摘要： When heating a glass gob including optical glass containing phosphorus, oxygen and fluorine to a temperature at which press-molding is possible, there are many cases in which the surface of the glass gob crystallizes and hardens. The problem of surface crystallization of glass gobs when press-molding is particularly prominent with glass to be polished and subjected to press-molding at a high temperature. This method for producing a glass molded article includes a step for covering the surface of a glass gob, which includes optical glass containing phosphorus, oxygen and fluorine, with a covering agent containing phosphorus, and a step for heating, softening and molding the glass gob covered by the covering agent.
