What did the Neolithics use pottery for?

Answer 1

The neolithics mainly used pottery for food and water storage. The clay was dense enough after firing, that it provided protection from insects. Water was also stored in clay vessels. The clay was porous enough to allow a bit of surface leakage, that would cool in the wind; consequently, keeping the water stored inside the vessel cool.

Clay was also used for decorative items, spiritual tokens and amulets, and adornment for the body.
