Gilding silverware is actually very simple.

Is to put gold in mercury, so it becomes the mud of mercury, gold and silver.

Then apply these gold and silver pastes to jewelry, wood carvings, vases, porcelain, buildings and other places where they are needed.

Then put it on the fire and bake it. After mercury vapor evaporates, gold plating is completed.

It won't wash off after electroplating.

When Eight-Nation Alliance robbed in Beijing, he cut the gilded crane and cauldron with a small knife. Even if he tore it open, he couldn't cut the gold, because it dissolved with the copper and iron below it.

10 mercuric chloride can dissolve about 3.3 liters of gold.

However, this ancient craft has done great harm to craftsmen. All craftsmen are sickly after working for 10 years, and will be completely paralyzed in a few years, and rarely live to be over 50 years old, just because of long-term inhalation of mercury vapor.
