There were no iron pots before the Song Dynasty, so how did the ancients cook?

There was no "shallow frying pan" before the Song Dynasty, which means that the shape of the whole pan changed greatly. The "shallow bottom" increases the fire surface of the pot. At the same time, the thickness of the casting is also reduced, which makes the heat conduction better, thus realizing "fire explosion". After the Song Dynasty, cooking became popular on a large scale. Before that, it could only be achieved by cooking and other methods. The wok has nothing to do with "cooking" or "cooking". In fact, the cookers used by the ancients included bronzes (rare), pottery and iron.

The latest appearance of iron in archaeological research was in the Spring and Autumn Period and the Warring States Period. Iron is extremely precious because its initial output is very low. Until the Han Dynasty, iron was directly controlled by the state, so it was impossible to popularize iron pots on a large scale. However, according to archaeological findings, although the iron pot in the Han Dynasty was unearthed, its shape was similar to that of a cauldron, and it was far from the modern iron pot. However, these luxuries belong to the aristocratic class, so the royal family can enjoy them.

Around 1 100, Europe learned cast iron technology. In Europe in the late Middle Ages, there was a cast iron pot, which was often regarded as a treasure and passed on to future generations through wills. /kloc-Europe in the 4th century was equivalent to the Yuan Dynasty in China. Most iron pots are big pots with three legs at the bottom. At that time, the manufacturing cost of cast iron crucible in Europe was very high, and the crucible wall was very thick, which was caused by the immature cast iron technology.

China's pottery-making technology is quite advanced. For example, during the Northern Song Dynasty, there were five official kilns in China. For example, at that time, some household appliances used by ordinary people were still very cheap, so more ordinary people used clay pots to cook. Later, ceramic technology became more and more mature, and pottery pots became porcelain pots. Even today, we still use porcelain bowls.
