摘要：In this paper it is presented the characterisation of tannins used in the vegetable tanning of twotypes of European historic and decorative leathers from Portuguese collections, damask leathersand gilt leathers, dated from the 17th and 18th centuries. Extracts prepared from collected leatherfibres were analysed by attenuated total reflectance – Fourier transform infrared (ATR-FTIR) spectroscopy.Results were compared with data collected from different reference vegetable tanningmaterials which, according to historic and technical literature, were used in Europe during theModern Age. This study allowed, in most cases, the characterisation of the tannins used to producethe studied decorative vegetable tanned leathers and, at the same time, the detection of chemicaldeterioration of leathers, particularly collagen hydrolysis, which was not visually perceived.
