Our authentication process employs ultraviolet (UV) fluorescence examination at a wavelength of 365 nanometres (nm), following principles outlined in standard conservation practice (e.g., CIE Publication 15:2018 and Getty Conservation Institute Methods for Examination of Cultural Materials).
Purpose:
Ultraviolet examination assists in the non-destructive identification of modern restoration materials, synthetic pigments, adhesives, and surface alterations that are not visible under normal lighting. It is a diagnostic support method used in conjunction with stylistic, compositional, and provenance analysis.
