In the early years of the Corning smooth top range, Frigidaire made the oven part of the range. The Corning smooth top was much better than many who tried to copy the look, except for the way the white surface stained. All 4 elements were thermostatic and the heating elements under the ceramic were ribbon elements so that the heat was very even under a pan. Major disadvantage was that large pressure cookers and water bath canners could not be used because the thermostat would cut the current before the large pan was hot enough. So Corning came out with the 3 + 1 range that had 1 non-thermostatic element. This was around the time in the 70s when people were going back to canning.
Has anyone see the Corning Cook Mates-shaped aluminum cookware for these ranges? I believe it was made by Northland Aluminum, the company that produced Bundt pans because they sold some of the stuff under their own label. The Northland pans were white on the outside and white Teflon on the inside. It sat really flat on the Corning range because the base was precision ground to be flat. The pans had wide ears like the redesigned Corning pans of the early 70s, used the newer style Corning covers (A-7) and the wide clamp, new handle. The Teflon was not a success. Even mine peeled and I never used metal utensils. If you ever spot a deep kettle that looks like a tall Corning Dutch Oven in a thrift store or at an estate sale, that is one of the 8 qt aluminum pans for the Corning cook top. Can you imagine how much that would weigh if it were made from pyroceram? The Corning compatable aluminum pieces sold by Corning range dealers either had white or beige experiors and gray non-stick (or "no stickum" as Julia Child would say) interiors.
