Hi Jaxs Mom! Actually, the older French White IS Pyroceram. The newer, made in China, French White, however, is stoneware. I highly recommend finding the older stuff. It's actually easier to find than one might think. 
It's sad that Pyrex stopped using borosilicate glass with their products. I find that if I'm careful with handling of the newer stuff, and not putting a hot dish out of the oven on a cold or hard surface you probably have a 99% chance of being ok. But you never know.
