Revere had been producing cookware for years, and came up with their method of producing a stainless/copper combination along with a plastic (bakelite) handle during these years, but applied for the patent for it and decided to use this logo. It was stamped on the bottom of their cookware for almost 20 years. In 1968, they changed their process to use a thinner stainless steel, and also a thinner electroplated copper bottom. Copper prices, along with all metal prices were rising and it was a way to cut costs. The reduction of both stainless steel and copper continued throughout the decades. (More on that in future posts.)
Revere also changed their logo in 1968. They simply removed the double circle, the “copper clad” writing inside the circle, and the patent information below the circle, leaving the 1801, the profile, an “Revere Ware”. They continued with this logo with a few minor changes through the late 1990’s, when production within the USA shut down permanently. You can still buy Revere Ware, which is now owned by Corning, (AKA World Kitchens), but it is stamped “China” or “Indonesia”, and one variation (Pro Line) was made in Thailand for a while. The “good old pans” were and still are MUCH heavier and better than what you can buy today at Wal-Mart.
