Shattering glass cookware: New paper addresses causes; Margin of safety described as 'borderline'

In response to reports of explosive-like glass cookware failures, researchers applied basic materials engineering concepts to identify the causes. They found that current glass cookware sold in the United States is made of soda lime silicate glass rather than borosilcate glass used in the original Pyrex composition. They found that the soda lime silicate glass is much more susceptible to failure due to rapid temperature changes than borosilicate glass.
