The ancients put red-hot charcoal into the iron, and then used it to iron clothes when the bottom of the iron was hot. This is the same as the high-temperature principle of modern irons. Therefore, the ancient iron is also called "fire bucket". There is also a kind of iron called "Golden Bucket", which is a very delicate iron, but it is not affordable for ordinary households. This kind of SW-101 1100W-1600W Electric steam iron generally only appears in the royal family.
Later, because irons also had scales, those inaccurate scales were expressed as rulers, which meant that they could measure the world. They were a kind of scepter, and they also meant that the future was magnanimous, and they were placed on desks for auspicious colors.
The original iron was made by using rocks, pottery pieces or copper iron blocks to heat them on the fire, and then pressing them on the clothes for ironing. According to legend, the iron was first invented at the end of the Shang Dynasty. According to the "Huainan King", "Branding began with a bucket." The book also noted: "Bowls, irons. King Zhou saw that the irons were rotten, so he was tortured for branding." That is to say, the inspiration for the penalties of artillery-burning invented by King Shang Zhou came from the iron. King Shang-Zhou saw that when irons were used, the iron burned a person’s hands, so he invented the "torture of artillery and bronzing"-burning people on a hot copper pillar .
However, the earliest irons seen in physical objects were from the Western Han Dynasty. Irons are often unearthed in Han tombs. Most of the irons of the Han Dynasty were cast in bronze, with a round belly and wide mouth, with long handles and some long handle ends. Also decorated with dragon patterns. There is a Western Han copper iron in the collection of the Cultural Management Office of Hanjiang District, Yangzhou City. It has a total length of 31.2, a handle length of 14.8, a diameter of 17.9, and a depth of 5.6 cm. It was unearthed in 1985 from the Xinmang Tomb of Baonudun, Yangshou Township. It has a round body, flat bottom and wide mouth. The edge has a long straight shank and the shank is decorated with a dragon head. Before ironing, put the burning charcoal in the iron, and use the heat transfer and weight of the metal to iron out the wrinkles on the clothes or iron out the beautiful wrinkles.
