First, the number of enamels is small. Because it is difficult and expensive to make enamel, it often takes three to four months to make an enamel bottle, so it is rarely handed down. At present, there are more than 400 pieces of nearly 200 varieties of Qing Palace enamel porcelain in the world.
Second, no two enamels are the same. When the flat tire entered the palace, the court painter chose the painting pattern, so each piece of enamel was painted separately. This kind of enamel is called ancient porcelain. However, none of the enamels handed down from ancient times have this style, and ancient times have become synonymous with the noble status of enamel.
