本文测定了四个考古遗址铁器的重量体积比。它示出了如何可以使用这个比率来确定金属铁的存在或不存在的腐蚀文物。实验表明，完全矿化的铁制品通常比保留金属芯的铁制品含有少得多的氯化物。加速腐蚀实验表明，完全矿化的铁制品不会受到保留金属芯的物体上所见的物理劣化的影响。因此，建议用重量体积比来预测铁制品开挖后的稳定性。由于需要较少的环境控制，因此可以降低储存成本。检查了一些氯化物水溶液提取方法以确定重量：体积比是否影响其效率，但结果不确定。
Abstract The ratio weight:volume has been determined for ironwork from four archaeological sites. It is shown how this ratio can be used to determine the presence or absence of metallic iron in a corroded artifact. Experiments show that totally mineralized ironwork generally contains much less chloride than does ironwork retaining a metallic core. Accelerated corrosion experiments show that totally mineralized ironwork is not subject to a physical deterioration seen on objects retaining a metallic core. Therefore it is suggested that the ratio weight:volume can be used to predict the stability of ironwork following excavation. Costs of storage can be reduced since fewer environmental controls are necessary. Some aqueous chloride extraction methods were examined to determine if the weight:volume ratio influenced their efficiency but results were inconclusive.
