Consolidation Tests

The National Museum of Anthropology (Museo Nacional de Antropologia, project partner MNAH) at Mexico City holds the second worldwide larger collection of the Teotihuacan archaeological site wall paintings (dating from 1-700 AD).

Consolidation tests in the framework of NANOFORART project have been performed on small samples of frescoes recovered in the year 2002 at Xalla, a large Palace Complex located near the Pyramid of the Sun at Teotihuacan (350-550 AD).

The aim of these tests was the assessment of new nanomaterials, specifically designed by other project partners for the consolidation of immovable works of art.

Detached wall-painting samples from the building Xalla in the archaeological area of Teotihuacan (Mexico). These samples, never treated before, showed powdering of the paint layer as evidenced by using a wet cotton-swab on the surface. Pictures show the application procedure of nanoparticles dispersion by brushing, followed by desalination with cellulose-pulp compress.
