Management methods for the preservation of art works

In terms of preservation of the collection, in order to maintain the good conditions of them, they need to be checked regularly from the moment when they are created, or from when they are displayed. In other words, the best way is to prevent severe damages before they happen, as in human case, we prevent disease before we get sick. However, the collection must be inspected and treated by professionals as soon as minor damages are found or they are about to be damaged.

Art Material Analysis

The optical analysis of paintings is carried out through naked eye observation and analysis using apparatus such as infrared and ultraviolet photography, and X-ray Diffraction Analysis

Infrared Analysis

Infrared light tends to respond to carbon elements like charcoal and ink, penetrating the layers of paint to reflect or absorb sketches and inscriptions underneath the paint layer. An infrared photograph of <Nude> by Oh Ji-ho shows inscription under the painting layer.

Ultraviolet Analysis

Ultraviolet photography investigates the surface condition and the luminescence of painting, allowing conservation specialists to see whether there is a varnish coating on the painting, as well as color retouching, painted-over marks, and any type of pollutants. In <Image of Wife> by Oh Ji-Ho, covered parts are shown through ultraviolet rays.

X-ray Diffraction Analysis

X-ray Diffraction Analysis allows conservation specialists to see whether there is layers of paint under the surface, and to observe the artist’s unique brush strokes. It also shows condition of cracks and damages to the paint layers. The X-ray analysis of <Landscape> by Oh Ji-ho demonstrates that a female nude painting is drawn on the coat underneath the present work.

Videomicrography Analysis

Videomicrography analysis is carried out for component analysis of paint and pigment used in painting. The videomicrogaphy analysis on the following painting demonstrates that what seems blue or red is actually a mixture of other colors.
