This paper investigates the use of Optical Coherence Tomography (OCT) and Short-wave Infrared (SWIR) spectral imaging to study the deterioration of a Limoges enamel panel. Limoges enamels are formed of glass layers applied on a metal substrate and are prone to 'glass disease'. However, the level of deterioration in Limoges enamels is generally difficult to assess visually. In this study, SWIR was used to produce a hydration level map of the enamel, which was coupled with virtual OCT cross-sections. The study shows a good correlation between levels of hydration and structural damage over the enamel panel. Hydration mapping allows visualisation of structural damage across the entire enamel in one image.

“…Analysis of the composition of the flutes and determination of the materials used can offer more insight into how they were created and can also help with conservation and characterization matters. The composition of the flutes has been associated with their state of conservation, as flutes made with crystal glass rich in lead are better conserved than those with a higher K 2 O concentration, which are less resistant to attack by moisture [3]. In alkali-rich glasses, moisture and changes in humidity can cause sodium or potassium ions to leach into the glass.…”
