text_A: Pottery making began in the 7th millennium BC. The earliest forms, which were found at the Hassuna site, were hand formed from slabs, decorated-and-glazed, low-fired pots made from reddish-brown clays. Within the next millennium, wares were decorated with elaborate painted designs and natural forms, incising and burnished.
text_B: Given what we know about pottery making in the 7th millenium B.C. if archeologists found evidence from the same time period that showed mixing of ash and sand, or similar compounds, would the reasonable assumption be that such mixtures had another purpose, unrelated to pottery making?
NO.
