Unmitigated food disaster
After preparing and partially boiling vegetables and meat, they were then
put in a large glass bowl and it was placed on top of a gas hob to bring them to the boil. That was prior to placing it in the oven to make an oven casserole. This practice has been done by me quite a few times before. I've always assumed that a Pyrex bowl can be placed on a gas ring and the contents boiled, because someone I know has Pyrex glass saucepans, that they use to boil things in. However the wife doesn't think that these glass bowls should undergo this kind of treatment on top of the gas rings. Today using a smoky dark coloured glass bowl which I don't think I've used before, but I really thought it was an oven proofed bowl. It suddenly completely collapsed into pieces as I placed it in the oven. What a mess......... My question is not whether this was really an oven proofed glass dish, since i guess we will never know for sure. But is the wife right in saying this is a very *risky* procedure, putting a pyrex glass bowl over a gas ring to boil things? Even though i always start on the minimum heat so as to minimize any strains on the glass. So would you think that this is safe to do, or not? Thanks. |

Pyrex doesn't imply a particular type of glass. Originally it was borosilicate glass, but it's now just used as a well-known trade name to sell various different types of glass. Different companies use the name differently in different parts of the world. Borosilicate glass tends to be used for higher temperature applications, although I don't know what glass saucepans are made of. Even soda-lime glass (used for most glass applications) shouldn't melt in an ordinary domestic oven. Sometimes it's toughened - did it break like a toughened windscreen shattering? -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

And being more localised might result in even more stresses. Trying using a microwave oven instead. Or a different vessel. -- Bartc |

Sorry to go off topic, and not wanting to hijack the thread, but why did you do it? Was it to try to cut down on the time it would be in the oven? |

If one part is much hotter than another, as can happen with gas when the bit with water in stays at 100C but eh bit above water goes higher, thermal expansion can crack the top off in a neat ring. Pyrex is a low thermal coefficient of expansion glass. That's all. So you can pour boiling water into it and it wont crack. |

It might even have a symbol or warning on the bottom of that bowl that it's not to be used over an open flame. nancy |

The heat stress from applying a flame to a glass bowl is much higher because the high temperature is much higher: 3500F for a methane flame vs 500 at most for the oven. Pyrex made a "Visions" line of glass saucepans -- try to find one of those. |

Clearly though, pyrex *bowls* are not designed to be put directly on a flame. Tim |

After having tried just about every pot and pan ever made, I have settled on Stellar stainless steel with aluminium billets in the bases. These work well on gas, electric and the aga, and can be scrubbed clean with wire wool when she burns the porridge (again) Those, and a few le creuset slow cooking pots are all I use these days,. |

More recently I tried using one at my parent's house. My mom doesn't cook very often, doesn't have many pans and all of the ones she had were in use except for that one. I was heating gravy from a box and once again, it burned. I should add that I am not one of those people who burns food very often. Once in a while my rice will get too dry and it will stick a little to the pan. I did get rice burned to the bottom of the pan once. And occasionally I will burn a few pieces of popcorn. That has been all in the past probably 20 years or so. When I was younger I did burn things a few times. I can't remember the particulars now but I do remember using a method that I read about in some book. Cover the burned food with baking powder (quite a bit of it) then water then bring it to a boil. Let cool and most of the time the burned food will scrape right out. Once in a while you'll have to repeat this. This method has never failed me. |

I know has Pyrex glass saucepans, that they use to
boil things in. However the wife doesn't think that these glass bowls should undergo this kind of treatment on top of the gas rings.My question is not whether this was really an oven proofed glass dish, since i guess we will never know for sure.I 'wouldn't have dreamt of putting a Pyrex bowl directly on a gas hob.

IME the glass had so much thermal inertial that they were uncontrollable - took forever to heat up and then retained it for far too long after turning the heat off.
