The authentication of an antique Russian icon requires layered analysis rather than stylistic intuition.
Our evaluation process begins with structural examination of the wooden panel: wood selection, grain orientation, tension lines and original battens. Natural aging patterns differ fundamentally from artificial surface distressing often found in later reproductions.
The levkas ground — traditionally composed of chalk and animal glue — must show organic interaction with the panel beneath. Micro-fractures follow structural movement rather than decorative regularity.
Pigment analysis considers mineral composition, oxidation patterns and layering technique. Traditional egg tempera reveals depth and crystalline structure that modern synthetic paints cannot replicate.
Iconographic coherence is equally essential. Each subject must align with canonical theological structure. Deviations may indicate later reinterpretations or non-traditional production.
Authentication is cumulative: no single element determines authenticity. It is the convergence of structure, material, technique and historical context that establishes credibility.
