[New Book] One Stone a Day

[Financial News] Porous pumice can float on the sea and serve as a raft for small marine organisms. One Stone a Day, written by earth science teacher Kwon Hong-jin and mineral collector Lee Ji-seop, tells stories connected to rocks through 365 photographs and short pieces of writing.
The book features one rock, mineral or geological phenomenon for each day from January 1 to December 31. On March 30, “Pencil Day,” graphite, a material used in pencil leads, makes an appearance. It also includes examples from Korea, such as pillow lava along the Hantan River and columnar joints at Mudeungsan.
The book also explores cultures associated with rocks, including the “Pet Rock,” a pet stone that became popular in the United States in the 1970s, and the Haechi statue at Gwanghwamun. The authors say readers can grow closer to rocks by first noticing their colors, patterns and feel to the touch, even if they do not know their names. Readers can look up rocks that interest them using the classification chart and glossary.
