The potter’s wheel is believed to have been invented in Mesopotamia around 3500 B.C.

Even so, a great deal of practical knowledge was ascertained as properties of metals were observed and processes such as glassmaking and alloy production were figured out. People believed that natural processes were caused by spirits. In ancient times people, sciences such as chemistry, biology and physics did not exist. The word chemistry is derived from the word Alchemy which is the ancient name for Egypt. Ancient Egyptian plane? The Egyptians developed fairly sophisticated chemistry through cosmetic-making, dying, glassmaking and gold metallurgy.
