The Cezanne Painting
The evaluation of a painting believed to be by Cezanne involves a series of scientific tests to determine its authenticity. Various analytical methods such as IR spectrum, fluorescence, and XRF data are employed to assess the materials and techniques used in the artwork.

The Cezanne Painting Fake IR indicates the presence of an underdrawing which, if true, would make the painting a fake The IR spectroscopy indirectly shows the presence of cadmium and barium which were not used untill 2o years after Cezanne died The UV spectrum test shows that the Polyene absorbance is 0.6 while it should be around 0.15 Not likely to be a 100 years old The brushwork is indistinguishable from other paintings of Cezanne from that period Authentic Floresence didn't show any emission of Polyene Florescence showed brighter emissions in dark green and orange areas which were similar to other Cezzane paintings XRF proved the absence of cadium, barium, titamium and managanese which were not present in Cezanne period of time. The XRF data showed that the painting composed of elements that were used during Cezanne period. IR spectrum proves that the bider is animal glue-based which was used in Cezanne's period The heavy palette knife strokes are specially characteristic of Cezanne's period The Environment could contribute Polyene The composition is very characteristic of his constructivist phase in the late 1880s
