The Vinland Map, supposed evidence of the Viking discovery of America long before Columbus, was proclaimed a forgery after the detection in the ink of titanium white, a modem pigment (see Pigments, inorganic) (13). Subsequendy, however, after another analytical study, the interpretation of the eadiet results has been questioned, and the matter of authenticity of this unique document stiU remains an open question (14,15). 

Fleming, S. J. (1975), Authenticity in Art The Scientific Detection of Forgery, Institute of Physics, London. 

Digital authentication is a new method recently used to detect art forgeries. A high resolution digital scan is made of an artwork under scrutiny. Then a statistical model of an artist is built up from scans of the artist s authentic works. A comparison is made between... 

Qualitative chemistry is an area of chemistry concerned with identifying substances. In Activity 9.1 you will perform a qualitative analysis to detect the presence of certain ions that, in turn, may reveal an art forgery. The ions could come from paints that were not available at the time of the artwork. In this qualitative analysis, metal ions (cations) and nonmetal ions (anions) are reacted with solvents and with each other. Then the cations and anions present are identified by the products produced. In addition, flame tests and pH determinations are used to identify ions. Qualitative analysis is an engaging opportunity for you to develop experience with chemical change and review solubility principles. Nowadays, however, most of the time a chemist analyzes a substance to detect ion content using quantitative analytical computerized instruments. 

Students will explain how qualitative ion analysis can be used to detect art forgeries. 

Either through instrumental analysis or qualitative analysis, the forensic chemist can reveal the presence of ions in a paint chip from an artwork and use the ion information to detect an art forgery. 

Students will distinguish between an art forgery and the real painting and discuss methods of detecting art forgeries. 

Students will detect an art forgery through chemical, ultraviolet, and paint-chip analyses. 

In order to detect an art forgery, why is detection of paint layering or mixing not conclusive evidence ...
