Hello Min, I’m very glad that you chose Mearto for your online appraisal, Considering the photographs, overall pattern, porcelain quality and the colours, I concluded that this is an Entirely Hand Made and Painted Longnecked Celadon Bottle. The piece was mainly used for water and several alcoholic beverages traditionally. The neck of the piece resembles a standing tube originated in the Chinese celadon of Yuezhou Kiln. Such examples are also witnessed in Goryeo suncheongja. The neck has cloud designs. An Meander patterned band encloses its shoulder, and peony and chrysanthemum blossoms take turns decorating its body. The piece is almost an identical copy to a Goryeo Dynasty Celadon piece which is now in the National Museum of Korea. The piece is made by the porcelain artist Chul Ju Bang. The neck is faceted in the original piece and the Meander pattern is not used on the rim. The piece has a certificate of authenticity-introduction.The piece dates back to the period from 1965 to 1980. The piece is in good condition without visible problems. Entirely hand painted. Dimensions: 10.5 Inches Tall Condition: The piece is in good condition without visible problems. Provenance: Inherited from a friend. Heavily decorated by traditional Tabriz patterns. 150-300$.
