Fragments double age of human pottery

Pottery fragments found in a south China cave have been confirmed to be 20,000 years old… oldest known… Earlier theories have held that the invention of pottery happened during the period about 10,000 years ago when humans moved from being hunter-gathers to farmers. … These pots push the invention of pottery back to the last ice age… [Perhaps agriculture arose earlier, or even on and off throughout ten thousand years of change, rather than just at the 10K-years-ago threshhold? H/t again to commenter "FizViz, Brighton UK," whose use of the term "Urantia" brought this to my attention.]
