Chemicals reactions and society development.
Bronze Age
10,000 year ago
In this average of time, people made the first tools with stone. Then, the humans started to use some metals, such as gold, silver, and copper. Nevertheless, these metals were used for decorative tools.
3,000 BCE
Humans discovered that adding Tin to the copper could make it more strong and harder and much better for making tools. The alloy of copper that we are talking about is bronze.
Advantages of Bronze
More durable tools
Was moldable
The use of bronze lead to the first swords
Iron Age
1,000 B.C
There was a spread in the production of iron objects in Europe and Asia.
Main uses of Iron
Swords
Shields
Armour
Iron with carbon
Later, early metallurgists discovered that the application of small amounts of carbon, accompanied by heat treatments, could strengthen it.
In fact, People that used these type of Iron was and advantage against people using bronze.
Roman Age
Roman Empire and Britain
When Britain came under Roman control, the lead (Eureka called at the time) became essential for the development of Britain.
It was used for roofing, building ornaments, water pipes and coffins.
Lead as a factor in the fall of the Roman Empire?
That is believed. Many historians blame on lead poisoning, since they used lead to delivered spring water and lead vessels to cook or drink.
Industrial Revolution
Coke
Coke led to the development of European societies.
Even Though environmental concerns about carbon resources, without coke, we wouldn't have a better life quality and massive economic growth.
Coke is a carbonaceous material produced from coal, in the production of Iron.
Advantages
It lowered production costs and increased production volumes.
Type of combustion.
Technology Age
Silicon chip
Silicon chip has been a very influential invention in our actual world. It scans brains, drives trains, flies planes, and it's the brain of any electronic. Only with these examples of uses, you can notice the importance of it.
Silicon chip or microchip made modern computers possible.
The ability to create a miniature circuit through a semiconductor was what gave computers vast improvements in speed and accuracy
