Protection of stone monuments using a brushing treatment with ammonium oxalate

This data was used for creation of figures and tables in work named "Protection of stone monuments using a brushing treatment with ammonium oxalate". Data was gathered using synchroton based µXRD and µXRF end stations at SOLEIL synchrotron in Paris, and Elletra synchrotron in Trieste. Interpretation of data shows that stones that are different in their porosity need different brushing time to create sufficient protective layer on stone monument. If the treatment is too long it results in creation of microcracks that subsequently destroy the protective layer.
