Glass Beads vs Crystal Beads
Crystal beads and glass beads are almost the same in composition, with glass as the main component. However, there are differences between them. Crystal beads are of high quality, high brightness, high density, and high refractive index, so they look more dazzling and clearer. Here are their differences:
Crystal beads:
- Material: Contains lead crystals, which contain lead oxide, which has better sparkle and clarity.
- Quality: Due to its excellent clarity, brightness and weight, it is of higher quality and more expensive than glass beads.
- Brilliance: Facets can reflect and refract light more effectively, and the reflective effect is better.
- Weight: Due to the lead content, crystal beads are denser and heavier than ordinary glass beads.
Glass beads:
- Material: Made from recycled glass.
- Quality: Varies greatly, related to the quality of the glass. Usually not as reflective as crystal beads, and lighter.
- Glitter: May not have the sparkle and clarity of crystal beads.
- Price: Affordable, with a variety of colors and styles, a large inventory, and a wide range of applications.
How Glass Beads Work in Increasing Traffic Visibility?
Reflective glass beads are a kind of spherical glass that is transparent and has the ability to refract light. So we use this physical property to apply it to traffic markings to improve visibility at night to prevent traffic accidents.
When the light from the car headlights hits the glass beads at a certain angle, the glass beads refract and then hit the surface of the glass bead cut surface. Then the refracted light will be reflected at a certain angle through the mirror surface to the driver’s eyes. The driver sees dazzling light. This is the working principle of glass microbeads.
