A small size double pointed sad iron with a detachable Walnut handle. This iron has a cast iron body with a cast iron top section.. It may have been used to iron lace or smaller type items. Very nice condition. In the 1870's, Mary Florence Potts of Ottumwa, Iowa patented an iron with a sad iron with a detachable handle, thus allowing the iron to be heated without also heating the handle. Excellent condition The sad iron — whose name derives from the Old English word “sald,” meaning solid — first appeared in the 17th century. The basic sad iron is a shaped piece of metal, with a polished base and attached metal handle. These irons were heated in front of an open fire or on a stove. The undesirable aspect of this, however, was that it heated the handle as well, so they had to be held with a potholder or thick glove.
