The art-deco style Revere Ware tea kettle stainless steel body, copper bottom, and Bakelite handles is an iconic part of the Revere Ware line and has been around since the early days of Revere Ware; vintage revere ware tea kettles
earliest evidence we have is from an ad from that shows the tea kettle as part of the Revere Ware vintage revere ware tea kettles.
Revere Ware aka World Kitchen still produces tea kettles that are much the same as they were back in the vintage days. The main difference is appears to be the thickness of material used. Because most people leave their kettles on the stove, it is very common for them to pick up grease splatter from everyday cooking. The grease gets cooked on as you repeatedly heat the kettle and can be hard to get off. The first thing to try is Bar Keepers Friend, which is very good at removing baked on grease.
