The first step is to build the furnace (floating furnace and submerged furnace; the structure of the furnace includes the furnace body, a lid - cyclone, and an annular iron ring - rotating; the raw materials for making the furnace are pond mud and rice husks). Next is the product creation process including shaping to create a product model; creating molds to cast into bronze; preparing, cooking and pouring copper; engraving and arranging patterns on the surface of the product; polishing and coloring the product. When smelting copper, combine the appropriate ratio of copper, zinc, and a very small amount of lead; molding: creating a mold according to the shape of the item to be manufactured; inlaid: create an additional round inlaid sheet, hammer the product with a specialized hammer (awl - inlaid awl, mounding awl, barrier awl, parasol awl, patting awl), touch with a tick (brake tick, cupped tick, sharp tick), round, circle, pat the gums, roast, flatten, and cure.
