Heritage scientists have debuted a revolutionary Carbon-Nano sealant designed to protect the famous Roman mosaics of El Jem and Utica in Tunisia. As rising sea levels and groundwater salinity threaten to dissolve the limestone and marble tesserae, this new technology creates a breathable, microscopic barrier that prevents salt crystallization while allowing moisture to escape the stone.
Developed through a partnership between Tunisian heritage authorities and European tech labs, the sealant is applied using a specialized misting process that does not alter the aesthetic of the artwork. This preservation breakthrough is being hailed as a vital tool for coastal heritage sites worldwide that are facing the dual threats of chemical erosion and humidity due to climate change.
