O...BOOM.
I learned my lesson and I was not in the kitchen when it happened (Thank God)
We just had the crock roast that night.
I've never tried the dumplings again.
You need to look for "vintage" pyrex. The good stuff!
"When World Kitchen took over the Pyrex brand, it started making more products out of prestressed soda-lime glass instead of borosilicate. With pre-stressed, or tempered, glass, the surface is under compression from forces inside the glass. It is stronger than borosilicate glass, but when it's heated, it still expands as much as ordinary glass does. It doesn't shatter immediately, because the expansion first acts only to release some of the built-in stress. But only up to a point.

"It turns out that this mixing bowl is not made by corel, and is not the high quality high temperature glass originally used. Corel sold of it's Pyrex brand to another company called World Kitchen. WK uses common bottle glass for all it's Pyrex line, rather than the 'lab glass' that made pyrex worth buying.
I was forced to purchase a replacement for the 16 year loyal pyrex measuring that finaly broke. It arrived today, complete with defective bubbles and cracks through both the handle and bowl. Return shipping will cost more than the item did to purchase, so I am out of luck.
If you are looking for the quality pyrex that has been used for generations, you are out of luck. It has not been made for a while now."
