虽然文献中已经报道了成千上万的考古青铜器分析，但比较它们的基础，特别是来自不同实验室的比较，是不可靠的。一项化学分析循环项目试图改善这种情况。两件古代青铜器被磨成细粉，经过筛分，混合成均匀的一团。从这个团块中随机抽取500毫克的样本进行了循环，并从21个实验室返回了结果。分析了48个元素；有些实验室只检测一种元素，有些则多达42种。变异系数（或相对标准偏差）范围从铜的4%到某些微量元素的200%以上。将结果制成表格，并建议在下次运行该程序时缩小结果范围的方法。
While thousands of analyses of archaeological bronzes have been reported in the literature, the basis for comparing them, especially those from different laboratories, is shaky. A round-robin project of chemical analyses was attempted to improve the situation. Two ancient bronze objects were milled to a fine powder, sieved, and mixed to a homogeneous mass. Samples of 500 mg each drawn randomly from this mass were circulated, and results were returned from 21 laboratories. Forty-eight elements were analyzed; some laboratories did only one element, some did as many as 42. The coefficient of variance (or relative standard deviation) ranges from 4% for Cu up to over 200% for some trace elements. The results are tabulated, and methods are suggested to narrow the spread of results in the next run of this program.
