Vintage & Process Patent

Must Know’s for Revere Buyers

All Old Revere Ware is not “Vintage” Revere

The copper cladding on Revere Ware distributes cooking heat preventing hot spots, which cause food to burn and stick. The older, “Vintage” Revere Ware (before 1968) was made using an electroplating process that resulted in a thick, heavy layer of cladding giving it the legendary “Revere Ware” cooking qualities. Starting in 1968, Revere economized their manufacturing process, and reduced the thickness of the copper cladding by almost 50%. Invisible to the naked eye, this change not only lowered costs but also reduced the effectiveness of the cladding to such a degree that the cooking qualities were adversly affected.

The Revere Ware available new today may look like Grandma’s – but it doesn’t cook like it!

Process Patent

Used Revere Ware is often labeled “vintage” because it looks old, rather than because it has the original, thick cladding – Since the difference isn’t visible, how does a buyer know which is which? Simple, look for the “Process Patent” hallmark. All Revere Ware made with the original, thick copper bottom was imprinted with the logo – (“18 – Revere’s Profile – 01” over “Revere Ware” inside a circle), AND carries the inscription: “Pat.Pend.” (prior to 1941), or “Made Under Process Patent”(1946-1968). Newer Revere Ware (made after 1968) has a much simpler logo, or has no note regarding “patents”

So, to get the original “vintage” Revere Ware (the kind your Grandmother loved), just look for that “Process Patent” hallmark.
