Concentrated, hard mixture of silt and sand that could hold relics such as porcelain, bronze pieces and coins from the Song Dynasty (960-1279) are cleared from three parts of Nanhai-I's wreckage to help position the open caisson, or steel box. About 25 tons of solid silt is cleared and 390 pieces of relics sorted before the ship is lifted.
