Antique Brass Identification Method, What is the Bronze Identification Method?

1. Look at the rust color.

After such a long period of time, the bronze can be handed down in three ways: passing it down, burrowing it into the ground, and falling into the water. Most of the bronzes found today are mainly unearthed, and these bronzes will be affected by copper, soil and water quality, and their rust color will also be different, the most common are:

Green, red, purple, blue rust. Therefore, after we get a bronze, we can identify it by judging the rust. Generally speaking, if the rust color can be bonded with the bronze and the shade is the same, and the appearance is smooth and natural, it is a naturally formed rust color, and vice versa, it is likely to be fake.

2. Listen to the sound.

A real bronze is not too light or too heavy in weight, depending on personal experience. Generally speaking, we can tell by the sound of striking the object, if the sound is small and brittle, it is true; On the other hand, if it makes a "buzzing" sound, it is likely to be faked.

3. Look at the pattern.

In the identification of bronzes, looking at the pattern can be said to be the most important. In general, the Xia Dynasty.

The pattern is relatively simple; Shang Dynasty.

of them are covered with patterns; Western Zhou.

In the early period, it was roughly the same as the Shang Dynasty, but in the later period, it was simple; In the Spring and Autumn Period and the Warring States Period, the pattern was more life-like, and it looked fresh and lively; In the Qin and Han dynasties.

Bronzes are less elaborate, with fewer patterns and less elaborate than their predecessors. In addition, it can be judged by the font, the number of inscriptions, and the content on the bronze. Like the well-known "Qin unified script, universal small seal, if you find a piece known as Xia Shang Zhou."

The bronzes of the period are engraved with small seals, which is funny.

The identification method of antique brass paint, so you can let the treasure connoisseur then carry out some identification based on this aspect.

The easiest way to identify brass: 1. Look at the color: Identify the copper can look at the color, pure copper is purple red, brass is light yellow, bronze is close to white, even if the surface is filed with a file.

Fake copper is generally dyed and packaged, and the surface will be exposed after being broken off with a file. 2. Listen to the sound: Identify the copper can listen to the sound, gently tap the surface of the copper, the sound of the real copper is low, it will make a "buzzing" sound, and the sound disappears slowly.

The knocking sound of the fake copper is sharp and disappears relatively quickly. 3. Use magnets: Magnets can be used to identify copper, copper is a non-magnetic substance, so when the magnet is close, it will not produce adsorption force.

Fake copper contains an iron substance that is quickly attracted when the magnet is approached.

1. The method of distinguishing the authenticity of bronze ware: fake bronze ware is cast by the wax loss method, and there is no fan line, and there will be fine sand holes, but there is no real bronze ware.

2. See if there is a gasket in the copperware.

It can also distinguish the real from the fake, and the fake bronze does not have a gasket. The shape of real bronze ware is more complex and changeable, and the weight, sound, and rust color can also distinguish the authenticity.

3. Pattern and style: This is a key point in identifying bronze ware, Xia Dynasty.

The bronze pattern is simple, and the Shang Dynasty pattern is gorgeous and complicated, and many times the body is full of flowers, the Western Zhou Dynasty.

It is roughly the same as Shang, but it tends to be simple in the later period, and the patterns of the Spring and Autumn Period and the Warring States Period are fresh and lively, full of life, Qin and Han dynasties.

Heavy and practical, with few patterns and not as fine as the previous generation.

Precautions. The storage room must be kept dry, free of dust and air pollution, relative humidity.

Preferably below 50.

Before the utensils are put into storage, all contaminated dirt must be removed, preferably chemically protected, not coated with thick grease and oil on the bronzes, and cotton gloves must be worn when touching the bronzes, and must not be touched with sweaty hands, nor can they be packaged with oily paper or boxes.

To remove the dust on the copperware, use a soft cloth, a soft brush, a soft duster, etc., and if you need to wash it with water, you must use distilled water.

Distilled water can also be warmed, neutral soap can be used, and ammonium hydroxide cannot be used.

Acids, white powder, gauze, etc., if there is a large cleaning, it can be cleaned by professionals.

The above content refers to Encyclopedia - Bronze Ware.

It can be identified from several aspects, such as rust color, feel and sound, pattern and style, copper and instrument style.

1. Rust color.

Generally speaking, most of the bronze ware that has been handed down to this day is unearthed, and there are common green rust, red rust, blue rust, purple embroidery, etc. If the rust color is integrated with the body, the depth is consistent, solid and even, smooth and natural, then it is a naturally generated rust color. If the rust color floats on the utensils, green but not shiny, the skin is rusty, and it is not moist and dazzling, it is pseudo-rust.

2. Feel and sound.

Weigh it with your hands, and if it's too light or too heavy, you need to pay attention. In addition, you can also use your hands to tap the real thing, listen to its sound, if the sound is subtle and light and crispIf the sound is muddy and makes a "buzzing" sound, you need to be vigilant.

The pattern of Xia Dynasty bronze ware is simple;The Shang Dynasty pattern is gorgeous and complicated, and many times the body is full of flowers;The Western Zhou Dynasty was roughly the same as the Shang, but tended to be simple in the later periodThe patterns of the Spring and Autumn Period and the Warring States Period are fresh and lively;The Qin and Han dynasties were practical. As for the style, it can be identified mainly from its font.

The Shang Dynasty font is regular, and the gestures are strong and generous;The early Zhou Dynasty followed the wave body;In the spring and autumn period, the body of the book has a fat body and a thin body;The Warring States period gold font is not elegant;The Qin Dynasty unified the script and used the small seal.

4. Copper and utensils.

The identification of copper is relatively simple, look at the bottom of the bronze, if the brass texture is out, it is a counterfeit;If the soles of the feet have been disguised with copper, they can be washed with hot alkaline water to see their true appearance. In addition to remembering the style and name of the bronze ware, it is also necessary to understand what era and what style of bronze was cast. For example, francium, which is square, is a container, which appeared at the end of the Warring States period;If it is made according to three generations of workmanship and rust color, it is a counterfeit.

History of Bronze Ware

China is the world's earliest civilization to master brass smelting technology, and the brass sheets and brass rings unearthed from the Jiangzhai site are smelted, 6,700 years ago. China's bronze smelting is also earlier, the earliest smelting bronze in China is the bronze knife unearthed from the Majiayao site in Gansu, which is 5,000 years old.

Heyday: late Shang Dynasty, early Western Zhou Dynasty, 13th century BC - 11th century BC. From the late Shang Dynasty to the early Western Zhou Dynasty, bronze art was brilliant.

Whether brass antiques are worth anything needs to be judged from multiple angles.

In terms of collectible value, generally speaking, brass is not collectible. Brass is a common alloy that is made up of copper and zinc. Because of its high stability, corrosion resistance, easy processing and other characteristics, it is widely used in construction, decoration and other fields.

Among the brass products, some products with special historical background and exquisite craftsmanship, such as copper mirrors, copper kettles, copper bells, etc., have certain collection value.

However, not all brass products are collectible. Some common brass products, such as ordinary copper locks, copper faucets, etc., do not have too high collection value due to their large output and relatively simple process.

In addition, whether brass antiques are worth also needs to consider factors such as the age, craftsmanship, and preservation of antiques. If a brass antique has a high historical value and is characterized by exquisite craftsmanship, then its value may be even higher.
