This vintage Warm-O-Tray does NOT hold a temperature that is hot enough to safely keep food. However, it would be a fabulous little device for creating small melted crayon art pictures. The size is perfect for making Valentines or "stained glass" window hangings or whatever else you may imagine. Again, this is NOT being offered as A FOOD WARMING APPLIANCE. It's offered as an older tool to be repurposed artwork or...? It's clean and functional and tested to heat a small pan of water to up to around 100°F.
