Stone Age potters crafted complicated and often delicate ceramic pots, tools, and jewelry. They also crafted crude pottery figurines. Many of the delicate ceramic pots, tools, and jewelry have been found intact or nearly so, whereas the figurines, crafted at roughly the same time as the ceramics, have largely been found in tiny fragments.

C．Pottery was invented in the Stone Age, and techniques for making pottery were mastered well before those required for delicate ceramic work.
