Glass manufacture from prereacted batch and composition
Abstract
Abstract THIS SPECIFICATION DISCLOSES A NON-DECREPTITATING, DRY, GLASS-MAKING BATCH COMPOSITION WHICH IS INFINITELY STORABLE, AND A METHOD FOR PREPARATION THEREOF, THE COMPOSITION BEING USEFUL IN PREPARING A FINAL GLASS PRODUCT HAVING FROM ABOUT 4 TO 20 WEIGHT PERCENT OF ALKALI METAL FLUX OXIDES THEREIN. THE BATCH IS CHARACTERIZED IN THAT AT LEAST 50 WEIGHT PERCENT OF SAID ALKALI METAL FLUX OXIDE CONCENTRATION IN THE FINAL GLASS PRODUCT IS DERIVED FROM AN ALKALI METAL HYDROXIDE AS A COMPONENT IN THE BATCH AND FURTHER CHARACTERIZED IN THAT THE BATCH IS IN A SUBSTANTIALLY REACTED DISCRETE FORM PRIOR TO MELTING. A SIGNIFICANTLY REDUCED MELTING AND FINING TIME AND A REDUCED SEED COUNT PER UNIT TIME IS OBTAINED, AMONG OTHER ADVANTAGES, FROM SAID GLASS MAKING BATCH.
