"We have found four tiers to the kiln and there may be even more," Arif Mammadov, head of the Ganja archaeological expedition, told 1news.az.
"Archaeological digs need to continue if we are to find more. I would like to stress that this is the largest kiln found in Azerbaijani territory," Mammadov said.
Archaeologists from the National Academy of Sciences' Institute of Archaeology and Ethnography and the Ganja Regional Scientific Centre resumed excavations in and around Ganja on 1 to 5 March.
The expedition also found the ruins of a medieval town and cemetery during digs in Ganja.
