Likely a Kyoyaki matcha bowl. Diameter: Approximately 12cm Height: Approximately 7.5cm Marked with "昌山" (Shōzan) on the bottom. There is a crack. *It's unclear whether this is a crack or a glaze crack (kannyu). There is no original box, so there is no official information. I have not studied tea ceremony and do not have appraisal skills, so please check the photos carefully before purchasing. No original box. Likely used and pre-owned. Long-term storage item. The condition is as described and shown in the photos. Will be packed and shipped via Takkyubin (courier service). It is said to have been either a gift from a relative who was a tea ceremony master or a regularly used item of my grandmother's. I am listing it because I think it would be better for someone who understands its value to cherish it. 【Search Words】 #Metalwork #Antique #Antique #OldArt #JapaneseAntique #Sencha #Crafts #TeaCeremony #TeaUtensils #Copperware #CopperProducts #Furo (tea ceremony brazier) #Kyoyaki #TeaUtensils #Sencha #Senchado (Sencha tea ceremony) #SenchaUtensils
