Mortar: Outer diameter: Approximately 215mm Inner diameter: Approximately 175mm Overall height: Approximately 110mm Inner height: Approximately 90mm Weight: 2.7 kg Pestle: Length: Approximately 210mm Maximum diameter: Approximately 55mm Weight: 0.5 kg Dimensions and weight are approximate values. I used this for a while as a hobby to crush silica sand and walnuts. Because the crushed materials were not very hard, the inner surface of the mortar does not have noticeable scratches, and there are no significant irregularities. It has been washed with water after being rubbed with fine silica sand. Please check the condition in the photos. The bottom (outer surface) has some brownish stains, but these were present from the time of purchase. They are probably marks from contact with the metal plate used as a tray for the mortar after firing. With an inner diameter of approximately 175mm and an inner height of approximately 90mm, it is relatively large, which is an advantage as it allows you to crush materials without scattering them. I don't clearly remember the purchase price, but I think it was around 12,000 yen. Thank you for looking.
