I am organizing the belongings of my grandfather, who was a calligrapher. It is a very large kettle. It seems to have been used as a tea kettle during tea ceremonies and to boil water when serving tea by the irori (sunken hearth). Height to the knob: 21.5 cm Diameter: 26 cm Weight: 2.9 kg Width: Approximately 26 cm Overall reddish-brown color. There is something like verdigris on the bottom exterior, so I believe it is made of copper. It is a good quality item from a long time ago.
