This appears to be a Kusayama Tenmoku tea bowl, but details are unknown. Diameter: Approximately 12cm Height: Approximately 7cm There is a mark of "Kusayama" on the bottom. Compared to other tea bowls, it is very light. The rim of the tea bowl has a step. It is unclear whether this is normal. There are some areas that appear to be damaged or stained. Please check the photos. There is no original box, so there is no official information. I have not studied tea ceremony and have no appraisal skills, so please check the photos carefully before making a purchase. No original box. It is believed to be a used, second-hand item. It has been stored for a long time. The condition is as described and as shown in the photos. It will be packed and shipped via Takkyubin (home delivery service). It was either a gift from a relative who was a tea ceremony instructor or a regular item used by my grandmother. I am listing it because I think it would be better for someone who understands its value to take good care of it. 【Search Words】 #Metalwork #Antique #Antiques #OldArt #JapaneseAntiques #Sencha #Crafts #TeaCeremony #TeaUtensils #Copperware #CopperProducts #Furo (tea ceremony brazier) #KyotoWare #TeaUtensils #Sencha #Senchado (Sencha tea ceremony) #SenchaUtensils
