I must be getting old, as today I dropped my Pyrex 1 Quart Measuring Cup from a cupboard about 10 feet up and guess what, it didn't break, and I was very excited! I've bought dozens of measuring cups over the years and have managed to melt, break, tarnish and mutilate each and every one of them. This one seems to be up to the challenge. I've used it to melt butter and left it in the microwave too long, washed it a dozen times in the dishwasher, used a whisk in it (I love the sheer size of this thing!). Not a scratch on it! I know, I know, it's just a measuring cup. But quality does matter, and this one is top notch!
