Just last night, I realized that my husband, who is newly interested in the kitchen, had left my Cobalt Pyrex baking dish in the oven through several bakings of other items. It was on the bottom shelf right by the burner and completely empty. (it was originally full of water to help steam some bread). After a total of nearly 5 hours of 350* to broiler temps of 500*, and hearing the stories of other people saying theirs had exploded, I was terrified to take it out of the oven, scorching hot.
However, it is completely fine! Not a chip or crack to be seen to my delight as this is my favorite and most used dish.

Looks good too and the blue color makes you less hungry, so you eat less!

My cobalt blue Pyrex baking dish exploded into a million little peices. I heard they have changed their process so the Pyrex name doesn't mean diddly any more. Stay away from this dangerous product! Buy good Pyrex at garage sales!

Durable with the Pyrex name. Beautiful color. Others have reported breaking but none to date.

One dish chipped after 1 week of use, but they are beautiful and nothing bad since.

While I love the color, I just found these reviews while looking for some purple bakeware to show someone what a baking caserole of mine looked like that just also exploded in the oven :(. I've got a couple blue casseroles like the ones in this set & now I'm going to be a little paranoid about using them.
Easy to clean though & mine did last over 5 years before it blew up (but a wicked mess when it went--I had chicken in 12 ounces of sauce in it--it went *everywhere* & I had the oven open to flip the chicken at the time--so my whole kitchen had glass shards in it...not pretty.)

The color is just beautiful, and of course it's great because it's Corning.

everything arrived on time if not before. Well packaged, so no damage. I would most definately purchase from this vendor again.

if you want to buy this color buy anchor bakeware it is so good

My cobalt pyrex baking dish, too, exploded in the oven, today while cooking a normal dinner. Do not use cobalt pyrex dishes. I have never heard of a clear dish doing this but see that many reviewers have had this happen with the cobalt.

While baking a basic brownie dish in the oven, my pyrex colbalt blue 9 x 13 pan exploded into 1000 little pieces in the oven. Nothing abnormal was done regarding temperature, greasing or any other questionable baking temperature changes. After reading others' comments I see I am not alone. Do not buy the tinted glass Pyrex, only the clear (never had a problem with clear).

I have been using Pyrex products for years and have always found them to be incredibly durable, sturdy and versatile.

I owned the rectangular casserole dish in cobalt for less than a month before it BROKE in the oven. I have the same product in clear, which I have owned for 7 years (as well as older versions of the same product that I inherited from my grandmother), and although I can not be certain that it is specifically the fact that this version is tinted cobalt that caused this problem, I can't ignore the fact that I haven't ever experienced this problem before with the clear ones AND the fact that apparently other reviewers have experienced the same thing.

If you purchase this product, just be careful. Hopefully you'll have more luck than I did!

I have had the exact same experience with the purple pyrex as "slevena" did. I have never experienced such crap before. They really need to fix this problem. I would not reccommend this or any similar products, it will probably ruin a mean in less than 1 year.

Excellent, although all pieces should come with lids!

I have owned two pieces of Pyrex Cobalt blue cooking dishes and both have exploded in the oven. I bought one piece two years ago and it exploded after a month while making Baked Ziti. I bought another piece this year from a different store and it exploded the first time I used it in the oven.

I studied to be a chef, use them under normal conditions and have never seen anything like this before

The sides of the dish blew out, there were shards of glass on top of the food, the bottom broke into fifty or more pieces. If I had opened the oven as it exploded chances are I would have been injured.

I haven't had this problem with any other pyrex dishes, just the blue dishes. Bottom line is two dishes, to dinners ruined, its not worth it to me to buy another.
