In this paper,a chemical treatment with potassium salts was used on the surface of the silicate container glasses.The effects of technological factors, such as sorts of salt,proportion,concentration,spray time,temperature and time ef heat treatment,were discussed.The result after hot and spray treatment in production line of container glass was analysed.It was found that a mixed spray solution(KCl:KNO_3=3:1)and a K_2HPO_4 spray so- lution have good tempering effects for container glass,and internal pressure...
