Bronze is an alloy of red copper, tin and lead, and it is also the earliest alloy in the history of metal casting. Brass is an alloy made up of copper and zinc. Since zinc was discovered and used relatively late, the use of brass was also relatively late.

Produced in the late Bronze Age, the bronzes of the Han Dynasty occupy a special position in the history of bronze in China, embodying unique design ideas and characteristics, with excellent scientific functions, and have a great enlightening effect on today's design. Many of the bronzes of the Han Dynasty were plain, most of them were cast, and the inscriptions were carved with chisels.
After the Han Dynasty to the Tang Dynasty, there are many patterns of casting, including copper, gold, and silverware, and there are also large and small welding techniques. The bronzes of the Han Dynasty are exquisite and expressive. The shape is lifelike, simple and elegant, the utensils are cleverly conceived, the shape is simple and atmospheric, the casting process is realistic and delicate, and it is very collectible.
Historically, our country was one of the first countries in the world to enter the Bronze Age.

No! Bronze culture has developed in all regions of the world, because of the advantages of bronze as a raw material for tools and utensils: First of all, there is a natural pure copper block (i.e., red copper) in nature, so copper is also one of the earliest metals recognized by mankind.
However, the hardness of red copper is low, and it is not suitable for making production tools, so it plays a small role in production. Later, people discovered tin ore and learned to refine tin, and on this basis, it was recognized that copper with tin was added to it, that is, bronze, which was harder than pure copper. After measuring the hardness of red copper is 35 degrees of Brin's hard gauge, and adding 5% of tin, its hardness is increased to 68 degrees; Add tin by 10%, that is, increase to 88 degrees.
Moreover, after tempering, the hardness can be further improved. Bronze ware mainly refers to various utensils formed by firing and forging copper and tin in China from the end of the Xia Dynasty to the Qin and Han dynasties. The Chinese Bronze Age began in 2000 BC and lasted for nearly 15 centuries through the Xia, Shang, Western Zhou, Spring and Autumn periods, the Warring States period, and the Qin and Han dynasties.
It is an important part of China's culture, with important historical value and ornamental value, among which the bronzes of the Shang and Zhou dynasties are the most valuable. Bronze culture was the cultural core of the Xia, Shang and Zhou dynasties, among which the ritual vessels of the Shang and Zhou dynasties had both cultural value and high artistic value.

It is widely used in tools, weapons, wine vessels, etc., and has played a great role in production.
