The chemical deterioration of glass in museum collections is a large problem for conservators and curators. Objects of unstable composition typically show changes in appearance such as the accumulation of moisture on the surface and microcracking, which may render an object unfit for display or even cause its complete disintegration. The identification of unstable glass objects is essential for their preservation as it allows for the implementation of targeted conservation strategies. However, as yet no straightforward method exists. Guus Verhaar focuses on the early stages of glass deterioration.
