Method of strengthening glass articles with potassium fluoride-metal acetate |
| abstract |
ABSTRACT This invention is directed to a process for strengthening glass articles and, in particular, glass con-tainers such as beer bottles. The invention is directed to a process whereby the article is sprayed over its surface with a solution containing potassium fluoride and a metal acetate which prevents etching of the surface by the fluoride ions. The article is then treated at an elevated temperature to allow exchange of the potassium ions for the sodium ions in the glass. |
