Located　in　Pujiang,　Chengdu,　China,　more　than　four　hundred　artifacts　were　unearthed　during　the　excavation　of　the　Warring　States　(the　Warring　States　period　lasts　from　475　to　221　BC)　ship-shaped　graves　in　2016.　The　compositional　and　metallurgical　feature　of　the　unearthed　vessels　are　still　unclear.　Archaeologists　and　conservators　are　puzzled　by　such　problems　that　need　to　be　answered　by　systematic　scientific　studies.　Fifty　one　samples,　either　from　the　matrix　(26　samples),　or　from　the　corrosion　part　(25　samples)　of　25　unearthed　bronze　vessels,　were　carefully　collected　from　the　fallen　part　of　the　bronze　vessels　for　analysis.　Technical　methods,　such　as　OM,　SEM-EDS,　XRD　and　Raman　Spectroscopy　were　adopted　for　compositional　and　metallurgical　characterization　of　the　bronzes,　as　well　as　identification　of　the　corrosion　products.　The　bronzes　are　Cu-Sn-Pb　trinary　alloys　with　typical　casting　microstructure.　The　proportion　of　Sn　are　in　accordance　with　excavated　bronze　vessels　in　surrounding　areas.　Recycling　isn＇t　involved　with　the　production　of　such　vessels.　Layered　structure　of　the　corrosion　products　was　observed.　Different　corrosion　products　were　identified　as　Cu2CO3(OH)(2),　Cu2O,　CuSO4　center　dot　5H(2)O　SnO2,　PbSO4　and　PbCO3.　The　findings　help　us　gain　insights　into　the　bronze　manufacturing　in　Bashu　district,　as　well　as　the　corrosion　behavior　in　certain　condition.
