Thermal shock explosion from 425* pyrex
coming to contact with 80* pyrex.

A very loud bang and glass shards shot everywhere
in an 8 foot diameter.

A perfectly good pork roast. I salvaged it. The glass blew
in a horizontal sweep.

must have had a flaw Dale, just be careful when eating it
 
Better get 5 or 6 extra pyrex pans to keep in a cabinet in case another explodes....hehehehe
 
Amazing how pyrex will do that. Had a similar thing happen in a similar situation......
 
Triumph didn't make that pan, did they Dale?

Sorry, I couldn't resist :angel:

Well, there ya go - 2 examples...better pull all the Pyrex from the cabinets & replace with something else....or get a huge stock of spare Pyrex....hehehehe
 
Do y'all know what pyrex was originally made for though? Huh? Do ya?
 
don't know, Scott but I have a sneaking suspicion you are going to tell us :laugh:
 
I understand the stuff was originally designed for use as headlamps on steam locomotives.
 
Ah! very cool. was it for carbide lamps or oil?
 
Was that a Dow Corning pan? How old was it? In doing some looking, turns out the Pyrex glass made by Dow Corning changed from borosilicate glass to tempered soda lime glass. Arc International still makes Pyrex glass with borosilicate glass. Looks like when it comes time to replace my pans, I'll buy Arc International.
 
Had that happen with a tempered drinking glass while visiting the parents. Pulled it out of the cabnet put it down turned around to grab something else and BOOM glass everywhere. My mom still complains about finding glass bits in the wierdist places in the kitchen.

Bet that Pyrex came from WalMart. They really don't make'em like they used to. Be willing to bet it ain't Corning.

I don't know. I think it was on the show "modern marvels" or something like that. It's one of those tidbits that makes you go "hmm".
 
Glass is scary stuff. Liquid.
 
Just ask the guy who used the environmental chamber here at work. Apparently he opened the door while it was cranked up to a high temperature inside, and the room temperature shattered the window in the door. It's intact, but a little hard to see through now. Got his attention when it shattered though.

Yup Doc! Most folks do not know that. No crystaline
structure at all. Very old window pane glass can often
be seen with slow motion drips.

The blown up pyrex dish was about 12 to 15 years of age,
so it's doubtful it was foreign made.

Thankfully the stovetop pyrex did not blow up. We paid
$700 bucks for it 13 years ago.

Finished the roast in a steel pan.

The exploding pan probably was objecting to the normal scratches, drops, bangs and whatever happens during normal use.
 
When I worked as a bartender years ago once in a great while we would have glasses explode. We always used a fresh glass, never re-filled. It was a really high volume bar and the glasses were subjected to repeated heating and cooling as they went from cold drink to automatic washer/sanitizer, back to cold drink, cycle after cycle, night after night. Sometimes it would happen right as they came out of the washer and sometimes it would be right after they had been filled with a fresh drink.

It was great fun to watch the reactions from the patrons. Some would foolishly swear to their mates they hadn't touched it - it just blew up! Others would quietly look around to see if anyone else had seen it, apologize and politely ask for another. And occasionally you'd have one simply ask to clear his tab. After playing them a couple of minutes I'd let them off the hook and fess up that yes, every once in a great while one of the glasses would explode.
 
Ten years ago I flew up to a construction site in
Maryland during the screeching hot summer.

The project foreman had recently purchased a
shiny black, fancy truck. At the end of the 107*
day, we all walked over to view his new ride.

He leaned on the front, driver's fender and suddenly
a loud BANG was followed by his drivers window exploding
into thousands of little cubes of glass.

One of the strangest things I've ever seen.
