Just do not attempt to roast or microwave with them as the hazard is very clear. You may continue to use the soda lime dishes for holding stuff. I am not sure if the old Pryex dishes have anything stamped in them that indicates they are made by Corning. They have to be more than 25 years old to be sure they are indeed Corning dishes. If you own borosilicate Pryex dishes no fear. What a bunch of losers we all are for buying this crap. And they are the same price as the original Corning dishes. 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. The fine print does on and on about what you are not allowed to do with the Pyrex dish.
You cannot move a soda lime Pyrex dish from the freezer to the oven and expect it to survive. The instructions on the back tell another story. The label on the front says oven safe, freezer safe, microwave safe. Contrary to their denials the victims usually have more than one of these dishes and the Pryex logo is clearly visible. They say that the dishes are another brand, not theirs. Some dishes explode when they are lifted from the heating rack in the oven with devastating results. We were lucky because the dish broke while the oven was closed and the damage was limited to the oven cavity. Now it seems people are getting hurt using soda lime Pyrex. Corning not only sold the technology to a company called World Kitchen, they also sold the rights to the original Pyrex logo. Today, Wal-Mart is the largest distributor of Pryex products. The Chinese discovered that using soda lime glass was almost as good as borosilicate glass and a lot cheaper. This stuff is indestructible.īut like everything else, the Bottom Liners had a great idea: sell the technology to another company. The material they used is called borosilicate glass. Exploding Pyrex is very common.Ī long, long time ago in a country we all know and love was a company named Corning. I Googled exploding Pyrex dishes and got ten million hits.
We threw a disgusting frozen pizza in the oven and it cooked okay. The oven came up to temperature and cycled normally. I suspected the oven got too hot and the dish simply blew. Upon completion I ran the oven empty to see if the temperature controller was working okay. It took over an hour to clean up the goo. I let everything cool down and then scrubbed the oven with Simple Green and some hot soapy water. I then sucked the remains with the shop vac. I shoveled the glass and the now mashed potatoes into a bucket with two putty knives. However, this time she was nowhere near the stove when it blew. Normally, I am quick to inform Sylvia she did something stupid.
The roast beef (our first in many months) was peppered with small shards of very sharp glass. Sylvia opened the oven door and the Pyrex dish had shattered into a million pieces. The October 2009 e-mail missive reproduced below suggests that Pyrex brand glass bakeware products sold in recent years are unacceptably (even unsafely) susceptible to breakage in ordinary use, and that current Pyrex products are inferior because the Pyrex brand, having since been sold to another company, is now manufactured from cheaper materials:Ībout 5:30 PM there was a loud bang from the oven. Sometimes glass vessels are unable to take the stress of that uneven expansion and shatter. When glass changes temperature rapidly, it experiences thermal shock, a process wherein different parts of the material expand by different amounts. Such breakage has to do with the nature of glass, which is the material used in the manufacture of this type of bakeware. It is not unheard of for a Pyrex dish to suddenly “explode” (i.e., break apart in conjunction with a loud noise) while sitting in a hot oven or soon after it has been taken from one and is resting on a counter. Consumers have been noticing for years that sometimes their Pyrex brand cookware unexpectedly breaks during or shortly after use, often with such shatterings occurring in what seems like rather eruptive form.
