Models for long‐term glass alteration are required to satisfy performance predictions of vitrified nuclear waste in various disposal scenarios. Durability parameters are usually extracted from short‐term laboratory tests, and sometimes checked with long‐term natural experiments on glasses, termed analogues. In this paper, a unique potential ancient glass analogue from Sweden is discussed. The hillfort glass found at Broborg represents a unique case study as a vitrified waste glass analogue to compare to Low Activity Waste glass to be emplaced in near surface conditions at Hanford (USA). Glasses at Broborg have similar and dissimilar compositions to LAW glasses, allowing the testing of long‐term alteration of different glass chemistries. In addition, the environmental history of the site is reasonably well documented. Initial investigations on previously collected samples established methodologies for handling and characterizing these artifacts by laboratory methods while preserving their alteration layers and cultural context. Evidence of possible biologically influenced glass alteration, and differential alteration in the 2 types of glass found at the Broborg site is presented.

瑞典维克福特山岗玻璃预测：一种用于玻璃化核废料的预期长期改建类似物。

需要使用长期玻璃更换模型来满足各种处置方案下玻璃化核废料的性能预测。耐用性参数通常是从短期实验室测试中提取的，有时会通过对眼镜的长期自然实验（称为类似物）进行检查。本文讨论了一种来自瑞典的独特的潜在古代玻璃类似物。在Broborg发现的Hillfort玻璃作为玻璃废玻璃类似物代表了一个独特的案例研究，与在汉福德（美国）近地表条件下放置的低活性废玻璃进行了比较。Broborg的眼镜与LAW眼镜具有相似和不同的成分，可以测试不同玻璃化学成分的长期变化。此外，该站点的环境历史记录也有据可查。对先前收集的样本进行的初步调查建立了通过实验室方法处理和表征这些文物的方法，同时保留了它们的蚀变层和文化背景。提供了可能受到生物影响的玻璃蚀变的证据，以及在Broborg站点发现的两种类型的玻璃的差异蚀变的证据。
