Enamel is a composite material that solidly combines inorganic glassy materials with the base metal by melting and solidifying them. Enamel originated from glass decorative metal. Ancient Egypt emerged first, followed by Greece. In the 6th century, European inlaid enamel, patterned enamel, relief enamel, transparent enamel, and painted enamel were successively introduced. In the 8th century, China began to develop enamel, and by the end of the 14th century, the enamel technique was becoming increasingly mature. In the mid-19th century, the products produced during the Jingtai period of the Ming Dynasty were particularly famous, hence the name "Jingtai Blue". In the early 19th century, Europe developed cast iron enamel, laying the foundation for the transition of enamel from handicrafts to daily necessities. However, due to the backward casting technology at that time, the application of cast iron enamel was limited. In the mid-19th century, the development of various industries led to the rise of steel plate enamel and ushered in a new era of modern enamel. From the late 19th century to the first half of the 20th century, the emergence of various types of enamel with different performance, the promotion and application of steel plates and other metal materials, and the continuous updates of refractory materials, kilns, and coating technologies accelerated the development of the enamel industry
