Colorimetry, LIBS and Raman Experiments on Renaissance Green Sandstone Decoration During Laser Cleaning of King Sigismund’s Chapel in Wawel Castle, Cracow, Poland
Measurements aimed at optical characteristics of the basic building material of the Renaissance dome of King Sigismund’s Chapel in Wawel Castle are described in the paper. Colorimetric measurements, LIBS investigations and Raman effect measurements were carried out. LIBS spectra of encrusted and clean (fresh fractured) grey-greenish Myslenicki sandstone are presented. Raman spectra and reflection coefficients as well as L, a, b coordinates for several samples are also shown.
