Hi been lurking around but couldn't help chime in here as the topic touches on a mild obsession I have with retro cookware and lost technology
Re: Corningware and Pyrex.
Pyrex and Corningware were both amazing products in thier versatility and durability.
There is a reason that these could be found in almost any American kitchen. They may not have been the finest tuned chef's equipment but they were incredibly useful.
they can go in freezer oven and microwave and Corningware can go on the stovetop as well (although extreem temp changes can cause breakage in any glass.
I trust no other glass bakeware (ok some Ancho Hocking)
but beware the NEW cookware carrying the namesake Pyrex and Corningware are not the same product. The new Corningware is simple stoneware and the "Pyrex" is simple soda lime glass (see wikipedia) these products are Asian made and have NOTHING to do with the original scientifically advanced glassware made by the Owens Corning Corp.
I started collecting this stuff on accident due to simple need and thrift store budget. (I lost all my fancy kitchen stuff along with my X) The combination of function and nostolgia won me over completely. It is sad that a quality product has been lost to marketing and is no longer made at all.
For a couple bucks at a thift store or flea market you can by cookware that it simply not made anymore.
Sort of like properly ground cast iron pans....
