In the recent preservation and research works a good deal of attention has been paid to the salting of objects the state of which deteriorates with the accelerated weathering. As the cause of salting may be quoted preservation processes carried out with application of media containing or producing water-soluble salts, and also the moistening of objects, further the action of biological factors, and the air contamination by combustion gases. The mechanism of stone destruction by water-soluble salts consists in solving of its components in basic or acidic products of salt hydrolisis and in the blowing action of hydratating or crystallizing salts in which the actions an important part is being played by hygroscopic properties possessed by the salts themselves. Thus, the preservation of historical monuments endangered with destruction in effect of their salting should, above the all, comprise the revealing and removing the causes of their salting, the salt extraction, and finally, where necessary, their consolidation.
