Is gilt bad for the body, and is gilt ware poisonous?

Dissolve in mercury as a paste of gold amalgam, evenly coated with gold amalgam on the surface of clean metal utensils, heated to volatilize the mercury, and consolidate with the metal surface to form a bright golden yellow coating, which is called fire gold plating.

Steps. 1.Anointed with nitric acid.

The aqueous solution will then be brushed on the surface of the plated parts to remove impurities and dirt, so that the gold mud and the surface of the plated parts are easy to bond and adhere tightly. With a special flat head.

The copper stick is commonly known as the "gold stick", or the gold mud is evenly smeared on the plated surface with a brown brush, while wiping, pushing, and pressing, this pushing technique is called "tethering", three points of wiping, seven points of leashing" shows that "leashing" is an important part of the fire gold plating process, and it is the key to the technology of dense organization and tight combination of the margin layer.

2.Baking: According to the shape and size of the plated vessel, various forms of charcoal furnaces are built, and there are air blast and exhaust devices.

to ensure the heat and the elimination of mercury vapor. The plated parts are smeared with gold clay and baked on a charcoal fire, and at the same time, the surface of the layer is continuously pressed, and with the gradual evaporation of mercury, the surface color of the gold layer changes from silver-white to golden-yellow. This process of baking and changing color is commonly known as "opening gold".

3.Cleaning: After opening the gold plating parts, then use sour plum.

water, dried apricots. Weak acids such as water.

Clean the surface separately, and then, brush with a copper brush dipped in soap water to make the surface bright.

4.Color finding: After the gold is opened, the thickness of the gold plastering may not be completely uniform due to the different heat conditions of each furnace.

As a result, the parts of the plated parts will have inconsistencies such as light yellow and dark yellow. When all the parts of the fire gilding utensils are plated, they are put together to compare the difference in gold, and a standard color is selected from them, and the others are subject to this, and then the gold clay is partially smeared and baked, so that the whole is one color.

5.Grinding: Use agate pressure or steel pressure to grind along the surface of fire gold plating in order to make the gold layer dense and firmly combined, and the surface presents a very bright fire gold plating layer. This step can also be made by pressing the above process several times and then pressing it once.

The simulated pyro-gold plated copper sheet is 36 microns thick after four iterations of the above process. The number of repetitions of fire gold plating should be repeated three times according to the requirements of the physical object, and more than seven times, so as to obtain the bright gloss of the surface of the gold layer, the dense and pure structure of the gold layer, and the tight and porous joint between the gold layer and the surface of the matrix.

It is harmful to the body, there are certain toxins, whether it is eaten in the stomach or sucked in the lungs, it may cause cancer.

Gilt is the combination of gold and mercury.

Synthetic gold amalgamation is applied to the surface of the bronze vessel, and then heated to evaporate the mercury, and the gold adheres to the surface of the vessel. The record of gold mercury was first found in the "Zhou Yi Shen Tong Deed" by the Eastern Han alchemist Wei Boyang

The earliest record of gilding technology was seen in the Liang Dynasty. "Compendium of Materia Medica: Mercury Bars" quoted Tao Hongjing of the Liang Dynasty as saying: Mercury "can digest gold and silver to make mud, and people use plating."

Depending on the process and composition, it is definitely harmful to health - mercury!

Generally not toxic.

Gilding is toxic during operation, and some harmful substances will be added to gilding during the production process, so heavy metal poisoning is easy to occur at this time. However, after the gilt is made, most of the toxic substances in it are volatilized, so people wear or use gilt jewelry, which will not cause any harm to the human body.

With the rapid development of modern science and technology, people have already improved the gilding process and improved the safety performance of its operation, so people can rest assured that they can boldly use the jewelry related to gilding, which will not cause harm to people.

Hello! The pro-gilt cup is not poisonous. The so-called gilding, refers to the method of applying gold mercury to plating gold, the gold and mercury synthesized gold mercury, coated on the surface of the copper, and then heated to evaporate the mercury, the gold is attached to the surface of the vessel, and gilding has certain disadvantages in ancient times, but now, the gilding process has long been changed, improving the safety performance of its operation, will not produce harm.

Gilding is a traditional metal processing technology, China is the first country in the world to use gilding technology, according to the relevant unearthed cultural relics to confirm, China's gilding technology began in the Warring States period. Gilding is also known as "fire gold plating" because of the processing method and process principle, this process uses ** and mercury as raw materials, and its production is divided into five steps: gilding, baking, cleaning, color finding, and brightening.

The tea set used for drinking tea is best made of all ceramics or glass, and the gilded one is because there is a metal material in it, and through heating, it will release toxic substances, so it is not recommended to use it.

Gilding is one of the decorative techniques of ancient metal crafts. The method of applying gold amalgam is gilded, which is called "fire plating" in modern times.

This technique has appeared in the Spring and Autumn Period and the Warring States Period. In the Han Dynasty, it was called "Jin Tu" or "Huang Tu".

Gilding is a kind of metal processing technology, also known as "gold coating", "gold plating", "degree gold", "flowing gold", is a gold mercury synthesized from gold and mercury, coated on the surface of copper, heated to evaporate mercury, so that the gold is firmly attached to the surface of copper without falling off.

The so-called "silver gilding" means that silver utensils are decorated with gilding.

One of the gilded ancient metal craft decoration techniques. In modern times, it is called "fire gilding". This technique has appeared in the Spring and Autumn Period and the Warring States Period.

In the Han Dynasty, it was called "Jin Tu" or "Huang Tu". Gilding is to synthesize gold and mercury into gold amalgamation, apply it to the surface of copper, and then heat it to evaporate the mercury, and the gold is attached to the surface of the vessel. The record of gold amalgam was first found in the "Zhou Yi Shen Tong Deed" by the Eastern Han alchemist Wei Boyang.

The earliest record of gilding technology was seen in the Liang Dynasty. "Compendium of Materia Medica: Mercury Bars" quoted Tao Hongjing of the Liang Dynasty as saying: Mercury "can digest gold and silver to make mud, and people use plating."

This account is about eight centuries later than the appearance of gilded objects. The gilding method can be broadly divided into five processes. (1) Imitation of "golden sticks".

Prepare a copper stick, flatten the front end, warp it slightly, dip it in mercury, and dry it to become a "golden stick". (2) Bad gold. That is, dissolve**, dissolve with mercury.

After the gold is dissolved, it is poured into a basin of cold water to make it a thick mud, which is called "gold mud". (3) Anointing. That is, to apply gold clay to the utensils.

4) Open gold. Put the red-hot smokeless charcoal in a flat wire cage, pick it up with a metal stick, and roast it around the place where the gold is plastered to evaporate the mercury in the gold clay and make it close to the surface of the utensil. (5) Calendering.

Presses made of agate or jade with a hardness of seven or eight degrees are repeatedly ground on the gilded surface to flatten the gilt for reinforcement and brightening. The No. 1 tomb sacrificial pit of Guwei Village, Huixian County, Henan Province, unearthed a piece of Huang, made of seven pieces of jade and two gilded bronze beasts, is the earliest gilded artifact that has been discovered.

Gilding is a traditional process created by the ancient working people in the production of labor.

It is to synthesize gold and mercury into gold amalgamation, apply it to the surface of the bronze vessel, and then heat it to evaporate the mercury, and the gold adheres to the surface of the vessel.

This technique has appeared in the Spring and Autumn Period and the Warring States Period. In the Han Dynasty, it was called "Jin Tu" or "Huang Tu".

The method of applying gold amalgam is gilded, which is called "fire plating" in modern times.
