Coated with mercury. The mirror's ability to reflect light was not very strong, it was time-consuming to make, and the mercury was toxic, so it was later eliminated. Now the mirror, the back is a thin layer of silver.
This layer of silver is not coated or electroplated, it is coated by a chemical "silver mirror reaction". Aqueous solution of ammonia in silver nitrate.
Add glucose.
Water and glucose reduce invisible silver ions into silver particles, deposit them on the glass to make a silver mirror, and finally paint them with a layer of lacquer. Seeing this, you will say, "The thing that shines on the back of the mirror is not mercury, it is silver."
This conclusion is behind the times again! Nowadays, there are many mirrors in the store that are aluminized on the back. Aluminum is a silvery-white shiny metal that is much cheaper than precious silver.
The manufacture of aluminum mirrors is to evaporate aluminum in a vacuum, and the aluminum vapor condenses on the glass surface to become a thin layer of aluminum film, which shines brightly. This kind of aluminum mirror is inexpensive and promising. In this way, you will say:
I can't imagine that a small mirror is also developing and changing! There are several chemicals on the back of it alone.

The reflective layer of the mirror does not contain mercury, in the past, the chemical immersion silver method of "silver mirror reaction" was used to "plate" a layer of silver film on the glass, and now there is a vacuum coating on the aluminum layer on it, saying that the mirror contains mercury, mainly after the coating in order to protect the plating from being oxidized and blackened, it was often coated with red dan lacquer before, so the mirror glass is red behind it, and the red dan lacquer contains mercury, which is no longer used now.
Mercury is not infiltrated on the surface of the glass, so it cannot be coated on the surface of the glass to form a reflective layer.

There is no mercury in the mirror, and the inside of the mirror is silver-plated!

*No mercury in the mirror**. Mercury is a metallic element, whereas a mirror is made up of glass and a reflective layer, which is usually aluminum or silver, so there is no mercury in the mirror.

Mercury is mercury, and metallic mercury is soluble in dilute nitric acid, soluble in lipids, insoluble in water. However, some mirrors are not backed by mercury, but are a very thin layer of silver plating, which is plated with a silver mirror reaction, and then a protective layer is added on top.
Silver is also soluble in dilute nitric acid. And now many mirrors have copper on their backs. Copper is also soluble in dilute nitric acid.
Mirrors on the market usually come in three different back plating: mercury, sterling silver, and copper.
So, scrub it with dilute nitric acid, nitric acid is not expensive, and it will not damage the glass (the glass is not afraid of acid, except for hydrofluoric acid), but be careful.
The removal steps should be:
As a first step, you will need to retain some protection. For example, using melted wax or other substances that can be easily removed, or a certain type of paint.
In the second step, it is invaded or smeared with erosion fluid.
In the third step, the erosion fluid is removed and the protective layer is removed. If it is a paint and does not hinder its use, it is okay not to go.

Abstract 1: There is basically no remedy for the metal behind the mirror to fall off, find a craftsman to plating it again, or buy a new one.
2. You can also try to use highly reflective materials such as tin foil to stick on the back as a substitute for mercury coating;
The mercury behind the mirror is falling off, is there any way to get it.
1. There is basically no remedy for the metal behind the mirror, find a craftsman to plating a layer on it, or buy a new one. 2. You can also try to use highly reflective materials such as tin foil to stick on the back as a substitute for mercury coating; 3. Focus on prevention, you can paint the back of the mirror to protect the others.
How to deal with mercury scratches on the back of the mirror.
There is no way to repair this, so it can only be re-plated.

What kind of cleaning agent is used for <> cleaning.
Dear, cleaning is called a bathroom cleaner.
This cleaning agent is acidic, which is why it corrodes the mercury.

The mercury mirror was invented by German scientists in 1843.
In 1843, German scientists invented silver-plated glass mirrors. The thing that shines on the back of this silver glass mirror is a thin layer of silver, which is not coated or plated, but uses a special and interesting chemical reaction. The silver mirror reaction is plated, it is in a silver nitrate solution, plus some ammonium hydroxide and sodium hydroxide, plus a little glucose solution.
Because glucose has the ability to "reduce", it can reduce the silver ions in silver nitrate into metallic silver particles, which are deposited on the glass to make a silver mirror. In order to enhance the durability of the mirror, it is usually applied to the silver layer with a red protective paint after silver plating, so that the silver layer is not easy to peel off and damage.
Extended Materials. In the 70s of the 20th century, scientists invented the aluminum mirror, which is manufactured by evaporating the aluminum in a vacuum, so that the aluminum vapor condenses on the glass surface and becomes a thin aluminum film.
This type of aluminum-plated glass mirror is cheaper, more durable, and more radiant than silver-plated glass mirrors. Modern decorative mirrors are no longer framed by wood, plastic, glass and other materials, and mirror processes such as carving, vertical line, silk screen printing, and pasting are only innovative and unconventional in modeling. This kind of mirror is mainly decorative, supplemented by "looking in the mirror".

Summary. The history of mercury mirrors can be traced back to ancient China. According to historical records, the Chinese began to use mercury to make mirrors as early as the 3rd century BC.
At that time, they coated the back of a smooth copper mirror with mercury to create a reflective surface. This mercury mirror is considered to be one of the earliest mirrors in the world. With the passage of time and technological advancements, mercury mirrors have gradually become popular and improved in China.

The mercury mirror (i.e., a mirror coated with mercury on the back) is an ancient Chinese invention that is difficult to determine. According to historical records, China has a long history of making mirrors, and the earliest mirrors can be traced back to the Warring States period in the 3rd century BC. It is said that the earliest mirror was made of bronze, and later iron and copper mirrors appeared.
And mercury-coated mirrors, known as mercury mirrors, according to archaeologists, may have appeared during the Tang Dynasty in the 7th century AD. The Tang Dynasty was known for its prosperous economy and scientific and technological advancements, and it was probably during this period that the invention of the mercury mirror was invented. Mercury mirrors enhance the reflection by applying mercury to the back of the mirror, making it clearer and brighter.
Although the exact time of the appearance of the mercury mirror is uncertain, in ancient China, the mercury mirror was widely used and continuously improved in technology, becoming one of the masterpieces of ancient technology.
The mirror reflects a plane, and there is a certain distance between the pupils of the eyes, so when you are facing the mirror, the center of the mirror is real, but the surrounding parts are distorted, but not very obvious; But when shooting in DV, it is shot with a lens, and the basic principle used is small hole imaging, which is equivalent to you only using the eyes of a mouse to see the world Note: It is one eye, so both the sense of depth and the spatial distribution are quite unreal compared to the mirror. Ha, don't worry.
Beauty lovers like to look in the mirror, which is understandable, because grooming is very important for a person's appearance, but if you belong to the category of people who look in the mirror frequently and can't tolerate your shortcomings, then you need to be careful. >>>More
Many cuties should find that every time they look in the mirror, they become more beautiful, especially when they try on clothes in the clothing store, it is more obvious, what is going on? Could it be that these are the legendary "magic mirrors"? >>>More
Because they are symmetrical, the so-called mirror effect is such a principle.
Yes, but the incense burner should be separated. Thank you.
