Iranian archeologists have found the remains of an ancient kiln in the country's southern Fars Province, which they say dates back to some 4,700 years ago.
“The third phase of archeological excavations at Mianroud Mound yielded part of the 1.30-meter-tall fireplace of the circular kiln,” IRIB quoted head of the archeology team Mousa Zare as saying. (Source)
