SCIENTIFIC ANALISIS 

Chemical analysis:

- Support framework: gypsum and silicates (these in a very small proportion). Thickness: 100 µm..

- Layer of paint (bluish-black): calcium carbonate, carbon, soil, copper pigments and gypsum in very small proportions.

- It was impossible to detect significant quantities of organic matter that would permit the use of a possible agglutinating compound.
