powder works by reflecting light back to the light source, making it easier to see reflective objects at night or in low-light conditions. This effect is achieved through tiny dimples or reflective layers on the surface of the glass powder. When light hits these surfaces, it is scattered and reflected back to the source, increasing visibility.

Reflective glass powder is usually wear-resistant to maintain its reflective properties over extended periods of use. These powders can be added to paint, asphalt, plastics and other materials to create reflective signs and other reflective products
