Common Sense and Glass Cookware
It has just been brought to my attention that Pyrex cookware has been receiving some attention from Consumer Reports via the Consumerist. I love glass cookware and I will continue to use my glassware for baking, however there are a few precautions one should always use. Glass, even tempered glass is fairly rigid and doesn’t conduct heat like metal, therefore it’s subject to what’s called thermal shock. If the glass is exposed to uneven temperature extremes, it will try to expand or contract unevenly and can crack or shatter.
Some of you are sitting there going, gee Heather this is all common sense. Maybe for you it is.
A lot of people have only used metal cookware, which can warp, but doesn’t have that tendency to shatter. Since this is Home Ec 101, I try to cover all the basics. Heck, I remember shortly after I graduated high school one of my roommates attempting to make macaroni and cheese in one of my glass dishes, on the stove top. It didn’t go as she planned. To be fair, I did more than my fair share of stupid things in that phase of my life....
