Query: Cheap US manufactured garbage

I LOVE the OLD pyrex. It was the BEST but this new stuff is made in China and is garbage. If you are lucky enough to have some of the old bowls all you have to do is hold them next to the new ones and you will see the difference. The old ones are clear and the new ones have a blue cast to the glass. For some reason the blue tint in the glass weakens it but somehow makes it cheaper to produce. From what I've read all colored glass is more fragile especially when subjected to heat but I have to tell you, it also chips with just regular use. I've never had any of the old pyrex chip. I have many of the old ones and wanted to add more sizes. I was VERY disappointed. Also, the lids for the new ones are EXTREMELY stiff and very difficult to get on to the bowls. I even had one lid split because it would not stretch. Somehow this new stiffer plastic is cheaper to make just does not make a good product.
