※ To mention about the process briefly, glass powders and foaming agents are well mixed and then heat-treated at a proper temperature to manufacture cellular glass. During heat-treatment, glass powders should be sintered first and then foams are generated. To obtain foam formation, it is recommended that glass completely surrounds foaming agents and then foaming agents generate gases to make foams. To satisfy these conditions, glass type, particle size, foaming agent type, quantity, heating program etc. should be well controlled.

Cellular glass manufacturing process largely consists of glass production process and cellular glass manufacturing process. For raw glass, cellular glass can be manufactured using waste glass, but the property of final products depends on the quality of raw materials.
Thus, although using waste glass can save cost to produce products, it is not practical when the aspect of quality of products should be considered. Therefore, the manufacturing process introduced here starts with the raw glass manufacturing process of our company, Ecocera.
