3. Glass beads Intrduction
Glass beads are usually flame flotation method, the flame float method is a secondary molding
method, the basic principle of flame flotation method is to break the waste glass into a certain size
of the particles, and in a certain way to the glass particles into the flame, In the role of the flame,
the glass particles soften, melting,molding, annealing then become glass beads.
