Here are six pieces of antique ink, likely purchased by my mother, who ran a calligraphy class until about 25 years ago (see photo 1): "Top Left" 【鐵斎翁書画寳墨】 (Made by Shanghai Ink Factory, boxed) 35g (97mm x 23mm x 10mm) Unused, but cracked. (Photos 3-6) "Bottom Left" 【大好山水】 (Made by Hu Kaiwen of Huizhou, boxed) 59g (119mm x 29mm x 11mm) Partially used, with some cracks. (Photos 7-9) "Center Top" 【好文】 (Made by Bokundo, in a dedicated case) Purely plant-based pine smoke ink, Hyakusen-boku (Selected Ink) 119g (80mm x 73mm x 15mm) Appears to be 8-cho type, but slightly used. Also, there is some dirt on the surface. (Photos 10-13) "Center Bottom" 【老紫中庸】 (Made by Bokundo, in a dedicated case) 147g (108mm x 63mm x 15mm) Partially used, but is a high-grade pine smoke ink and a Hyakusen-boku (Selected Ink).
