The jadewares of Sanxingdui culture are not only large in number but also complex in kinds. They include ritual artifacts and daily utensils made of high quality jade like jade earring,jade bracelet, jade pipe, jade beads, jade pendant etc. as well as jade arms or tools like jade spear, jade daggar-axe, jade axe, jade chisel and so on. The latter kind of jadewares looked new and sharp when first excavated and are mostly unearthed from the sacrificial pits. They should be ritual articles but not jadewares for practical use. Some tablets are even as long as 90cm and made of very thin jade plate, showing that their manufactural skills like plate-cutting, sculptural carving and grinding already reached very high standard.
