Two fresh and artificially aged triterpenoid varnishes, dammar and mastic, were tested. Nonlinear imaging techniques have been employed as a new diagnostic tool for determination of the exact thickness of the affected region due to artificial aging of the natural varnishes. The measured thicknesses differ from the calculated mean penetration depths of the samples. These nondestructive, high resolution modalities are valuable analytical tools for aging studies and they have the potential to provide unique in-depth information. Single photon laser induced fluorescence measurements and Raman spectroscopy were used for the integrated investigation and analysis of aging effects in varnishes.

assessment of degradation of the outer protective layers of painted artworks as a function of depth due to aging.
Two fresh and artificially aged triterpenoid varnishes, dammar and mastic, were tested. Nonlinear imaging
techniques have been employed as a new diagnostic tool for determination of the exact thickness of the affected
region due to artificial aging of the natural varnishes. The measured thicknesses differ from the calculated mean
penetration depths of the samples. These nondestructive, high resolution modalities are valuable analytical tools
for aging studies and they have the potential to provide unique in-depth information. Single photon laser induced
fluorescence measurements and Raman spectroscopy were used for the integrated investigation and analysis of
aging effects in varnishes.
