It is typically made from stone, ceramic, or other materials and serves as a surface for grinding ink sticks into liquid ink. Artists and scholars use inkstones to create the perfect consistency of ink for their brushwork, making it an essential item in the practice of Chinese calligraphy and Japanese sumi-e. Inkstones come in various shapes and sizes, often featuring intricate designs or inscriptions. They are not only functional but also considered works of art themselves. Collectors appreciate antique inkstones for their craftsmanship and historical significance, linking them to the rich cultural heritage of East Asia.
