'Potter's' in the Bible

Surely your turning of things upside down shall be esteemed as the potter's clay: for shall the work say of him that made it, He made me not? or shall the thing framed say of him that framed it, He had no understanding?

Its collapse will be like the shatteringof a potter’s jar, crushed to pieces,so that not even a fragment of potterywill be found among its shattered remains—no fragment large enough to take fire from a hearthor scoop water from a cistern.”
