We produced the glass beads using a spherical vessel which is rotable with the mix ture of releasing agent and glass powder in a electric furnace (apparatus 1), a tubing apparatus of electric furnace which can be gravitated a cullet (apparatus 2) and a tubing apparatus which is dispersible glass powders with the flame of propane gas (apparatus 3). The substrates which are Korean sodium silicates glass 1, 2, boro silicates glass and lead silicates glass are used and the size of cullets is 60-300 mesh. In the results of experimental apparatus, the preferable temperature of apparatus 1 is 880$^{circ}C$, apparatus 2 is 980$^{circ}C$ and apparatus 3 is 1100$^{circ}C$. However, the method of apparatus 3 is more effective than the methods of apparatus 1 and 2 in view of treating time and rate of adhesion.
