I noticed this a few days ago in the local kitchen store and intended to post about it but forgot until I was reminded by today's America's Test Kitchen segment.
Pyrex has
changed the shape of the glass measures and it makes no sense to me.
They have also added solid red paint around half of the outside, which makes it more difficult to read the levels.
It's not so bad on the larger measures - the 8 cup or 4 cup but for the smaller 1 and 2 cup measures to me they are awkward to use.
They still make a 2 cup that is the traditional shape with straighter sides and red spots to indicate the graduated measurement levels.
I already have a large supply of every size of the traditional Pyrex measures, which I intend to keep using.
If anyone has only one and like the way it works, see if local stores have any of the "old" style still on hand and buy at least one backup.
Otherwise, watch yard sales and thrift stores and pick up what you may need in the future.
