Pyrex Problems

Pyrex Dishes--MUST READ

Here's Snopes web address to say this is true. also confirms it:


Got any new Pyrex dishes in your cooking utensils? This is a must


I Checked at Wall Mart and all the warnings are there.

About 5:30 PM there was a loud bang from the oven. Sylvia opened the

oven door and the Pyrex dish had shatt ered into a million pieces

The roast beef (our first in many months) was peppered with small

shards of very sharp glass. Normally,I am quick to inform Sylvia she

did something stupid. However,this time she was nowhere near the

stove when it blew. I shoveled the glass and the now mashed potatoes

into a bucket with two putty knives. I then sucked the remains with

the shop vac. I let everything cool down and then scrubbed the oven

with Simple Green and some hot soapy water. It took over an hour to

clean up the goo. Upon completion I ran the oven empty to see if the

temperature controller was working okay. I suspected the oven got

too hot and the dish simply blew. This was not the case however.

The oven came up to temperature and cycled normally. We threw a

disgusting frozen pizza in the oven and it cooked okay.

What is going on?

I Googled exploding Pyrex dishes and got ten million hits.

Exploding Pyrex is very common.

Here is the story.

A long, long time ago in a country we all know and love was a

company named Corning. They made Pryex dishes. The material they

used is called borosilicate glass. This stuf f is indestructible.

But like everything else, the Bottom Liners had a great idea: sell

the technology to another company. The Chinese discovered that using

soda lime glass was almost as good as borosilicate glass and a lot

cheaper. Today, Wal-Mart is the largest distributor of Pryex

products. Corning not only sold the technology to a company called

World Kitchen, they also sold the rights to the original Pyrex logo.

Seamless. The consumer will never know.

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 goes 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 becaus e 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.

What to do?

If you own borosilicate Pryex dishe s 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.

I strongly urge you not to use the s oda lime Pyrex for the oven,

stovetop or microwave. The slightest invisible crack is all it takes

to have a mess and a possible injury.

As to World Kitchen: them and their cheap dishes. In case

you are wondering: World Kitchen is not a USA c ompany.

Thanks Margaret W.
