Is corning-ware safe under the broiler?

Answer 1

In short the answer is that the older white Corning dishes and the Visions dishes (but not the pot lids) can easily handle being placed directly under the broiler and take direct heat!

The newer Corningware, produced since 2000, CAN NOT BE placed under the broiler or take direct heat. Nor can any Pyrex bakeware dishes!

Again the proper answer depends upon the Corning Ware being used. Corning the glass-maker in the mid-1950's came out with its Pyroceram glass-ceramic white cookware - "Corning Ware" with the little blue flower and later other patterns. Millions of these items were produced. Corning Ware made from a material intended for missile cones (handling temperature extremes way above and below those found in our regular kitchens) could go directly from freezer to hot oven to stove-top to the microwave oven to table to fridge to the broiler to the dishwasher, etc. Extreme temperature changes did not affect the very durable cookware, such that the Corning company issued its cookware with 10-year warranties for replacement if breakage occurred. Corning the company only issued 2-year warranties on its Pyrex products if heat related breakage occurred. The Pyroceram cookware was very tough stuff. So yes, the Pyroceram Corning Ware cookware could go direct from the freezer to the hot oven - there would be NO DAMAGE to the cookware in such a practice. Pyroceram based Corning Ware often has markings on the bottom or near the handles concerning stove-top, oven, fridge and freezer usage.

Just to be inclusive, in the 1990's Corning produced a series of Visions cookware, brown amber and cranberry colored glass-ceramic dishes and casseroles, that had the same basic properties of its white Pyroceram cookware. Visions cookware could go directly from freezer to hot oven to stove-top to the microwave oven to table to fridge to the broiler to the dishwasher, etc. Extreme temperature changes did not affect the very durable cookware, While many folks mistake Visions cookware for Pyrex bake-ware, they are not the same. Visions cookware was never issued in the forms (square pans, rectangle baking pans, loaf pans, pie pans, etc that clear glass Pyrex baking pans had been produced in for decades. In any case, Visions glass-ceramic cookware could go direct from the freezer to the hot oven - there would be NO DAMAGE to the cookware in such a practice. Visions glass-ceramic cookware also has markings to indicate usage. The majority of Visions cookware were of the "stove pot" design - stove top was intended from the start. I've place my Visions skillet under the broiler hundreds of times!

In about 1998, Corning the company sold its housewares division to World Kitchen, who was now licensed to produce cookware under the Corningware name and brand. A short time after the sale, the production of Pyroceram based Corning Ware cookware and the Visions cookware ceased. World Kitchen brought to market and to this day produces a series of stoneware casserole dishes it called Corningware, some in bright colors. These stoneware dishes could go from freezer to hot oven to the microwave oven to table to fridge to the dishwasher -- just not directly! Extreme temperature changes are not good for stoneware, nor can such stoneware dishes be used on the stove-top, the toaster oven or under the broiler - NO direct heat usages. The current stoneware dishes usually have a coarse unglazed ring on the bottom of the cookware, and will indicate no stove-top or broiler usage. The stoneware dishes were intended to be used in the oven - conventional gas or electric, microwave, convection, etc.

In short the older Pyroceram Corning Wae and the Visions cookware can handle it, the new Corningware stoneware products can not.

One very important note - all of the pot and casserole lids of Corning Ware (old stuff), Corningware (new stuff), and Visions are made of Pyrex! Pyrex pot and casserole lids) and Pyrex bake-ware (roasting pans, baking pans, pie plates, loaf pans, etc) simply CAN NOT handle the direct heat of broiler, or the stove-top or a toaster oven! Usually under a broiler there is no need to cover the dish in any case! Basically the "base" parts, the older white Corning Ware dishes and Visions dishes can handle the broiler. However the newer stoneware Corningware and Pyrex can not handle the broiler, toaster oven or other direct heat.

Answer 2

No, it is advised one does not use Corningware under a broiler. The glass used in these dishes cannot withstand the heat of the broiler.

Answer 3

I don't think so.

Answer 4

Yes
