A silversmith doesn't need to drill wood for fire. Goldsmiths, also known as silversmiths or jewelers, have a history of more than 3,000 years in China. The silversmith's tools mainly include hammers, scissors, files, saws, molds, special furnaces and fire blowing tools. In the process of operation, the goldsmith squatted in front of a small stove only knee high, and constantly sprayed fire on the gold and silver with a fire-breathing thin tube to melt it. The molten liquid was poured into the mold, cooled and shaped, and then carefully polished, and a beautiful work was completed.
