Measuring Up?

Apparently there’s a lot to learn about Pyrex. Specifically, PYREX (all caps) vs. pyrex (lower case). The former is vintage and made with borosilicate which makes it a lot sturdier as far as withstanding temperature variations, i.e., "freezer to oven". The latter, pyrex, is newer and now made with soda lime ash which has higher impact resistance (they no longer claim to have freezer to oven capability).  None of this mattered to me last week when all I wanted to buy was a 2 cup Pyrex measuring cup. My "old trusty" had broken when I accidentally dropped something else on top of it.  I figured I could cruise into my local WalMart easy enough and grab one off the shelf. Nope. Think again. WalMart, Ace Hardware, Target... nope, nope, nope. I could find plastic measuring cups everywhere but that's not what I wanted. For fifty+ years I have kept 1 cup, 2 cup and 4 cup Pyrex measuring vessels in my kitchen cabinet; not sure I could prepare meals without them. The girl that I asked in Target said that they stocked Anchor brand to avoid the controversy. Huh? That's what sent me to the Internet to research what was up with Pyrex. A quick check of our baking dishes on hand here at the house revealed a pretty even split between PYREX and pyrex. ( I even have a few PYREX "Flameware" dishes which belonged to my in-laws, they can be used on the stovetop, but that's an entirely different matter.) Whatever. I like to use a Pyrex measuring cup for measuring liquids, reheating gravy, sauces or melting butter in the microwave and for cooking in general. I found one on Amazon. I'd better hang on to it. You know, with all that controversy and so forth. There might be a lot that I'm missing here, and that's okay with me; I found my measuring cup and that's all that I was looking for.

Oh dear! I never knew about the controversy. I’m going to have to check out my Pyrexware. I can’t imagine living without those three measuring cups. A few years ago Costco sold them in a set of three. I would not have thought they would be that hard to find these days. Guess I’d better be extra careful with mine.

My youngest son, who is quite a good cook, informed me about the capital PYREX vs. the lower case pyrex when he was here for a visit sometime last year. I never knew. But when I look down at mine in the pull-out cabinet, I can see the blue tinge in the glass of the newer ones. In my "soap kitchen" I have a set (1 c., 2 c., 4 c., and 8 c.) of the PYREX that I have used in my soap making for 30 years. In my baking cabinet I have two of each of those sizes. But half of those are the pyrex, not PYREX. I am keeping my eyes open in secondhand stores and antique malls!

Who knew? I'm going to check the 1 cup and 4 cups that I have in my cabinets. I will be watching thrift stores to see what I can find!
