A mystery of the mountains

This is a decorative bluish clay jar with inlaid dark blue slip lines. These lines outline mountain ranges. The worn, polished and opaque finish resembles water-polished stones. Inside it has a glossy dark blue glaze. It has very thin and delicate walls, though the shape is strong. It is modelled by hand, with pinch and Lulo techniques, worn and polished continuously, until its final appearance is achieved.
