And, I have a tip for you. Make nice with the thrift workers. This particular girl remembers me and my taste and actually called me over as she found the second casserole dish. And don't just be nice so you find good scores. It always pays to be nice. There are enough rude and obnoxious people out there. Don't be one of them. :-)
And then I really scored when I found this set. It wasn't even being sold as a set. The pieces were priced individually. I think I squealed in delight when I saw this baby. It includes a 9x13, 8x8 (or 9x9) and a loaf pan. In near perfect condition.
I always use my small Pyrex bowls for salads. The one on the right is tiny, but it would also be good for dips.
And this set is different. I found the larger bowl and two small bowls for $2 total at a flea market. I have never seen this shape before, but I have trained my eyes to notice the colors and glass thickness of Pyrex. Sometimes I am fooled and have to look at the bottom for the Pyrex imprint. In fact, I always check the bottom, just to be sure. I don't even know if this set only has two small bowls (as opposed to four) or if only two small bowls survived the owners.
I have my tomatoes in the big bowl now, but I think the small bowls would be good for dips and salsa. (Does it seem like I eat a lot of dip?)
And this was my latest acquisition. I don't love the pattern, but that doesn't matter. And I don't think the lid is the original, although it has the Pyrex imprint.
I honestly use my Pyrex on a daily basis. In fact, I have gotten rid of some of my newer stuff to accommodate my growing vintage Pyrex collection. I use them for storing leftovers (in a small effort to steer away from plastics), serving, reheating food, baking, and eating.
Other important Pyrex information: If you can find a lid for your Pyrex, great! If not, I have seen a few stray lids for sale in the thrift store. I picked up two about a week ago for very cheap. Just look for the Pyrex imprint on the handle.
Also, don't put your vintage Pyrex in the dishwasher. Wash them by hand. The dishwasher can ruin the finish on your bowls. Certainly not worth it in my book. Just be careful not to drop the soapy dish! They can be slippery when wet. Lots of information can be found here with pattern references, age, and care.
