Cezanee painting

The analysis of a suspected Cézanne painting incorporates various scientific techniques and art historical perspectives to determine its authenticity. Infrared spectroscopy reveals that certain binding materials and pigments in the painting are consistent with those used in the 19th and early 20th centuries, including cadmium-based yellow pigments.

Cezanee painting

Cezanee painting

Fake

no evidence from Fluorescence for polyene emission fom the painting although it should be sensetive than UV absorption
Unkown source
cezanee didn't draw underpainting
Infrared Spectroscopy(IR)
the binder is used is animal glue binder and it is used in the nineteeth century till 1940s
this mix wasn't there till 1927
Yellow areas shows cadmium-based composed of cadmium yellow lithepone(cadnium-barium)
UV spectrum
painting showing absorbance of 0.6,so it is not like to be from 100 years ago
Substantial absorption from apolyene

Authentic

XRF(X ray fluorescence)
the pigment were known before and during the cezanee time
elemental compositions of the painting match the composition of pigment during 1839-1906
Fluorenscence data
Made in the same studio
use the same orange pigments(very similar)
green areas in the trees and orange are as bright as Cezanee paintings
Art historians
His paintings weren't from the nature but scratching in his studio
painted in late 1880s
It gives the feeling of Cezanee
the painting is similar to one of Cezanee workings
unsigned and many of cezanee paintings weren't signed
Polyenes could be contaminated caused by soot or burning lamp
