About ironing

No-one can say exactly when people started trying to press cloth smooth, but we know that the Chinese were using hot metal for ironing before anyone else. Pans filled with hot coals were pressed over stretched cloth as illustrated in the drawing to the right. A thousand years ago this method was already well-established.

Meanwhile people in Northern Europe were using stones, glass and wood for smoothing. These continued in use for "ironing" in some places into the mid-19th century, long after Western blacksmiths started to forge smoothing irons in the late Middle Ages.

If you make the base of your iron into a container you can put glowing coals inside it and keep it hot a bit longer. This is a charcoal iron, and the photograph (right) shows one being used in India, where it's not unusual to have your ironing done by a "press wallah" at a stall with a brazier nearby. Notice the hinged lid and the air holes to allow the charcoal to keep smouldering. These are sometimes called ironing boxes, or charcoal box irons, and may come with their own stand.

Late 19th century iron designs experimented with heat-retaining fillings. Designs of this period became more and more ingenious and complicated, with reversible bases, gas jets and other innovations. By 1900 there were electric irons in use on both sides of the Atlantic.
