Visions (cookware)

It will withstand heat up to 850 °C (1,560 °F) with thermal traits similar to Corning Ware plus improved resistance to staining and the detrimental effects of acids and detergents.

In 1953 S. Donald Stookey of the Corning Research and Development Division discovered Pyroceram, an opaque-white glass-ceramic material with a high thermal shock resistance.

[4] In 1977, Andre Andrieu and Serge Renault, working for Corning France, patented the claim that would form the basis for amber-tinted, transparent Vision cookware.

It was described as being a semi-crystalline ceramic having unique and useful properties such as coefficient of thermal expansion so low as to be negative in character, a true porosity of zero, and the unusual characteristic of being transparent despite a substantial crystal content (often greater than 75% by volume).

[2] Thanks to Pyroceram's extremely high thermal shock resistance, food can be stored in the freezer in a piece of Visions and immediately taken to the stovetop or oven for cooking.

When initially released in Europe, and during the Le CLAIR test marketing period in the US, many Visions products shipped with a "Cooking Lid" that was also made of Pyroceram.

These products are made of opaque Pyroceram ceramic-glass, like vintage pieces of Corning Ware, and can be used in the similar ways as Visions cookware.

Pyrex, a brand name for break-resistant glass bakeware, has offered complementary brown (Fireside) and Cranberry tinted lines to match Visions colorways in the past.

[10][11] Arc International, France, sells cookware that is equivalent to Visions under various brand names including Arcoflam, Luminarc, and Arcoroc.
