Glass beads are made by firing glass sand. Glass beads can be divided into glass beads (glass beads is a kind of glass beads, refers to the particle size of 1 mm or less solid spheres) and glass beads according to the size. According to the use of points can be divided into reflective glass beads, sand blasting glass beads, grinding glass beads, filling glass beads. The reflective glass beads can be divided into reflective glass beads for safety and protection and glass beads for screen; according to the refractive index, they can be divided into general refractive index and high refractive index glass beads. General refractive index of 1.5-1.64, high refractive index is generally in 1.8-2.2, assuming that the most suitable for reflective use is 1.93 refractive index of glass beads, this refractive index can be satisfied with the refraction back to the parallel light, so it is not the higher the refractive index of the best reflective effect. According to the shape can be divided into regular glass beads and unruly glass beads. According to the colour can also be divided into colourful glass beads and colourless glass beads. Let's talk about the road reflective glass beads.

Yao Yong AAA glass beads can be used in clothing, shoes and hats, bead embroidery, glass beads lamps and handicrafts and other decorations, as well as, there are glass beads also known as glass sand, which is made from the general broken glass to stop the selection of different shapes and types of size. Famous colour glass beads glass beads that is the glass sand sintered in the gas furnace, most of them are round and spherical.
