Original Patent Model of Mrs. Potts Sad Iron Patented 1871 by Mary Potts This patent model shows that the body of the iron was cast hollow and was later filled with material that was a non-conductor of heat, such as plaster of Paris, cement or clay. Mrs. Potts claimed in her patent that this material held the heat longer so that more garments could be ironed without reheating the iron. Mary Potts received a series of patents for variations on her iron. Some patents also were reissued.
