Any insight as to the country of origin and century these might have been made? There of red clay it seems, large one is about size of basketball with shiny glaze on interior, when light is reflected inside the jars it seems like gold flakes that shimmer back. These along with others were recovered in very deep waters in Visayas, Philippines. Can anyone steer me in the right direction are they rare? What might they be worth. Thanks in advance
