 When Pyrex(公司名) cookware first came out, it was advertised as the ice box to oven, because itwas made of borosilicate glass which could weather large temperature changes without undergoing thermo-shock and shattering. But today, American’s Pyrex and Anchor Hocking(公司名) dishesare made of soda2 lime silicate1 glass, which is more prone3 to shatter. So, saysthe report of the bulletin of American ceramic4 society. Researchers have calculated that rapid temperature change, if just hundred degrees Fahrenheit5 could fracture the new glass compared to 330 degrees to for the old stuff. They saythat means that is possible to break glass measuring cup with boiling water orto explode a cool casserole dish by sliding it into a hot oven. Manufacturer says they temper(冶炼中专指通过锻炼增强材料性能) the new glass to make it stronger and researches did find some evidence for that. But they believe the heat treat is inadequate6, because in lab test cookware exploded into large glass sharps rather than tiny pieces as tempered auto-glassdoes. As the saying goes, if you can’t stand of the heat stay out of thekitchen. If this research is accurate that heat is on this cookware.
