I love old Pyrex bowls, especially the brightly coloured ones and nab them if I see them on my travels.
When we married in the late 60's, we got 13 Pyrex casserole dish wedding gifts, from 13 different people!!!! Wedding lists hadn't been thought of in those days, at least not in the circles that we mixed in. They all eventually broke, the last one survived until the late 90's.
