How are glass beads classified?
Glass beads are made by firing glass sand. Glass beads can be divided into glass microbeads (glass microbeads are a type of glass beads, referring to solid spheres with a particle diameter of less than 1 mm) and glass beads.

According to the punishment, it can be divided into glass beads for reflection, glass beads for sandblasting and shot blasting, glass beads for grinding, and glass beads for filling. .
According to the refractive index, it can be divided into general refractive index and high refractive index glass beads. The general refractive index is between 1.5-1.64, and the high refractive index is generally 1.8-2.2.
Assuming that the most suitable for reflection is glass beads with a refractive index of 1.93, this refractive index can be satisfactorily refracted back to parallel light, so it is not that the higher the refractive index, the better the reflective effect. According to the shape, it can be divided into regular glass beads and irregular glass beads. According to the color, it can also be divided into colorful glass beads and colorless transparent glass beads.
