Umbrella

Umbrellas were invented by the Chinese. The umbrellas were made from oiled paper because oil repels water. The frames of the umbrellas were made from mulberry bark or bamboo. Red and yellow umbrellas were used by royalty, and blue umbrellas were used by the common people. The Chinese also used umbrellas to keep the sun off their skin.

 

Seismograph

Inside the vase swung a long metal pendulum. Outside the vase, eight dragons' heads were mounted onto its sides. The dragon heads were evenly spaced apart and each dragon had a ball in its mouth.

Remember that during the time period of ancient China there were no methods of fast communication available; therefore, it was important to have a clue where to head with the supplies.

Blast Furnace

In the 6th century B.C. , the ancient Chinese were the first people to use cast iron for tools, weapons, and cooking pots. It was a long process to make the cast iron. Therefore, in the first century A.D. , a blast furnace was invented by an unknown person. The blast furnace was powered by steam and boiling water. The furnace shot out hot air which heated the iron. Heated iron is much easier to work with. This early furnace might have opened the way for the creation of steel.

Tea Shredder 

The ancient Chinese loved to drink tea. Drinking tea became very popular during the Tang Dynasty. At first, tea leaves had to be chopped or shredded by hand which was very time-consuming. A Chinese inventor created the tea shredder. The tea shredder had a wheel in the center which would slice the tea leaves into thin ...
