Cutting Pyrex
My wife just bought some new pyrex baking pans , and the one we want to
use is just a hair too long to close the oven door on - this is a small oven in a camper . My question is can I cut the little bit off so we can use it , or will it shatter like tempered glass ? I have both a wet saw for tile and wet/dry diamond and masonry cutting discs for my angle grinder . I think the best choice will be the tile saw ... but I've been wrong before . -- Snag |

As I recall reading a few years ago, today's Pyrex is not your Grandmother's Pyrex. The company changed hands and today's Pyrex is no longer tempered glass. Paul |

Yes you can cut it the same as regular glass. When glasses are made or heated to the melting point, tempering is just slow cooling to avoid built in stresses from cooling too fast. The surface glass should not be much different than the interior. |

Snag Screw around with that annealed edge on that handle may result in the whole shebang shattering when it gets hot. Keep that in mind. Best to buy a pan that fits the oven IMHO. |

It's tempered glass all right, just not _borosilicate_ glass of the original Corning products. The trademark has been licensed to several manufacturers, a few of the smaller of which still do use borosilicate glass but the primary one doesn't. World Kitchen iirc is the spinoff of Corning that uses a clear tempered soda-lime glass instead because it's less expensive. It also isn't as heat-stress resistant and there've been some complaints... -- |

If you try it, safety glasses and gloves. At least you'll be able to follow up here if it goes sour. |

YMMV Back when I was in school, I would cut glass tubing of much smaller diameter by scouring with a file, breaking and polishing ends by abraiding with a piece of metal screen. Also did some simple glass blowing with Pyrex like repairing flasks or attaching joints. Would temper by diminishing flame and slowly removing to get out stresses. Was not hard to work with. |

This guy gives some tips. Dispels myths of cutting glass bottles, making drinking glasses from empty bottles. Neat method he uses. https://www.youtube.com/watch?v=sFXngPx3w3M |
