I saw a "wide pot" in a book about Ming history. What kind of pot is this? Do you still use it now?

The book that the landlord said should be a biography. In the fourth year of Qin Long, Tatars paid tribute to the Ming Dynasty and traded with each other. Zhang and Wang Chonggu have been contemplating four things. The second thing is that "the Tatar client bought a pot made of iron, which will be the source of weapons in the future and cannot be easily sold. The wide pot can't be used for casting weapons, so it's better to sell it, but when you buy it, you have to change it to a broken iron pot. "

According to historical records, during the Ming and Qing Dynasties, Foshan was once the production place of custom-made iron pots for the royal family, and "Foshan casting" was also called "red mold casting". More than 80% of the iron pots exported by foreign merchant ships from Guangzhou are "Foshan casting", so Foshan iron pot is also known as "wide pot". The iron pot cast by "red mold casting method" is extremely thin, only 2 mm.

The Ming Dynasty didn't sell iron pots to Mongolia for fear that the Mongols would cast them back to make weapons and armor. Later, for various reasons, it was resold to Mongols and also sold to their crude pots, commonly known as Luo Guo. (For example, the 10 kg wide pot sold before can make 5 kg of iron, and the Luo pot can only make 3 kg. But according to modern research, it may be that the Ming Dynasty really thought too much. Because, as mentioned at the beginning, the handicraft level of Mongols at that time was actually quite degraded. It was not until the Ming Dynasty that it was discovered that some Mongols would try their best to rob them, but the iron pots that could not be mended were not returned to the furnace, but thrown away. On the contrary, Japanese and Southeast Asians actually import Foshan iron pots (wide pots) to strike iron.
