Where are the starting points for processing bone, metals, and clay?

Work on clay began long ago around the 15th century BC, in the states: China and Ancient Egypt. It was from clay that all things were made at that time, and they were the simplest. For example, a clay cup from that period is completely different from the dishes of our days.
