The Effect of Age on the Strength of Commercial Glassware

JSGT 1932 V16 T350-T359

The thermal endurance, bursting pressure, and impact strength of several groups of glassware stored (a) in a warm, dry, atmosphere, and (b) in the open without cover, were determined at various ages from 0·2 to 28 days; one group was tested for thermal endurance at various times up to 4 months after manufacture. No indication of change in the strength of the articles was found exceeding the probable error of the tests at any age up to 4 months.
