Video of the Städel Museum, Frankfurt

The Städel Museum's film gives you an insight into the work of restoration for paintings and modern sculptures. In the initial sequence up to 1:25, they use the ART X-RAY system.

Among the german museums, the Städel, officially the Städelsches Kunstinstitut und Städtische Galerie, is one of the most important. With a collection of approximately 3000 paintings from about 700 years of art history, hundreds of sculptures and photographs and an extensive reference library of about 10,000 volumes, the Städel impressess everyone interested in arts. So the choice to the Museum of the Year 2012 by the International Association of Art Critics AICA fell on the Städel in Frankfurt.

Stephan Knobloch, Leiter der Restaurierun am StädelmuseumStephan Knobloch is the head of the restoration of paintings and sculptures at the outstanding museum. Since 2012 he works with the ART X-RAY system from NTB:

"The University of Fine Arts - Städel School - offers their students an exceptional basis for their projects in restoration and preservation. In such a study the analysis of artworks today requires a lot of manual work. For example students have to determine the wood species of frames and to assess the conservation status of an artwork based on performed restoration work. Crucial for the value of a painting are mainly retouchings and fillings, which may differ in their very nature.
Through digital x-raying, an artwork can pass an identification procedure: Which artist created it? Is it the original or even a fake? In some cases it may also be a copy or a student work. So many paintings also conceal hidden works under the visible color layer. Leaded colors stand out clearly in the x-ray image.

In the practical work the ART X-RAY system provides many advantages:
Due to the digital x-ray, we have the results right away. Defects and other conspicous details can be seen immediately. It saves us a lot of time that we would otherwise spent with additional laboratory work. There are no longer costs for chemical methods and the film developement with high-maintenance equipment - X-ray film material becomes more and more expensive! And also, I am pleased that we have banished - by ART X-RAY - all chemicals for the development of x-ray films out of our work.

The simple design of the system allows operation without any special technical knowledge. NTB offers during the installation of the system, a technical introduction and is also accessible for any questions at any time."
