X-ray Earlier work can be detected underneath surfaces of paintings using a method of forensic authentication known as x-raying. A painting can be found to be not authentic if the image below the other image depicts more modern objects when the painting is claimed to have been completed in a different era. Often times an artist will reuse a canvas, which can also be detected by conventional x-ray because it determines if an object has been altered or re- paired. One painting, Portrait of a Woman, was attributed to Goya. However, x-rays taken in 1954 found that there was another portrait underneath the original work. Diffraction was used to determine that zinc white paint was used in the lower painting, which was invented after Goya’s death and therefore a fake. Portrait of a Woman, Attributed to Goya Did You Know? ● There are two types of x-ray used in art forgery detection: diffraction and fluorescence. ● Diffraction is when the object bends the x-rays and is most useful in analyzing the different components in paint. ● Fluorescence is when the object is covered in radiation to cause it to emit x-rays and reveals information about the metals used in sculptures.
Dendrochronology Dendrochronology is a scientific method known as tree-ring dating. The technique came into use during the early part of the 20th century and was discovered by A.E. Douglass from the university of Arizona. Knowing the age of a tree is important to art historians because it allows them to date the panel paintings and may indicate where the painting was done based on the type of wood. Panels are trimmed of the outer rings from the tree and usually only consists of a small radius of the trunk, so often only the earliest possible date can be determined for the actual arrival of a sea- soned raw panel. This process can be used on any wooden object, but it may not be very useful because it is necessary for there to be about a hun- dred rings to determine the age accurately. Eggcaetera by Pascal Oudet is not a forged piece of artwork and this can be verified through the use of dendrochronology.
