The process for making these items came from China.

by the second century A.D.
They probably first used the

Making paper was considered a fine art, and the

secrets to making it were highly guarded.

When the Chinese lost a battle to the Arabic army in 751 AD, skilled papermakers began making paper in Samarkan. Papermaking spread across the Arabic Empire to places like Syria, Egypt, and Morocco.

rocks quartz and feldspar with clay. After being baked

at a very high temperature, the pottery becomes hard, white, and waterproof.
The Chinese were making porcelain by the 10th Century, and became famous for their dishes.
We still often call fine dinnerware “china.”

stronger.
They learned that by melting different types of iron

and adding air, a chemical reaction is caused, making steel.
Steel is made from iron, but it is less brittle (breakable) than iron and easier to bend into different shapes (flexible).
