Bronze was a combination of to common materials, copper, tin, and rarely partly made of silver. Bronze was used for making many different things like war-chariots, bronze tipped weapons and tools, like spears and hoes, containers, and other bronze accessories. The Chinese made these items by melting it and putting them into molds of whatever they were making. Bronze was highly valued during the rule of the Shang dynasty, but as time went on it became less and less valued. Bronze is still used today, but for people who use it a lot can get skin diseases due to chemicals in the mixture of materials.
