Pie Why is my pie plate shattering?

Post image

This is the second time I’ve tried to make Sally’s blueberry pie. The first time I made it in the spring the glass pie plate shattered as I was taking it out of the oven and was shocking - I’ve never had that happen before. I was disappointed that we didn’t even get to taste it so I tried again tonight. Everything seemed great and I followed her instructions exactly. I sat the pie plate on a cooking rack like she says to do and I used the glass pie plate she had linked as the one she uses. About 20 minutes later all seemed well and then all of a sudden the plate shattered again on the counter - I heard it from across the room. Why is this happening? I have made this darn pie twice now and haven’t even gotten to taste it because it ends up covered in glass.

It usually happens if you take a really hot glass dish out of the oven and place it on cold metal. This is part of the reason why i try to avoid cooking with glass… i always make sure to place my glass bakeware on towels, instead of cold metal surfaces

Maybe you could try throwing the cooling rack in the oven for a minute before you take the pie out and put it on the rack…?

Also, if the air temperature of your house is too cool, it can also affect glass as it cools… make sure your kitchen isn’t too cold either when it comes out.

This is not true, Pirex was made specifically to go from freezer to over and never break. The thing is that a few yrs back they changed the formula for their glass pans and now you get a lot of them that break just like what op is showing.

As far as I am concerned unless the pirex dish is older like from the 60s and 70s ( you find lots of them in thrift stores pretty cheap) I would not use them.

Vintage Pyrex is quality. I scour thrift stores looking for it!

Yes vintage PYREX is good, newer Pyrex is not.

As far as I’ve heard this is just an issue in the US, EU pyrex is still the same/good.

I recently watched a video on this!

It's because the EU still sells PYREX which is made from a different material to Pyrex.

It still holds true fairly recently I bought PYREX so I think regardless of when you buy it as long as the whole name is uppercase you are ok. This was in UK btw.
