Among the methods for examining paintings, ultraviolet fluorescence is certainly one of the most popular and widespread. This technique is mainly used to determine the state of deterioration of works and, in particular, to check the existence and extent of non-original parts of the paint layer.
Varnishes based on natural resins, glues, oils or other substances of organic origin such as egg white (often applied to protect paintings on panels) will also be highlighted, allowing for a verification not only of their presence, but also of their superposition and their homogeneity.
During cleaning operations of a painting, the repeated control under Reskolux ultraviolet lamps gives the possibility to check, at any given time, the work in progress, the degree of homogeneity and thinning of the varnish, the presence of additional layers, as well as stains of glue or other materials, residues of previous interventions. In other words, UV lamps allow a better understanding of the subject under study.
