Thermal Properties And Staiblity Of Catalan Modernist Blue And Green Enamels

Stained glass is a fragile component of our cultural heritage. In particular, the stained glass produced during the last decades of the 19-20th centuries, which is characterised by the use of a new type ready-to-use-enamels. This study analyses the collection of materials used in one of the most important stained glass Modernists workshops in Barcelona. The chemical composition is determined (and pigments identified) by means of Laser Ablation Inductively-Coupled Mass Spectrometry and X-Ray Diffraction and the thermal properties of the enamels measured by Differential Scanning Calorimetry and Hot Stage Microscopy.
