Application of new products for restoration

In the restoration works, the use of products compatible with the materials composing the heritage artworks is important. The majority of materials of Cultural heritage (ceramics, mosaics, mortars, stones) is made of natural inorganic raw materials, so it is crucial in the conservative intervention to use inorganic non-metallic compounds, that in some cases are the same components of the cultural heritage. For this reasons, we are setting up products gotten by modification of inorganic raw materials, such as the geopolymers. Colored geopolymers were used as musivae tesserae for filling of lacuna in the restoration intervention.In addition, moveable support made oflight -weighted geopolymer directly applied on restoration mortar was used for replacing of mosaic fragments.
