For example, a calculation published by the American Ceramic Society found that borosilicate glass can withstand a sudden temperature change of up to about degrees Fahrenheit, whereas tempered glass can withstand a temperature change of about degrees.
The publication references the tests performed by Consumer Reports , which used dry sand heated in casserole dishes. However, since sand gets much hotter than food, some experts say these tests which are often cited in news stories about Pyrex are too extreme and are not an accurate representation of durability under normal use.
According to excerpts provided to us by Hugh Rushing, former executive vice president of the CMA, the CMA tests suggest that glass bakeware should be able to withstand being abraded with sandpaper to simulate wear over time , heated in the oven for 20 minutes, and then submerged in a water bath with a temperature difference of degrees Fahrenheit.
This procedure was developed in conjunction with a committee of glass manufacturers and industry consultants, and it has been tested on a variety of glass samples from all the major glass producers, with the results submitted to an independent lab for analysis.
