The LATAM International Course on Stone Conservation: Observation, Documentation and Diagnosis recently concluded in Mexico. During the three-week course, eleven participants from Colombia, Guatemala, Honduras, Paraguay, Peru and Mexico had practical and theoretical sessions at the archaeological site of Tula and in Mexico City.
The first week was devoted to a detailed observation of case-studies at Tula, where participants applied the Objective Visual Observation (OVO) method. During the second week, they used a variety of documentation methods. The last week was devoted to additional archival and laboratory research, in order to synthesize all of the information and prepare a diagnosis and condition assessment of the case studies. Participants also shared their own experiences by presenting case studies from their home countries.
