摘要

铜合金考古文物的变质和保存程度取决于几个相互作用的因素,这些因素从文物被埋葬时开始,并继续在博物馆储存。已经开始的老化和退化过程可以减缓,但不能完全停止。考察了铜合金种类和博物馆环境储存条件对变质过程的影响。使用非破坏性技术,如便携式XRF和射线摄影,以及挖掘报告中的数据,检查了带有三角形脚的弩胸针。利用ecmatenotebook软件对收集到的博物馆存储环境数据进行了分析。根据分析结果,采用风险评估法计算未来保存水平。大多数被检查的胸针都是黄铜制成的,保存状况相当良好。脚和针是损坏最严重的部分。未来相对湿度高(高达80%)的储存条件对处理过的和未处理过的胸针构成很大的风险。

Assessment of the deterioration process of copper alloys: a case study of Central Lithuanian crossbow brooches with a triangular foot
The deterioration and degree of preservation of copper alloy archaeological artefacts depends on several interacting factors that began when the artefacts were buried and continue in museum storage. Ageing and deterioration processes that have begun can be slowed, but not completely stopped. The influence of the type of copper alloy and museum environment storage conditions on deterioration processes was investigated. Crossbow brooches with a triangular foot were examined using non-destructive techniques such as portable XRF and radiography, as well as the data from excavation reports. The collected data on museum storage environment was analysed using the software program Eclimatenotebook. Based on the results of this analysis, the future preservation level was calculated using the risk assessment method. Most of the brooches examined were made of brass and were in a fairly good condition. The foot and pin were the most damaged parts. Future storage conditions with a high relative humidity (up to 80%) pose a great risk to the treated and untreated brooches.
