Can Corning Ware be used for freezing?

Answer 1

Yes it can.

Answer 2

Yes - but it depends upon the dish.

Pyrex bake-ware does not like extreme temperature changes, such as directly from the freezer into a hot oven, or from a hot oven into cold water. Pyrex bake-ware (usually the clear glass variety) would often need a period of thawing out before placing frozen food into a hot oven. Pyrex bake-ware can not be used on the stove-top or under the broiler - no direct heat usages. However the question concerned Corning Ware, and Corning Ware and Pyrex are two different kinds of glasses, with different capabilities, and uses.

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 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. However it is practical to let the food defrost first, or adjust the cooking time in order to create a better thoroughly cooked dish.

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, 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. However it is practical to let the food defrost first, or adjust the cooking time in order to create a better thoroughly cooked dish.

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 or the broiler - not 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 usage. The stoneware dishes were intended to be used in the oven - conventional gas or electric, microwave, convection, etc. However it is practical to let the food defrost first, or adjust the cooking time in order to create a better thoroughly cooked dish.

In short the answer is that the older white Corning dishes and the Visions dishes can easily handle being placed directly from the freezer into the hot oven! That might not be a good thing for the frozen food, but the dish can handle it.

Using the newer Corningware (produced since 2000) and all Pyrex casseroles one should allow the food to thaw a bit before placing the cookware in a hot oven. That might be a good thing for the frozen food as well as the dish.

Answer 3

Yes, Corning Ware can be used for freezing.

Answer 4

it depends if it is made for oven or not. you can also look up the brand online and see if they allow it.
