Introduction： This patented design by Dayun is inspired by the aesthetics of the Song Dynasty, combined with innovative modern forms. Crafted with raw mineral glaze, high-temperature ceramic, and ancient techniques, its accordion-like pleats guide the tortoiseshell glaze to transform uniquely in the kiln - each piece bearing unrepeatable patterns that evoke the fluid poetry of city lights, exuding both luxury and contemporary flair. Ideal for daily use or as a cultured gift, its tortoiseshell-patterned glaze mirrors the auspicious markings of a turtle’s shell, symbolizing fortune and longevity.
