Soluble salts play a key factor in damage to a variety of materials, including stone, ceramics and metals. Particularly, salt contamination can lead to weakening of porous materials through salt crystallisation events, and increases the rate of metal corrosion. Over time, this results in physical damage to affected objects and buildings. It is therefore important to be able to monitor the salt content of materials, in order to understand levels of salt contamination and the potential for damage to occur.

This research discusses the further development of the testing method for surface chlorides originally proposed by Piechota and Drake Piechota (2016) in their article “A simple survey kit for chloride detection on cuneiform tablets and other collections”. It introduces new and revised steps into the original protocol in order to make the achieved results semi-quantifiable, as well as identifying the limits of detection of the test kit. A comparison to alternative testing methods showed that comparable results were achievable using this methodology. The revised methodology was tested for efficacy on a range of salt contaminated objects, as well as on samples from buildings.
