Mammoth tusk composition with Cantonese ball "Harmony. The Ercikan left column"28 spheres

The Cantonese bone ball, also known as the "ghost ball", is one of the most characteristic types of Guangzhou carvings, formed back in the Ming Dynasty. Its uniqueness lies in the fact that a single fragment of bone is hollowed out into a multi-layered sphere with intertwining openwork shells. Each layer is finely worked out with its own through-the-wall ornament and can freely rotate inside the subsequent one, creating the impression of lightness and almost weightless transparency.

The Cantonese ball is considered the pinnacle of local school craftsmanship and an important part of China's national intangible cultural heritage. Modern works often use a single mammoth tusk, which makes it possible to create complex multi-layered structures with filigree precision. The most important indicator of the master's level is the number of inner spheres: the more layers are enclosed in one ball, the higher the technical complexity and the more virtuoso the work is considered. Creating a large number of freely rotating shells requires exceptional calculation accuracy, error-free tool ownership and many years of experience.

The process of hollowing out a single multilayer sphere is extremely laborious and involves a high risk of material damage at any stage. It is this technical complexity combined with artistic ingenuity that gives the "ghost ball" its unique charm and makes each piece a testament to outstanding craftsmanship.
