I’m not fond of plastic.  I know that it’s necessary in today’s world, and there are a lot of things that I love that are made of plastic (like much of my computer), but if I could replace these plastic things with equals made of wood, glass, or metal, I would.

Corning Incorporated first developed Pyrex in 1915.  At first it was developed for scientific and industrial purposes, but according to Pyrex’s own website, when the wife of one of Pyrex’s scientists became frustrated with her own unreliable casserole dish…  Well, the rest is history.

This stuff is really a triumph of science.  It is as clear as regular glass but can withstand much higher temperatures than untempered glass.  Although untempered glass is not at all recommended for oven use, tempered glass is considered safe in temperatures as high as 425°F.

So what’s the catch?  Is Pyrex more brittle?  Surprisingly no.  Tempered glass is considered 4 to 6 times more impact resistant than normal glass.

Some time ago, my wife and I got a set of Pyrex bowls with plastic tops.  This was partially to replace the mountains of Tupperware growing in our kitchen.  Glass is much easier to clean and has a nice look in the fridge.  We were also growing concerned about BPA leakage in plastic food containers, but you may do your own research on that.

Pyrex cookware is no longer owned by Corning Incorporated.  In 1998, the consumer products division was sold off to World Kitchen, based in Rosemont, Illinois.  Despite rumors stating otherwise, they continue to manufacture all of their cookware for the American market right here in the United States. So what’s Corning doing now? Check your phone.

Forgive me for making assumptions.  Perhaps you were working late in the lab last night and you accidentally broke your only Erlenmeyer flask.  I’m happy to report that Corning is still in the market of making fine laboratory glass, though not all domestically.  According to their website, they have five factories for laboratory glass; three are in the United States.
