Abstract

The problem connected with the methodology of research on old binders remains unsolved. The reason of this situation raises from the impossibility of creating one formula according to which all old binders ally known. One might think that a simultaneous use of all the methods for research on binders coming from historical objects would guarantee complete information on the binders. At the same time the information would be helpful in restoration process, especially those of reconstruction would in the identifying of the causes of damages. A considerable difficulty with talking samples is an additional problem. This refers first of all to  plasters located below paintings, where the possibility of talking samples is very limited because of a possible damaging of the painting. It is especially do research which will provide maximum information, because after carrying out restoration works many marks may be impossible to remake. Therefore making a decision on the type of research one should find such information which will provide the line of further research. The introductory information may be collected through the observation of thin sections in transmitted light with a polarizing microscope. An analysis analogous to that which is done at the identification of rocks–petrography analysis.
