Hi, does anyone know what the glass is made from? I don't want it to explode like the Pyrex ones do

Glass cookware is subject to thermal shock. All glass cookware. Apparently Pyrex made some changes in the formulation which could have been responsible for some of the exploding glass. Other explosions (so to speak) could have been due to sudden temperature changes or immersion of a hot container into cold water or perhaps freezer to a preheated oven or cold, wet oven mitts. Read the manufacturer's instructions as these could vary from company to company or even casserole to casserole dish. No one wants a product which will explode on them, no one wants to make an emergency room visit. Follow instructions and use common sense. You can immerse a steel or aluminum pan and you won't see the tensile changes; you could with a hot glass dish.

I don't know the difference between different types of glass, but like Pyrex, I imagine similar caution needs to be taken. I wouldn't use the dish on top of the stove nor would I put a hot dish in cool water, ways that I myself broke 2 Pyrex dishes.

My guess is that they are the soda lime glass. Pyrex doesn't do much borosilicate glass in their kitchen cookware in the states. I hear that soda lime glass is a bit more resistant to breakage when dropping. In fact, these came in a box that was completely crushed, and a number of double wall metal pans were damaged and twisted out of shape very badly. The bowls survived without even a chip! Also judging from my mom's heavily used 20 year old set that is most probably made of soda lime (Pyrex switched in the 1940s), they can be very durable, and I don't expect any breakage.

It appears to be some kind of industrial plastic that doesn't melt. I only used the poacher once and I'm about to re-sell it so it's packed away at the moment. Sorry I'm not more helpful.

I have had two of the new Pyrex bowls explode. The first was when I was washing them in the sink prior to the first use. I placed the bowl in the strainer and it exploded. The second happened when my husband was heating it in the microwave just a few minutes ago. He took it out and said, it just melted and then it popped and exploded. I read an article that said that it was due to a change in the type of glass used as a cost cutting measure. I had emailed Pyrex after the first incident and never heard back from them. I think I will email them again, but I came here to look for an alternative as well. I'll look into Anchor Hocking. Thank you. I have had two of the new Pyrex bowls explode.

I have only had occasion to use these particular pieces in the microwave, however I have some older pyrex I've used in the over for many years. Thar being said, I researched this online and came up with this unconfirmed info: "Pyrex in US used to be made of borosilicate glass, now the Pyrex bakeware you see are made with soda lime glass. The Pyrex lab glassware are still made with borosilicate glass. In short borosilicate glass has a very low thermal expansion coefficient which is why scientists have little problem using these borosilicate lab glassware for chemical reactions. Not to say they will never break, but they are resistant to thermal shock. Soda lime glass is not. Therefore you hear all these US Pyrex bakeware breaking."

If they break easily, they are not borosilicate (think Pyrex) I've got Arcoroc bowls that are 30 years old. I was given some glass bowls that looked exactly the same, but they didn't have the "Arcoroc France" imprint. They were obviously fakes, none lasted more than a few months--same handling as the ones that are 30 years old. I just bought some Duralex bowls--they have an imprint are a little thicker than the Arcoroc bowls. It will be interesting to see if they hold up as well. If they can't take the dishwasher--they're fakes or just junk, they're more dangerous than useful. I think an imprint is a good indication if they're right or wrong.

I have the same problem.Very disappointing. Pyrex has a good reputation but I would not get another one from them

No, not in the year we've owned ours. We put food in them, freeze them (lids on), then put them straight in the microwave (lids off). We are not particularly gentle with them. However, as a glass artist, I'm going to tell you a secret: ANY glass CAN explode. It is an inherent danger of all glass. You get a particular kind of bubble when making it, or a scratch/chip from hard use, and then even a minor temperature differential can cause the glass to shatter. Manufactured glass almost never gets those bubbles. Most likely, that reviewer or her MIL (or someone at the store) had dropped the container and it had chipped or cracked, possibly without them noticing. This can happen to any glass, as I said. But it is rare. Look at all the glass in your kitchen, and in your friends' kitchens, and ask yourself how many times something has exploded, and that should give you an idea. Having a glass item explode, while very scary, is not as dangerous as it sounds. Other than fairly minor scratches/puncture wounds, the only real danger is your eyes. I wear goggles in the shop, and I've had several things explode. Outside the shop, though, I don't risk my eyes. And you shouldn't, either. For safety, you should always very carefully check any glass item after dropping it and, if it is chipped or cracked, even if it's very minor, toss it in the recycling bin. I know most people don't do this, and I know many times it doesn't explode even then. But there is that one time, when the crack or chip is in the right place, and the temperature differential is in the right place, where it will. Is it worth the risk to your eyes?

Don't know the prices. It was given to me as a gift. It exploded the first time I used it. Buy pyrex. This is dangerou

It's made of glass. Don't drop it. Don't try to eat it. Don't hit it with a hammer, etc.

very heavy glass. We had 2 that over heated and the glass melted and shattered, but did not explode and shoot glass all over.

Contact the company, Pyrex, to get a replacement? I wouldn't know exactly. Perhaps you will have to buy another same size container.

I don't know that but a call to Pyrex may help you. What I purchased was 2 quart measuring cups. I have since read that they may explode in the microwave so am not using them for the intended purpose.

I've had mine for several years, but they are glass. The only thing I've ever heated is butter to soften or melt without any problems.

I have years using it and it doesn't look like ceramic, is glass, but you should ask to the manufacture not to a consumer. I believe glass is safer than metal and non stick materials.

Glass, but not the toughest glass around.Be delicate with this kitEdit: im pretty sure its glass due to the way it cracked, just my guess.
