Abstract
1282868 Glass-making batches IMPERIAL CHEMICAL INDUSTRIES Ltd 20 Oct 1969 [29 Nov 1968] 56783/68 Heading C1M A glass batch in pellet form is made by forming a wet mixture of aqueous NaOH solution with a source of CaO and a source of SiO 2 in the necessary proportions subsequently to form a glass, feeding the wet mixture to a heated rotating cylinder or drum and heating it therein to at least 110‹ C., thereby removing water and allowing the NaOH to react with silica, and discharging a dry, pelleted batch from the rotating cylinder or drum. Sodium carbonate may be included in the batch provided at least 50% of the Na 2 O required for the glass is' supplied by the aqueous NaOH. The NaOH solutions used preferably contain 30-75% by weight of sodium hydroxide. The sources of SiO 2 and CaO are preferably sand and limestone respectively.
