My parents got married 43 years ago yesterday, and one of my mom's most-cherished wedding presents was the Pyrex nested mixing bowl set she received.
I used the bowls last month, and they look brand-new. Part of it is my mom's good care over the years, but she used them an awful lot, so a tip of the hat to good-ol' Pyrex. I mean that literally. More like a tip to vintage Pyrex.
Back in the day, it was manufactured by Corning, but subsequently was sold and no longer made of borosilicate glass. It is easy to tell the difference. When I upgraded my mixing bowl set in 2000 (a mere two years after the fateful sale), I bought a set of nesting Pyrex bowls, but was sorely disappointed. They didn't have the heft, the gravitas, that my mom's set did. Or the handy lip to pour batter easily.
But all is not lost, thanks to the internet. Many people are offloading their mom's vintage Pyrex (anything before 1998 will do, but the retro styles are charming) on ebay for as little as $10 for a three-piece set.
So whaddaya waiting for?! Those Pyrex pieces aren't going to buy themselves!
