The proposed special issue concerns the possibility of creating a specific series dedicated to the materials of cultural heritage, considering their origin, their use and applications over time, their degradation and the solutions for their conservation and restoration. The approach will allow to address the proposed topic in a multidisciplinary way considering archaeological, artistic and conservation studies involving different researchers and experts such as architects, archaeologists, conservation scientists and restorers. The proposed special issue will thus become a reference for a wide audience and reach a wide diffusion. As regards the first special issue proposed, considering the widespread diffusion of different countries and the great problems of chemical, physical and mechanical conservation, the material examined is raw earth (mud). The following research subjects are indicated here as possible topics of interest: Nature of the raw materials used in Earth Architecture; Historical, Architectural and Archeological approaches; Structural and mechanical studies; Chemical, physical, biological, geological issues; Conservation and restoration approaches and studies; New materials for the conservation of Earth Architecture; Engineering solution for the conservation of Earth Architecture. This Special Issue will also be open to contributions dealing with other subjects related to the major research themes mentioned above.
