I saw a news report on the potential dangers of Pyrex glass bakeware shattering at home. They cited a Consumer Reports study that was done and the video footage of their testing is pretty dramatic. They found that newer Pyrex sold in the U.S. is made from soda lime glass and no longer borosilicate glass like how vintage Pyrex was made. Soda lime glass will shatter once taken from normal oven temperatures and placed on a wet countertop which "shocks" the glass and causes it to shatter. I don't know if shatter is the right word, I'd almost call it "explode." Cook's Country (part of America's Test Kitchen) also admitted having the same experience with their Pyrex glass exploding from oven to counter on their Season 4 episode: "Not Just for Kids."
This doesn't mean you have to get rid of your Pyrex bakeware but you just need to be careful to place hot glassware on a trivet or dish towel (which is always a good idea anyway). But if you're an absent-minded cook it might be a good idea to get a new baking dish. Cook's Country tested several baking dishes specifically for broiler usage because this is obviously the highest temperature that the bakeware would need to withstand. They tested several materials like ceramic to cast iron and found that all the products performed the same. The only dividing factor was design. Cast iron was much too heavy and some product handles had only a thin lip or no handle at all! In the end they suggested the HIC Ceramic Lasagna Pan which is lightweight and has very grip-able wide handles.
