Chinese Seal Carving (Chop-Making)

篆刻 (Zhuan Ke) / 印章 (Yin Zhang)

Chinese seal carving (zhuan ke) is the ancient practice of carving Chinese characters in reverse intaglio into stone, ivory, jade, or wood to create personal name seals (chops) used for official signatures in Chinese cultural practice. The Singapore seal carving tradition — practiced by specialist chop-makers in Chinatown and along traditional Chinese commercial streets — uses zhuan shu (seal script) and other classical Chinese scripts carved with a specific blade technique that exploits the material's natural cleavage planes to produce clean, crisp characters. Seal carving requires simultaneous mastery of classical Chinese calligraphy (knowing the correct character forms), mirror-image spatial visualization (the carving is in reverse), and material-specific blade control (stone, ivory, and jade each carve differently). The tradition is endangered in Singapore with most chop-making now done by machine engraving.
