Process for the preparation of glass making batches

Claim 1

IN THE PREPARATION OF A GLASS-MAKING BATCH CONTAINING SAND AND SODIUM CARBONATE IN QUANTITIES EFFECTIVE TO FORM GLASS, THE IMPROVEMENT WHICH COMPRISES PROVIDING IN SAID BATCH A FREE LIQUID VOLUME OF FROM 5 TO 30 LITRES PER METRIC TON OF BATCH EFFETIVE TO PROVIDE AND PRESERVE IN SAID BATCH, AT STORING TEMPERATURES LOWER THAN 35*C., A SUFFICIENTLY MOIST STATE TO IMPART TO SAID BATCH IMPROVED PROPERTIES FOR STORING AND USE, SAID LIQUID VOLUME BEING PROVIDED BY THE STEPS WHICH COMPRISE ADDING TO SAID BATCH A QUANTITY OF CAUSTIC SODA RANGING FROM ABOUT 0.05 TO 1.19 KG. PER LITRE OF SAID VOLUME THE MINIMUM QUANTITY OF SAID CAUSTIC SODA BEING ABOUT 0.05 KG. FOR A STORAGE TEMPERATURE OF ABOUT 33*C. AND ABOUT 0.30 KG. FOR A STORAGE TEMPERATURE OF ABOUT 0*C. AND THE MAXIMUM QUANTITY OF SAID CAUSTIC SODA BEING ABOUT 0.49 KG. FOR A STORAGE TEMPERATURE OF ABOUT 0*C. AND 1.19 KG. FOR A STORAGE TEMPERATURE OF ABOUT 35*C., ADDING TO SAID BATCH A QUANTITY OF WATER RANGING FROM ABOUT 1.0 TO 0.53 KG. PER LITRE OF SAID LIQUID VOLUME, AND ADDING TO SAID BATCH FOR A STORAGE TEMPERATURE BELOW ABOUT 15*C. AND FOR A STORAGE TEMPERATURE ABOVE 15*C. WHEN SAID QUANTITY OF CAUSTIC SODA IS IN THE RANGE OF ABOUT 0.05 KG. TO 0.49 KG. PER LITRE OF SAID LIQUID VOLUME AN ADDITIONAL QUANTITY OF WATER NECESSARY TO CONVERT SAID SODIUM CARBONATE IN SAID BATCH INTO SODIUM CARBONATE MONOHYDRATE.
