The study of the combined use of two inorganic mineral treatments on a stone of cultural heritage relevance by micro x-ray diffraction and m

This experiment aims at studying for the first time the effects induced by the combination of two inorganic-mineral consolidating treatments on a carbonatic lithotype of high artistic and historical relevance by micro X-ray Diffraction and micro X-Ray Fluorescence. In this research, we will explore the potential of AmOx and DAP treatment on Noto limestone (Val di Noto - Siracusa, UNESCO’s World Heritage List) which is a porous calcareous material composed of calcite in micritic size. The main focus will be obtaining crystal-chemical information on the newly formed phases on pore walls and monitoring their distribution and penetration inside the substate. From these results, we expect to open the path to new conservation strategies and supply crucial indications for the restoration of natural and artificial carbonatic substrates supporting the application of inorganic-mineral treatments on worksites.
