Higher strength glass containers by flame spraying

GT V31 1990 025-027

Low expansion glazes have been applied to the surface of glass containers using a flame spraying process. Four glass compositions have been characterised as potential glaze materials, a zinc borate glaze showing the most promise. This glaze was applied onto a large sample of containers which were then pressure tested. The bursting strength of the containers was significantly increased by the application of this glaze.
