In the late period of the Liangzhu culture,finely incised,ground,and polished black pot-tery became popular,featuring unique imagery and great technical challenges,evolving into a new luxu-ry item.Existing research has mostly focused on the types and meanings of central motifs and paid less attention to technical and artistic styles.This new product was inspired by jade artifacts and shows traces of various technical and artistic traditions from the lower Yangtze region since the Hemudu cul-ture.In terms of content,similarities can be found between the incised decorations on black pottery and Liangzhu jade artifacts in composition,decorative elements,and themes,with similar artistic styles dat-ing back to the Hemudu culture.In terms of technique,the carving techniques used in jade artifacts pro-vided tools and methods for potters,and the polishing techniques may have been adopted to give black pottery a glossy finish.Cross-material artisanal technology exchange provides clues for further research on selecting techniques and artisan organization in Liangzhu craftsmanship.
