2 Vintage Iroquois Cooking or Burner Pads

Two Vintage Iroquois China Cooking or Burner Pads . Pads were made to go between stove top burners and Iroquois cookware. The pad states "Use me with your Iroquois China for more effective "cookmanship". Place me between burner and your Iroquois Fry Pan, Sauce Pan or Dutch Oven (they are specifically designed for top-of-the-stove use). I'll keep foods from sticking or burning, eliminate smoke stains, spread heat evenly. For best results, heat and cool slowly, never heat when empty, don't place hot utensil on cold surface. Happy cookmanship with Iroquois." Good condition, one shows evidence of heat. Insurance is optional, however, I will not be responsible for loss or breakage if not purchased. Will combine shipping on additional purchases of my items. Thanks for looking.
