Abstract
This invention produces a batch of raw materials for glass making having a greatly increased speed of fusion and fining, by mixing a glass sand with quicklime and/or calcined dolomite and with caustic alkali with or without alkali metal salts. The batch may be made as a powder, a paste or may be formed into granules and dried. The batches can be stored without hardening.
