Eight minutes after I put a pan of brownies in the oven this morning, I heard what can only be described as a loud explosion. It sounded like a bomb went off. I peeked inside the oven to discover that my glass dish of brownie batter had shattered. Thank goodness I didn’t peak in moments earlier!


My first thought was, “now I don’t have dessert for the Super Bowl!” Naturally.

Then I spent over an hour just willing it to go away. After some extensive whining, complaining, soul searching and information gathering on Twitter and Facebook, I decided to attempt to clean it up by myself because Mr. How Sweet wouldn’t be home for a few hours.


I scraped up the batter (which was batter at first, but ended up “baking” on the oven floor) and as many pieces of glass as I could with a spatula. This was only after it took me about another hour to get the bottom rack off due to the batter “glue” and large shards of glass wedged in between.


[This is currently still sitting on our kitchen floor. I have separation anxiety.]

Then after getting that wretched rack out, I used the shop vac. Don’t worry, I wore oven mitts and sunglasses as goggles.

Here’s the details:

  • The dish was Pyrex, which I’ve used for years. Not anymore. I will never buy it again. I don’t believe it was a “fluke.” After doing some research, this actually happens often.
  • The oven temperature was on 350 degrees.
  • The dish was in the middle of the oven, touching nothing else.
  • The dish was room temperature when it went into the oven, not hot or cold.
  • The dish was fairly new. It didn’t have any (visible) cracks.
  • I just used it last week at a higher temperature (375), to bake cookie bars.
  • I’m not contacting the company, because I honestly don’t care what they will give me. I don’t want a coupon and I don’t want a new dish. I won’t ever use Pyrex or glass dishes again.

Now who wants a brownie?

    Oh no! It actually happened to my friend too with a Pyrex dish except she didn’t even get a chance to use it! She bought it brand new and put it through the dishwasher before her first use. Same story, loud explosion and she had to clean all the glass shards from her dishwasher! Glad you didn’t get hurt!

    Jessica I am so bummed to hear this happened to you. On a positive note, just think of how many people will be saved from such grief by you sharing your story. I have a casserole dish that is Anchor Hocking. I guess I will be checking around to see if their quality is any better. I use it a lot for things that aren’t baked. Rice Krispies treats, layered dips, etc. So, if it does have risks like Pyrex, I guess I can just use it for other things. :)

    I had a disaster with a macaroni casserole a few months ago. A client had given me her church recipe and said it was the best she’d ever tried. It overflowed into my oven without me knowing! By the time I realized it, I had burned milk and cheese covering every crevice of my oven. It was a bigger disaster than I can ever describe. I literally had to have a “Come to Jesus” moment because I was so angry that I could not bring myself to clean it up! To make it even worse I had 2 of them in there and they were made with all organic ingredients. One was to be for me and the other was for my aunt and uncle who are in their late 70s. Needless to say I threw that recipe away!!!!

    Same thing happened to me. I took a dessert out of the oven and set it aside to cool. About 15 minutes after that, the 8×8 Pyrex spontaneously shattered. Luckily, my daughter and I were across the room. I can’t believe these people can get away with selling such dangerous products.

    That’s a terrible mess to clean up! That has happened to me but with shrimp in my pyrex in the oven, I think it was the drastic temps in my situation.

    Everything that Valerie said above is what I’ve heard or read. The borosilicate bakeware from Europe is a bit better than the soda lime glass but some still shattered up to oven temps reaching 500 degrees. Since my shattered shrimp incident my pyrex bake ware has ever been exposed to temps past 375 degrees!

    Oh how horrible. I don’t use very much pyrex, except to melt chocolate. Guess I won’t be doing that! I use mainly stoneware baking pans and cookie sheets etc. I keep hoping to win the lottery (it would help if I actually played though) so that I could buy some Le Creuset. We have an outlet here, but they still are so expensive! I have seen a few pieces at TJMaxx, but of course they aren’t the ones I want!
    Keep up the baking!

    I never use pyrex in the oven. I was making a cheesecake and put a small pyrex dish with water in it to help keep the cheesecake moist. (first mistake was using pyrex for this job) It shattered in a 170 degree oven – and of course ruined my cheesecake.

My 9 y/o checks the oven often when I’m cooking something so I will definitely switch to something else! I guess I need to purchase some metal pans! Thanks again for the heads up, glad you were not hurt. And I would contact the company anyway, just so it’s on file. That’s the only way they will ever do anything to fix the problem.

My head was turned and my hands were fine since the dough seemed to take the impact. I’m glad you weren’t hurt either.

    Jessica,
    I absolutely LOVE our brownie pan. It is from Wilton. I love it so much that I’ve given it as a bridal shower gift (of course with brownie mix!) I believe that I have an 11X8 pan (I got it at Kohl’s), or Wilton has a 9X9 pan as well. Here’s the link:

    http://www.wilton.com/store/site/product.cfm?id=AF3CD56A-1E0B-C910-EA5C1DD65713BAD6&killnav=1

    Sorry about your mess! This brownie pan does WONDERS!!! Just don’t use a metal knife to cut the brownies, use a plastic one. That way the bottom of the pan doesn’t get scratched. We’ve had to buy two of them!

    Pyrex Hysteria! Wow, talk about a complete over-reaction! I’ve been using Pyrex for years and have on intention of stopping just because one person who’s blog I read had a pan break in the over.

    Yes, it was a nasty incident but hey stuff like that has the potential to happen every single day. Let’s not get crazy here folks. Sit back, do some deep breathing, relax. Then come back in a day or two and re-think it.

    I for one, am in no position financially to replace all my Pyrex and I don’t think anyone is going to buy it for me.

    With all the health concerns around plastic, glass is still by far the safer better bet.

      Hahaha… Michelle I must admit that I would probably have the exact same reaction if I saw this on a blog. I was actually a bit shocked at the responses too! My intention wasn’t to tell people to never use glass bakeware. However, being that it actually happened to me, I will gladly never use my Pyrex (or any glass dishes) again. I don’t care how expensive they are. It was a pretty terrible thing (I can’t stop thinking about if I had peeked in my oven 30 seconds earlier and got my face blown off), and I think if it’s something you’ve experienced it’s easy to say you won’t use it again. But I understand and probably would feel the same way you do if it had not happened to me.

    I’m obviously behind on my blog reading but this is the second Pyrex exploding incident I read about today. My best friends older brother had this happen to him on Valentine’s Day. He had just pulled the dish out of the oven and it exploded in his hand. He wasn’t injured, thankfully, but how scary!

    I won’t be using Pyrex any longer. Unfortunately I can’t afford the Le Creuset set yet, but I have some ceramic ones from Ikea that will now be the workhorses of my kitchen.
