Art restorer

Still another use of EDTA is in the field of art restoration. Figure C shows before and after" photographs of Rodin s bronze sculpture The Thinker." This stood in front of the Philadelphia Rodin Museum for about 60 years prior to its restoration in 1992. Over time the sculpture had picked up a thick coating of insoluble CuS04 3Cu(OH)2(s). Application of a wet paste containing EDTA dissolved the coating by forming the soluble Cu(EDTA)2 complex.

Art forgeries are detected by chemical means. Art restoration and conservation is accomplished through applying the principles of solution chemistry. We have a true and faithful marriage of art and chemistry when we restore or conserve artwork and when we discover art forgeries. In these endeavors, art and chemistry will never be divorced. 

Make a list of several chemical formulas for substances used in painting, photography, clay sculpting, metalworking, and art restoration. 

The art restorer can work on restoring an art object for several months. This means daily contact with the restoring materials. The restorer s room needs excellent ventilation. The restorer should wear gloves to prevent skin contact with restoring materials. Eyes should be protected with goggles. Mainly, the restorer should read the labels on the restoration chemicals and adhere to toxicity advice. 

There are four aspects of art restoration where chemical knowledge is all important and these are the topics we will look at in this chapter. They are colour, analysis, restoration, and fraud. 

A definition of art conservation has been stated by Ben Johnson, Head Conservator at the Los Angeles County Museum of Art Conservation can be defined as the application of science to the examination and treatment of objects of art and to the study of the environments in which they are placed. Art restoration is the portion of conservation which deals primarily with the treatment of objects. It should be understood that restoration does not imply an attempt to return the object to its original state but rather to prevent deterioration of the original materials while respecting their integrity (I). ... 

As a paradigm for the evolving sophistication of laser ablation, the laser eraser described by Schawlow 30 years ago has now become a tool for graffiti removal, and more delicately for art restoration, e.g., paintings [32] and parchments [33]. 

Art does not last forever. It is damaged by events such as people sneezing on it, touching it, or by smoke during a fire. The repair of damage to artwork is the job of art restorers. Art repair is not always an easy task, because the materials used to correct the damage can also damage the artwork.

Value of these Copolymers in Art Restoration and Preservation. Currently, the present authors are involved in a unique application of radiation polymerization techniques where the present grafting work can be of value. Thus radiation polymerization is becoming increasingly useful in the restoration and preservation of art treasures (21, 22), particularly for materials of cellulosic origin. Methods now used Include impregnation of celluloslcs such as wood with acrylate monomers followed by Irradiation. More recent...

Another major application of the technique is in the analysis of ancient paints used in a particular period of history or a particular place. This is essential not only for the study of the pigments and materials used by different civilisations, but also for authenticating works of art, restoration work and in lawsuits involving damaged works of art. 

For the restoration of art objects the use of modern and well defined materials mainly polymeric materials rather then the use of traditional materials for art restoration is now widely recognized. Many scientists are interested in the arts visit museums and appreciate the beauty of the artistic expression of our heritage. The interests are rather diffuse and unorganized and it was thought important to focus the interests and knowledge into what is needed in art restoration and where we polymer scientists can contribute to the permanence of art objects through their maintenance and preservation. 

One of our problems that we have in art restoration is that relatively small amounts of materials, varnishes, glues, of very specific characteristics are needed. Ideally speaking it would be nice to have available one type of material for each type of painting and each period. From the commercial point of view, it is not justifyable to produce many types of small amounts of material. Consequently, the cooperation of industry for the preparation of these specialty polymers, polymers that would in most cases have to be tailor made, is limited. In the case of polymeric materials for electronic applications, it is much easier to arouse interest for polymers with low volume but with larger returns. It is one of the objectives of this discussion to call attention to the need of specific materials in art restoration and preservation and to alert the scientists and restorers to the importance of a bridge of knowledge in this field and for industry to become aware of the opportunities.
