The above Pyrex bowl doesn't quite count as 'vintage' IMHO. See, it was made in the 80's, and I was alive in the 80's, which means this can't possibly be vintage.
I originally started buying Pyrex because I wanted to try to minimize the amount of plastic we use in the kitchen. Containers with lids are a great (and much prettier!) substitute for tupperware.
I don't really make casseroles, but this shape is nice for holding muffins too, no?
And here's a picture of the blue bowl with purple grapes since my Mom requested it in the comments of my last Pyrex post...
We probably get the most use out of our big Pyrex mixing bowls. Fiona is quite the professional when it comes to mixing!
