Colourimetric analysis of results of laser cleaning in case of metal artworks
Języki publikacji
Abstrakty
Na podstawie doświadczeń autorów związanych ze spektrofotometrycznymi i kolorymetrycznymi analizami procesów czyszczenia różnych materiałów w artykule podjęto próbę oceny przydatności kolorymetrii, jako metody oceny efektów czyszczenia laserowego blachy miedzianej, zdjętej podczas restauracji poszycia dachowego Pałacu w Wilanowie w Warszawie. Pomiary kolorymetryczne poprzedzone były wnikliwą analizą materiałową próbek i ich nawarstwień. Przeprowadzone analizy pozwoliły na sformułowanie szeregu wskazówek dla stosowalności metody przy ocenach skuteczności i wpływu oddziaływania promieniowania laserowego na powierzchnie metaliczne w obecności zmian spowodowanych przez zanieczyszczenia atmosfery. W szczególności kolorymetria może być dobrym narzędziem badawczym w przypadku usuwania pojedynczych warstw korozyjnych oraz czyszczenia osadzeń atmosferycznych na pozłotach.
Paper presents an attempt to validate application of colourimetry as a method of examination of laser cleaning of the copper sheet, taken from the roof of the Wilanów Palace in Warsaw during its restoration. Analysis has been made on the base of authors experience in spectrophotometric and colourimetric analysis of laser cleaning processes in case of different historical materials. Material analysis of samples and encrustation preceded colourimetric surface measurements. Complex analyses allowed formulation of several indications for applicability of the colourimetric method in the evaluation of its effectiveness an influence on metallic surfaces in the presence of degradation caused by atmospheric pollution. In particular, colourimetry could be considered as a proper diagnostic tool in case of removal of single corrosion layers as well as removal of atmospheric deposits on gilding.
