Will the colored glass beads sold by Tik Tok fade?

The colored glass beads sold by Tik Tok will fade. The color of glass beads is made of various metal oxides sintered at high temperature, but if the processing technology is not enough, the color will fade. The pores on the surface of glass beads are directional, and the false ones are relatively uniform. Like real glass beads, they are finished products, and fake ones will have conchoidal fracture, which makes it easier to distinguish between true and false.
