Resumen:
A study of a ceramic vessel from San Lorenzo Tenochtitlan, Veracruz, Mexico (Early Formative 1550-900 b.C.) was developed using three selected analytical methods: Petrographic thin section, X-ray Diffraction and Scanning Electron Microscopy. The results suggested, that the soil weathering processes on the ceramic vessel generated phenomenons, such as an increase in porosity, a decrease in bulk-density and loss in structural stability. On the other hand, the presence of amorphous materials (SiO2, FeO3) in the soil, interacted with the ceramic giving it a natural consolidation. The consequences of our study are discussed in detail.
