The pulp, also known as "black lacquer ancient", is a surface skin shell gradually formed in the long years because of dust, sweat, the hands of the players, or the soil buried in the water, the long-lasting friction, and even the passage of rays in the air. It's slippery and gratifying, and the light is quiet, telling you that this thing has aged, revealing a warm old atmosphere. That's exactly the contrast with the dazzling "thief light", impetuous tone, and dry texture of the new product that has just come out.
Fake toning of real coins smells like chemical paint and is not smooth.
There are two common methods of counterfeiting:
First, the counterfeit money is calcined with fire, and after being taken out, it is cooled, and the surface of the money is black.
The second is to put the counterfeit money together with the burned wood chips, and then take it out and coat it with grease after a long time. It should be noted that the real slurry will not fall off when boiled and washed in water, so please be careful.

Thousands? The slurry is generally just to look at the rust color on it and the like.
Mother money and sample money, in general, the words are clear and powerful, and the edge of the square hole is cleaned very clean, very neat, and will be slightly larger.
If you want to be in the Northern Song Dynasty, it's best to see if there are words or patterns on the back, because the bareback of the Northern Song Dynasty is a small flat coin, and few people fake it, and the value of this thing is not high. The market price is a few cents to a few dollars, and there is no way to cheat.

First of all, the copper coins are often played in the hands of the stalls, so that they can gradually become brighter first through oil ester penetration and air oxidation. Next, the lightened coin is set aside for a period of time to allow it to oxidize on its own and slowly form a certain amount of toning. Of course, in order to further expand the aging effect, you can also put the copper coin in the shoes worn by the selling group, which also helps to improve the pulp.
Repeat the like this 3 times, and the time should be about half a year before the effect of old-fashioned, I hope it will help you.

Summary. For some items with fake slurry, boiling the slurry in boiling water will fall off, but the real slurry will not.
Hello dear, the answer to your question Is the slurry of the copper coin with slag the real slurry is:
It's true. Pulp is a professional term in the field of antique collection, it refers to the surface of the object due to a long period of oxidation and the formation of an oxide layer of the sedan car, that is, the "luster" on the bright piece, especially after the antique artifact key spring after many years, the surface of the object will form such a particularly delicate and natural luster.
For some items with fake slurry, boiling the slurry in boiling water will fall off, but the real slurry will not.

Summary. Dear kiss I'm glad to answer for you The pulp of the copper coin with slag is not the real pulp This is artificially old, the millennium or a hundred years of pulp boiling water can not be boiled off the knife can not be carved, it is the real pulp.

Dear, coins are very bright when they are just minted, whether it is ancient money or the coins we use today, after the use and circulation of their own very bright luster will slowly fade, replaced by a more gentle appearance, you can take the coins that have just been minted, and the coins of several years ago can be felt, whether the real coin is rusty or not, its pulp is layered, the transition is very natural, there is no law to follow, It is a natural fusion with the body of copper. It is difficult to do this with imitation coins, the paste of the imitation is artificially added, and a careful comparison will find that although there are some imitation of the pulp of the product, there is also a kind of old-fashionedness, but it always lacks that sense of history, the pulp is often more unified, lack of change, there is no sense of hierarchy, like a shallow floating on the surface, rather than the feeling of the real product into the bone, it seems very si, lacks that old taste, and the rust se of the blue year is not a very fake and very xie face se

Hello dear, the toning of the bronze ancient coins has a white color. Ancient coins are basically bronze or yellow slow lead copper casting, real wallet pulp generally presents blue and white, light yellow, light and noisy red and other colors, and its molecular structure is stable, tight, and not easy to erase. However, the counterfeit rust color is not, and the fake rust is mostly on the surface of the coin, which is relatively frivolous and easy to fall off.
In the natural environment, due to the contact of oxidation, acid and alkali in the air, as well as the sweat stains and dust in the hands of people, the chemical reaction with the active substances on the surface of the copper coin, coupled with the long-term precipitation and condensation on the surface of the copper coin.

1 Look at the Copper Identification Copper Coins Most of the copper coins in China were cast in the form of copper alloys, and because of the different compositions of the alloys, the copper coins also showed different colors. Generally speaking, copper coins cast with copper-zinc alloy are yellow, and copper coins cast with copper-tin alloy are cyan. Generally, pre-Qin coins were cast in bronze and were blue and white in color.
From the Han Dynasty to the Tang and Song dynasties, most of the copper coins were cast in bronze, which was characterized by a copper color of blue and white with a slight reddish tinge. After Jiajing in the Ming Dynasty, great changes began to take place in the future. Xinjiang and other places in the Qing Dynasty used red copper to cast money, and the color was purple and red.
In the process of identifying copper coins, if a copper coin is found to be inconsistent with the times, it can be concluded that it is a counterfeit.
2 Identification of copper coins by looking at rust color Improving the ability to identify counterfeit rust of copper coins is the focus of copper coin identification. Because almost every method of fraud has to be disguised with fake rust in the end. Copper is a relatively stable metal that does not rust easily at room temperature.
It takes decades, or even hundreds of years, to produce copper oxide, basic copper carbonate, etc. Patina generally refers to an oxide formed on the surface of copper coins. The length of the copper coin's minting age, the length of time of man and land, and the different geographical and geological conditions make the patina form different.
Under normal circumstances, natural rust is naturally distributed, the colors are diverse, the color is bright, and it is difficult to remove it by physical methods.
3 Look at the money to identify copper coins Many copper coins have inscriptions, which is a major feature of China's copper coins, and the coinage inscriptions of different eras have their own characteristics and different writing styles. Based on these characteristics, it is possible to test whether it is a copper coin of the same era. In addition, while paying attention to the characteristics of various money documents, we can also find out the evolution process and change law of money documents.
These rules and characteristics are an important basis for identifying the authenticity of copper coins.

Many of my friends like the original light without flowing through the condition, which is commonly known as UNC, AU and other graded coins, and I prefer the variety that flows through. The more than 100 silver coins I have collected have a different toning on the surface of each coin, which has been handed down to the world, and has endured hardships, and the years have given them a shallow toning; Or from the depths of the land, with thick green embroidery, or hidden in a remote place, once found, with colorful "flower costumes". Any item that has been washed over time will leave traces of time.
Through observations, comparisons, reflections, and many exchanges with friends in the collecting world, I have concluded that the toning of silver coins can be roughly divided into the following types:
First, the old pulp, the color is deep and mostly black, the surface of the coin is firmly wrapped, or because the part that floats on the surface is rubbed, but the adhesion between the words leaves an attachment that is difficult to remove. Typical heirlooms have an evenly rounded wear, while the black toning adorns the surface of the coin, giving the item a more aged look.
Second, the pit or can slurry, silver coins will grow like copper-like green rust, it sounds a little incredible, but the pit or canned silver coins are just in line with this characteristic, the pit is generally with heavier green rust, the pot or cellar is generally with a slight green rust, especially the pit products, a glance of green, the most conspicuous, this kind of silver coin rust color is obvious, rust and rust are also adhered to the soil, smell it is often accompanied by a strong soil fragrance, because the time of circulation is shorter than the heirloom, so most of the quality is better, and the slurry of the pit is not easy to imitate, Therefore, it is favored by spring friends, and ** climbs all the way.
3. Colorful pulp, dazzling color and beautiful image. However, the cause of its formation is the most difficult to grasp, and sometimes it is placed in a dark and damp place, and it does not take long to form. Silver coins washed with washed silver can form a shallow toning in a short time under sun exposure.
Therefore, this kind of pulp is easy to fake, for example, potassium permanganate is mixed with a certain proportion of hot water, and the silver items can be placed in it for about half an hour to form a more ideal color pulp.

I'll see you for the silver coin pulp.
What is toning? I think it should be defined as a stable, thin, uniform oxide layer on the surface of a coin. The toning must be the product of natural oxidation, otherwise it is corrosive or physical damage to the coin.
The first feature: stability. In general, the slurry does not change significantly with temperature and environmental changes and is not removed by simple cleaning (without chemicals).
Unstable oxidation phenomena can all be classified as corrosive damage, including slurry forged by various chemicals. What is easy to be removed cannot be called slurry, and some dyed or smoky, and those with dust and mud on the surface cannot be regarded as slurry.
The second major characteristic: thinness. I personally think that a very thick oxide layer is harmful rust, which is different from the slurry.
For example, some unearthed silver coins have a heavy patina that cannot be removed at all, and they may be rotten after being removed, and they will continue to develop if they are not removed. Therefore, coins with heavy oxidation should not be collected, even if they are in good condition. A good toning is one that is absent or thin and does not obscure the pattern on the surface of the coin.
The third feature: uniformity. The toning cannot be distributed on the surface of the coin, nor can it be shallow and deep. A uniform oxide layer indicates that the coin has always been in a relatively stable environment, while the oxide layer of the bantt must be caused by an unstable environment or chemical corrosion.
In addition, the original light coin is not without toning, and despite its fascinating and even dazzling brilliance, it still has a dense oxide layer on its surface, which itself protects the metal from erosion. I always believed that the glamorous glow was the result of a very flat surface without any scratches.
Good toning will make the coin more beautiful and greatly increase the collectible value of the coin. Bad oxidation corrosion and even fake pulp will make the boutique a pity, I hope that the newcomers will learn more and experience more.

The toning of the silver scarf is essentially the luster and mechanism effect of the natural oxidation of the surface of the silver coin. The surface of the silver coin interacts with the atmosphere, moisture and other substances for a long time, and rubs against each other with fabrics, ** and other substances, and the luster and mechanism effect produced by its surface are moist and natural, reflecting the beauty of the texture of the silver coin, and becoming the aesthetic connotation of the traditional silver coin, which is called pulp by the insiders. Does the toning of a silver coin matter to the condition of the coin?
A: Very important. Experienced silver coin collectors pay great attention to the toning of silver coins, not only as an important basis for identifying the authenticity of silver coins, but also as an important part of the beauty of silver coins, so they are always cautious when cleaning or removing rust from silver coins, for fear of damaging this coat of silver coins, making silver coins lose their quiet and distant interest, and damaging their aesthetic value.
What's the deal with silver coins with light? Answer: Machine-minted silver coins are demolded with butter The surface of the silver coin oxidizes under the action of butter to form a light brown or bluish layer of the original luster that can be easily destroyed, which becomes a special aesthetic in the silver coin collection, and this luster is called light.
Because this luster is so easy to protect, glossy silver coins are largely unused and therefore precious. Polished and uncirculated silver coins are considered to be in the finest condition, and are worth ten or even dozens of times more than the same type and variety without light. The text of the silver coin is arranged in a rotating and horizontal row, and what is the pronunciation?
Answer: The general order is up and down, right and left, clockwise is called right travel reading, counterclockwise is called left-handed reading. In fact, many silver coins have two different spins, usually the upper left and the lower right.
