ABSTRACT Reigate stone was extensively used in medieval London and is prone to rapid decay. A variety of different conservation treatments has been applied in the past; in many cases, these have not mitigated on-going decay. This paper presents an overview of wax, limewash, silane and ammonium tartrate treatment at the Tower of London and Hampton Court Palace. Documentary analysis and visual inspection indicate that whilst these methods have provided protection to some stones, no single method has resulted in the protection of all stones. Non-destructive and minimally-destructive testing is used to more closely assess the effects of ammonium tartrate treatment. The results imply that inherent stone mineralogy, past decay pathways and/or present environmental factors are a greater influence on on-going decay than treatment histories.

评估汉普顿宫和伦敦塔雷盖特石保护的长期成功

摘要 Reigate 石在中世纪的伦敦被广泛使用，并且容易快速腐烂。过去曾采用过多种不同的保护措施；在许多情况下，这些并没有减轻持续的衰减。本文概述了伦敦塔和汉普顿宫的蜡、石灰水、硅烷和酒石酸铵处理。文件分析和目视检查表明，虽然这些方法可以保护一些宝石，但没有一种方法可以保护所有宝石。无损和最小破坏性测试用于更密切地评估酒石酸铵处理的效果。结果表明，与处理历史相比，固有的石材矿物学、过去的腐烂途径和/或当前的环境因素对正在进行的腐烂影响更大。
