摘要：In the contemporary art, the conservation of the original matter is not as important as the conservation of the authenticity of the work, because of this it is very important to know the artist and his work, to be able to conserve the most important values. In this process it is very important the documentation and the research. Therefore the criteria of restoration has changed, we can not conserve the patina of the contemporary art as a historic document, if this means the loss of the aesthetic value of the work. Nowadays the art is different, and therefore its conservation is different too.
