For example, a calculation published by the American Ceramic Society found that borosilicate glass can withstand a sudden temperature change of up to about 330 degrees Fahrenheit, whereas tempered glass can withstand a temperature change of about 100 degrees. The publication references the tests performed by Consumer Reports, which used dry sand heated in casserole dishes. However, since sand gets much hotter than food, some experts say these tests (which are often cited in news stories about Pyrex) are too extreme and are not an accurate representation of durability under normal use.
Borosilicate Glass has excellent thermal shock resistance. It does not expand and contract like ordinary glass does when exposed to rapid changes in heat or cold. Unfortunately when Corning, Inc. sold off the PYREX trademark it became pyrex in America and the new company started using Soda-Lime Glass instead of Borosilicate Glass. The company that bought the PYREX trademark for Europe continues to use Borosilicate Glass.
Now it seems people are getting hurt using soda lime Pyrex. We were lucky because the dish broke while the oven was closed and the damage was limited to the oven cavity. Others have been less fortunate. Some dishes explode when they are lifted from the heating rack in the oven with devastating results. Some people are heavily scarred. World Kitchen is in denial. They say that the dishes are another brand, not theirs. Contrary to their denials the victims usually have more than one of these dishes and the Pryex logo is clearly visible.
If you buy a Pryex dish beware. The label on the front says oven safe, freezer safe, microwave safe. The instructions on the back tell another story. You cannot move a soda lime Pyrex dish from the freezer to the oven and expect it to survive. The fine print does on and on about what you are not allowed to do with the Pyrex dish. The fine print has prevented World Kitchen from being sued because they have warned the consumer that their Pyrex dishes are junk from the get go. And they are the same price as the original Corning dishes. What a bunch of losers we all are for buying this crap.
If you own borosilicate Pryex dishes no fear. They have to be more than 25 years old to be sure they are indeed Corning dishes. I am not sure if the old Pryex dishes have anything stamped in them that indicates they are made by Corning. You may continue to use the soda lime dishes for holding stuff. Just do not attempt to roast or microwave with them as the hazard is very clear.
The reason the soda lime dishes let go is that over time they develop micro-cracks. Once a few micro-cracks are present and once some liquid finds its way into the cracks you have the bomb situation. The liquid is like shoving a crowbar in the dish and pulling it apart. Super heated liquids expand rapidly and it is the super heated liquids that force the soda lime glass to shatter into tens of thousands of shards.
Since Corning no longer makes Pyrex and Sylvia proudly holds a large collection of the soda lime Pyrex, we decided that one bomb in the kitchen is enough. The Pyrex dishes will go bye-bye in this week's trash. I do not know what we will use for cake and pie dishes going forward. If you have some suggestions we are listening.
The e-mail quoted above states that the writer \"Googled exploding Pyrex dishes and got ten million hits. Exploding Pyrex is very common.\" As noted above, all glass bakeware is subject to thermal shock breakage; when this type of sudden breakage occurs, especially when accompanied by a sharp, loud sound, it is commonly described by consumers as an \"explosion.\" The reference to \"ten million\" search hits is a gross exaggeration, but many accounts of sudden breakage incidents involving Pyrex brand glass bakeware can be found on the Internet and elsewhere: Chicago station WBBM-TV reported in 2008 that the Consumer Product Safety Commission (CPSC) had received 66 complaints about Pyrex incidents over the previous ten years and that the station \"counted approximately 300 more [complaints] reported over the last five years on consumer Web sites,\" particularly on the web site ConsumerAffairs.com, which has collected hundreds of reader-submitted complaints since 2006.
Soda lime glass is more common than borosilicate, especially in the US. For example, popular Pyrex glass storage containers and glass baking dishes are made from soda lime glass. World Kitchen acquired Pyrex in 1998. And that is when World Kitchen started making Pyrex lead free glassware from soda lime, not borosilicate. A lot of glass dinnerware options are made from soda lime glass as well.
It is unclear weather all of their old collections contain lead and cadmium, or is it just crystal glass.Their chef&sommelier collections are made from Maxima porcelain. Does anyone know what that is and are porcelain dishes considered safe (since it is fired on very high temperatires)
I have Corelle dishes and have 2 sets of Corelle mugs, one set is porcelain style Swept made in China the other Corelle made in Japan. Would these both likely contain lead What mugs would you suggest, glass by Duralex or Bormioli Also I had disposed of two crockpots that were 25 yrs old years ago and saved the clear glass lids. I sometimes use them as covers on Pyrex mixable bowls to microwave or store food, could these lids also contain lead I think the Crock pots were made by Hamilton Beach. Thank you.
Pyrex was born in Corning, New York. In 1908, Corning Glass Works began making a thermally resistant \"non-expansion\" glass for railroad lanterns and other industrial projects called Nonex. It found its way into the kitchen by a Corning employee. According to legend, the employee brought a sawed-off battery jar home and his wife used the shallow mold to bake a cake. After seeing how much money could be made by expanding the industrial use of Nonex, into the domestic sphere, Corning had a hit on its hands and the rest is Pyrex history. By 1915, housewives of America were buying Pyrex pie plates, casserole dishes and bakeware. Many people hung on to their Pyrex bakeware, but it's still quite popular today.
That means that the glass is more stable and when exposed to temperature fluctuations. Any dishes that you buy (used off Ebay or thrift stores) with the older PYREX label are made out of Borosilicate formulated glass.
There are lustrous chili bowls with handles, stackable refrigerator boxes, and casserole dishes set on top of brass candle warmers. These are durable dishes, often smaller than modern serving pieces, that can go from freezer to oven to table. But collectors usually acquire them for enjoyment, not utility.

This photo shows a Christmas ham that is sliced and put on a serving dish. The cooked ham is in a pyrex serving dish and has bowls of berries and a plate of cheese in the background. The table is brightly lit and covered with a festive Christmas tablecloth with a holly and berry design. A nice and healthy eating food shot with holiday motives. - A great shot for preparation cookbooks, ingredient, catalogs, chef, diet and cooking websites or magazines.
If you want to stick with the rectangular aesthetic, check out one of the best casserole dishes we've tested. Our favorite, the Great Jones Hot Dish, is dishwasher-safe, has handles that are easy to grip, and its retro design will look gorgeous on your dining room table when it's time to eat.
We recently tested two new casserole dishes from Great Jones and Made In, which weren't available at the time of our original testing. We compared both newcomers to the baking dish from HIC. While we don't recommend the Made In (you can read why towards the bottom of this page), we did really like the Great Jones Hot Dish and have added it as a new winner.
These flat, clear dishes will withstand repeated sterilization (wet or dry). The edges are beaded to provide greater mechanical strength. The bead also provides a means to equally space the side walls of the bottom and cover, thereby reducing the capillary action of condensed moisture on the sides. They are not affected chemically or thermally by any of the methods commonly employed in laboratories where sterilization is a major factor in routine or in specialized work. The covered dish is not airtight. The tops are marked in blue enamel and the bottoms in white enamel to make sorting easier. Bottoms also have a triangular, enamel reference point for serial dilutions.
You can also store and easily reheat dishes in glassware, without the risks associated with plastic storage containers. Glass cookware is usually dishwasher safe and looks great in the kitchen, assuming you keep it in good condition!
Some downsides of glass include uneven heat distribution (glass is a poor heat conductor), meaning that it is best suited to dishes like baked pasta, quick breads, and pot pies. It can also be hard to find glass replacements for all your cookware needs, but availability is improving as more people look for alternatives to non-stick cookware.
Pyrex is one of the best-known names in glass cookware, and for good reason. This glassware was originally made by the Corning Glass Company, which was founded in 1851 in Massachusetts. The company specialized in glass, ceramics, and similar materials for industrial, laboratory, and kitchen use. They made glass for telescope lenses, windshields, and for the familiar Pyrex measuring jugs, casserole dishes, lasagna pans, and other cookware.
