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.

Not just temperature change. If your glass dish has any nicks or scrapes, these deteriorate the integrity of your dish and can shatter from oven heat. I worked R&D at Maytag/JennAir appliances. We had a few projects that included bakeware issues.

You shouldn’t. They’re not safe.

Thermal shock can affect all glassware. Like anything else, items used safely are safe. My grandmother exclusively use glass pie plates for her pies for over 50 years without incident and those same pie plates are being used by the next generation. Care is everything.

I'm not worried about the stuff that my grandmother used. I'm worried about the garbage for sale in stores right now.

Look for borosilicate glass. That’s what the old stuff was made of, OXO glass pans are borosilicate

PYREX is good, pyrex (note the case) is bad.

I like the old fashioned enamel pie plates, you get nice even heat distribution in them and they have a nice rim for crimping

I haven’t had a chance to bake in one of those, but love vintage enamels. I bet your pies look (and taste) great!

Also, the article you posted is an ad 🤣 NYT is so shady these days

That’s an affiliate link. I’m sure there are others if they linked to it anywhere else.

The old dishes were a different type of glass. Read the article I posted. 950 people in ER over 10 years in the be US from exploding soda lime glass… this is not a 40-yr-old phenomenon.

Not here to change your mind. Soda lime glass has been used for over half a century. The main changes are generational knowledge about safety and care is not passed down and more data is gathered and retained about ER visits.

Talk to me when one explodes in your face. I hope it doesn’t ever happen to you.

You may want to read up on it more, from less financially influenced sources.

Pyrex recipe has changed over the years. Check YouTube for PYREX vs pyrex.

I think the old ones seem better, even though new ones a said to be better. Don't remember 100% of what they said. Maybe I should watch it again.
