According to the national regulations, only the national standard 1 gold bricks and finished gold bars can be marked with 9999. Gold ornaments can only be marked with K gold. Tiger balm is not recognized by the national standard, but a gimmick for businesses to make money.

Gold plating: one of the decorative techniques of ancient metal crafts. Gold plating with gold amalgam is called "fire gold plating" in modern times.

This technology appeared in the Spring and Autumn Period and the Warring States Period. Han dynasty called it "golden painting" or "yellow painting".

Gold plating is to synthesize gold amalgam from gold and mercury, coat it on the surface of bronze ware, and then heat it to evaporate mercury, so that gold will adhere to the surface of the ware. The record of gold amalgam was first seen in the Book of Changes, written by alchemist Wei Boyang in the Eastern Han Dynasty. The record of gold plating technology was first seen in the Liang Dynasty. "Compendium of Materia Medica Mercury Bar" quoted Tao Hongjing as saying: Mercury "can digest gold and silver and make it into mud, and people are also plating things." This record is about eight centuries later than the appearance of gold-plated objects.

The ancient method of gilding can be roughly divided into five processes.

(a) imitation "golden hoop". Prepare a copper rod, flatten the front end, tilt it slightly, dye it with mercury, and dry it to become a "gold rod".

(2) gold. Soluble gold, soluble mercury. After gold is dissolved, it is poured into a cold water basin to make it sticky and turbid, which is called "golden mud"

(3) gilding, that is, smearing gold mud on the vessel.

(4) open gold. Put the red-hot smokeless charcoal into a deformed wire cage, pick it out with a metal rod, and bake it around the place where the gold is smeared, so that the mercury in the gold mud evaporates and the gold sticks to the surface of the object.

(5) Calendering. A press made of agate or jade with hardness of seven or eight degrees is repeatedly polished and pressed on the gold-plated surface to flatten the gold-plated surface, which plays a role in strengthening and brightening.

A piece of yellow unearthed from No.1 curtain sacrificial pit in Guwei Village, Huixian County, Henan Province, consists of seven jade articles and two gold-plated bronze beasts, which is the earliest gold-plated object found so far.

In ancient times, gold plating was used not only for the surface of objects, but also for weapons. (For example, Yuwen Chengdou in the Sui and Tang Dynasties was plated with phoenix wings)
