Title: Low Quality Lime Silicate glass, not the old pyrex
Review: Pyrex is no longer made by Corning, and it is no longer made of durable borosilicate glass. The name brand was sold off. Pyrex is made in asia of much cheaper lime silicate glass. I was researching bakeware recently because I wanted the best, and what you want is borosilicate. One brand I found is Marinex, it is made of what Pyrex USED to be made of-- borosilicate glass. This is the highest quality glass you can get for bakeware. Pyrex may not stand up to freezer to oven use. I have also read many accounts of pyrex developing micro cracks you can't see. These then fill with liquid in the oven, and POW, they shatter, injuring people at worst or ruining dinner at best. Buyer beware.
