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. |

IANAE but apart from a specific glass saucepan, I 'wouldn't have dreamt of putting a Pyrex bowl directly on a gas hob. We regularly use ceramic ovenproof dishes, but again, I would not have considered putting them directly on the hob. Just my two-penneth FWIW. |

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. 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 |

Corning themselves changed to soda glass in the 1940s. Europe stayed with borosilicate because Corning licences production to J A Jobling who had some integrity. |

They did say that... ....the company's products now vended in the North American market are fashioned of tempered soda lime glass, a cheaper material. (The borosilicate glass version is still sold in Europe.) And the "undetermined" claim that Corning swapped to soda glass in the 1990s is way out. Corning themselves changed to soda glass in the 1940s. They said that, too... ....the brand's current owner, World Kitchen, claims that changeover began back in the 1940s and long antedates Corning's 1998 sale of the brand: The Charleroi [Pennsylvania] plant has produced PYREX glass products out of a heat-strengthened (tempered) soda lime glass for about 60 years, first by our predecessor Corning Incorporated... |

However AFAIK, Pyrex is borosilicate and should resist most attempts at domestic heating, anything else that doesn't have specific labels is assumed to be soda-lime and I wouldn't even think about heating it. |

The key is the expansion rate. 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. |

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. |

I have a Pyrex double boiler, that is fine with that kind of heat - but unless you're using laboratory grade material, risky is putting it nicely. You do love living dangerously! I hope you're prepared for some kitchen cleanup and a possible trip to the hospital if you continue your half-witted practice of exposing home grade Pyrex bowls to a flame. -- Today's mighty oak is just yesterday's nut that held its ground. |

For decades, everything I cooked came out of my big cast iron pot. A few years ago, I bought a little stainless steel pot which is mostly used for soup and steamed rice. I haven't felt much need for anything else until a few weeks ago when I bought a copper-clad aluminum pan to use for roasting coffee. I haven't used it for that yet, but works great on small batches of sunflower and pumpkin seeds. |

I can pick up a set of three handled pots of assorted sizes with lids from that series. I wonder if I should both? I HATE those things! I got a free one when they first came out. I don't recall now how I got it for free. I used it all of twice. The first time it was just for heating up some sort of canned vegetable. I didn't have a microwave yet. The second and the last time was to make a single serving of macaroni and cheese. From scratch. Both times the food burned and stuck to the pan. The mac and cheese was next to impossible to clean out of that pan. So I threw it out. 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. |

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. 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? The key is the expansion rate. 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. I was taught at a very early age that heating a beaker (borosilicate glass) with the aid of a Bunsen burner needed a spreader under it to diffuse the heat and spread it over a larger area . The spreader, as most of you probably know was a 6ins square of wire mesh with a round asbestos patch in the centre. this prevented the flame ( very high temp) impinging directly as a point source on the relatively cold bottom of the beaker with the obvious consequences.
