That is the older version of Corningware, and in it's many forms highly collectable as well.
Sometime before production began waning, Corningware stopped making range top safe dishes, and only oven and microwave safe. Many a housewive and others not reading the bottom of their Corningware dish assumed it was the same they always had and put it on top of the range, only to have the thing shatter to bits. There was some very furious raised voices I can tell you on the matter.
Old Corningware does have a following, with some women today having tons of it as either gifts, or inherited from various female family members. Some use it to death, others allow it to sit lingering in cupboards.
Shame really, compared to the cheap plastic tat sold today for freezer to microwave use, Corningware is streets ahead. Oh, an let's not get started on the horrors of heating foods in plastic containers when using a microwave.
