Ageing of historical objects often results in changes in the optical properties of the constituent materials. Imaging spectroscopy (IS) can be a valuable tool for monitoring of such changes although it has so far rarely been used in a quantitative manner. The purpose of research presented in this paper is to evaluate its detection limit [...]

Tjaša Rijavec, Matija Strlič and Irena Kralj Cigić recently published the invited feature paper “Plastics in Heritage Collections: Poly(vinyl chloride) Degradation and Characterization” in Acta Chimica Slovenica. Museums and galleries house significant collections of objects and contemporary art made of plastic materials, many of which undergo rapid material change. Degradation results in visible discolouration, stickiness [...]
