as light meets matter under scrutiny

Spectrotech

Simpkins (claims genuine)

shows that the paint used in previous piece of art is also used in this piece of art, paint was made in the same room at the same time

uses fluorescence data to back his arguement, saying that the UV data of Pruschy may be not true because the artist would often revisit his works of art

the green used in this painting is very similar to a previous painting

Montoya (claims genuine)

pigments were used between pigments used during the period 1839-1906, he was alive in that period of time

absence of titanium, cadmium, barium, and manganese lines

Andersen (claims fake)

Cezzane was known NOT to have underdrawings, this painting had an underdrawing

Binder used is animal glue, which was also used widely after the death of Cezzane

Cadmium Yellow Lithopone was used in the painting which was not discovered until After Cezzane died

Pruschy (claims fake)

used UV spectrometry to determine the absorbtion of polyenes, which shows that it is not 100 years old

Wandless argues that polyenes residue may have been added after the painting was drawn

french curator

in 1995 concluded that there is likely to be no more works by Cézanne

Marden (claims genuine)

uses microscope to determine a smilarity in style with Cezanne

Does not use science, rather uses history, artistic analysis and visual analysis of painting to conclude that it is a genuine piece of art

ways to falsify a painting

Visually

not scietifically accurate as style could be imitated

IR spectroscopy

tests for anomalies beneath the paint

X-ray

examines composition of pigments

UV a. spectroscopy

dates pigments

Dr. Wandless

resorted to science in order to falsify painting

Dimitri

doubtfull initially

Colins

initially"feels" that it is infact the work of Cézanne

collector of art
