Abstract

PURPOSE: To obtain tempered glass for a watch having high mechanical strength by contacting inorg. glass such as borosilicate glass to a K salt at a high temp. and applying ultrasonic waves to the glass to increase the ion exchange rate of chemical tempering treatment.
CONSTITUTION: Inorg. glass such as borosilicate glass is formed into a watch cover glass shape and finished to a mirror surface. This cover glass is preheated, e.g. to 410°C and held in a molten bath of a K salt such as KNO3 of the same temp. After applying ultrasonic waves the glass is allowed to cool, washed with water to remove the K salt, and dried. By this method the rate of chemical tempering treatment is increased, and a tempering effect higher than that of a conventional method is obtd. in a short time.
