Antique Imari-yaki tea cups with blue and white underglaze, dating back approximately 100 years, from my parents' home. These are antique Imari-yaki (Ko-Imari) tea cups with the mark "Gorota Ho Goshuizui" on the back. * This mark indicates that the cups were made in Japan, imitating the style of Wu, a potter from the Ming Dynasty in China, and were particularly common during the Edo period. * The cups feature geometric patterns and foliage designs in blue underglaze. * Ko-Imari is a general term for porcelain fired in Arita, the birthplace of Japanese porcelain. Two cups are undamaged. Two cups have two chips on the rim (Photos 5 & 6). Size: Diameter: 9 cm Height: 4.5 cm These items are considered antiques. If you are interested, please consider purchasing them.
