Archeologists find ancient kilns in Greece

ATHENS, Greece, Oct. 20 (UPI) -- Archeologists have found clay fireplaces in southern Greece that could be a historical bridge between kilns and much older stone hearths.

European and Israeli scientists, in a study summarized in the latest edition of the journal Antiquity, unearthed more than 70 clay fireplaces at Klisoura Cave 1 in Greece's Peloponnese in ground layers associated with a prehistoric culture known as the Aurignacian.

The structures bridge the gap between kilns, used for cooking between 34,000 and 23,000 years ago, and more ancient stone hearths of the Middle Paleolithic age.
