Aceramic is defined as "not producing pottery". In archaeology, the term means "without pottery". Aceramic societies usually used bark, basketry, gourds and leather for containers.[1]
"Aceramic" is used to describe a culture at any time prior to its development of pottery as well as cultures that lack pottery altogether. A preceramic period is traditionally regarded as occurring in the early stage of the Neolithic period of a culture, but recent findings in Japan and China have pushed the origin of ceramic technology there well back into the Paleolithic era.
