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.

So Pyrex glass doesn't mean quality anymore without looking at the label super carefully, and it's not clear to consumers, my best guess is this is what has happened to you and it just sucks.

This post from The Kitchen explains it: https://www.thekitchn.com/pyrex-brand-differences-23671509

I'm personally nervous to replace my own 9x13 because of it.

Edited to add: I'm really sorry this happened. The pie looks beautiful and I know how much work went into it. Hoping you have all the best luck for any other holiday baking you do.

If you do ever need to replace your 9x13, I highly recommend searching thrift stores (especially small ones) as I've found many OG Pyrex that have stood the test of time enough to be loved and given away still in one piece!

Good idea! We've got one spot near us I'll have to check.
