自20世纪70年代初以来，考古学家、保护人员和策展人已经转向出版的短期和长期保护考古金属的方法指南。其中大部分内容都出现在无处不在的急救手册中，最近的一本是1998年出版的。所有指南的中心信息都是在挖掘后干燥金属，并通过使周围环境干燥来防止金属在储存期间的腐蚀。这已被证明对铁至关重要，有报道称，由于不适当的储存环境，会导致铁的灾难性损失。长期以来，人们一致认为，一种有效的、低成本的干燥方法是用干燥剂将人工制品包装在盒子里。尽管关于如何实现这一目标的细节的建议随着时间的推移而不断发展，但没有改变的是，所提出的方法缺乏量化的证据。根据对该部门当前实践的调查，本研究定量调查了为保存遗产金属而创建干燥小气候所涉及的许多变量。本文介绍了一系列商用盒子的气密性评估结果，干燥剂的最佳质量，外部环境的影响，以及用硅胶干燥潮湿物体的效率和风险的初步数据。第二篇论文将报告堆垛箱对其密封性的影响，并提供有关湿度指示卡的准确性和长期可靠性的数据。从干燥存储硬件和方法的实验室测试中产生的指导被设计为可实现和适应性强。将这些发现与铁制品的腐蚀速率数据相结合，可以计算存储过程中决策对物体的风险升级。总之，这些论文为急救提供了基于证据和以实践为重点的更新。
Since the early 1970s, archaeologists, conservators, and curators have turned to published guidance for methods of safeguarding archaeological metals in the short and long term. Much of this has appeared in editions of the ubiquitous handbookFirst Aid for Finds, the most recent of which dates to 1998. A central message across all guidance has been to dry metals post-excavation and prevent their corrosion during storage by desiccating the environment around them. This has been proven crucial for iron, with reports of catastrophic loss of collections arising from inappropriate storage environments. There has long been agreement that an effective, low cost option for desiccation is the packing of artefacts in boxes with a desiccant. Though advice on the details of how to achieve this has evolved over time, what has not changed is the lack of quantified evidence for the methods proposed. Informed by a survey of current practice in the sector, this study investigated quantitatively the many variables involved in creating desiccated microclimates for storage of heritage metals. This paper presents the results of an evaluation of the airtightness of a range of commercially available boxes, the optimum mass of desiccant, the effect of external environments, and preliminary data on the efficiency and risk of drying damp objects with silica gel. A second paper will report the effect of stacking boxes on their airtightness and present data on the accuracy and long-term reliability of humidity indicator cards. The guidance arising from laboratory testing of the hardware and methods for desiccated storage is designed to be achievable and adaptable. Combining these findings with corrosion rate data for iron artefacts allows the escalation of risk to objects from decisions in the storage process to be calculated. Together, these papers offer an evidence-based and practice-focused update toFirst Aid for Finds.
