Replacement of Potash with Soda Ash to Produce Economical and Durable Glass

Abstract

Potash had been used as a flux for the production of table-ware glass for a long time. Gradually with the passage of time it has become an expensive flux. It has increased the cost of molten glass. Therefore, commercial glass production is not feasible with the potash. The present study has been based on the replacement of potash with some cheaper flux like soda ash. Required results are achieved by using soda ash with some minor additions of aluminum oxide and boric acid. The glass with these modifications was proved to be more durable and economical than potash glass.
