英文說明:Irons have been in common use since antiquity. This two-piece boat-shaped iron is made of iron and equipped with a chimney-shaped ventilation hole. It has a lid on top, a large casing, and a ventilation hole which could be fanned to increase the temperature of the iron, thereby lengthening the time that the iron could be used. Irons of this sort were later replaced by electric and steam irons.
