Zhangqiu Qing granite fire-burned surface, mined from high-quality veins in Zhangqiu, Shandong, is forged by natural geology and carved by fire-burning technology. It is a high-end decorative stone with both aesthetic and practical value, giving unique charm to buildings and landscape spaces.

By burning the surface of the stone with high-temperature flames, the internal crystals burst, forming a rough and concave natural texture. The board surface is based on a deep blue-gray color, with finely distributed silver-white and gray-black mineral particles, like stars falling in the night sky. The rough texture weakens the reflection of light, creating a calm, simple and layered visual effect. Each board has a unique texture due to the difference in natural veins, like an artistic code written by nature
