More interesting to me is the same issue with CorningWare[1]. I've used this for microwaving food for decades and I've bought a lot of it off ebay. In fact, that's all I've used ebay for in the last 10+ years. According to the wikipedia page, it suffers from the same borosilicate vs soda-lime issue.

Corning is one of the companies they are discussing in the article

To be clear: it's the lids that would involve this issue, not the Corningware pieces themselves. Those are a glass ceramic (a kind of glass converted, by heating, to a microcrystalline ceramic.)
