This short article aims to provide a guide on how to approach the study of cultural heritage. It would also like to provide a relevant framework to promote dialogue between archaeologists, scientists, and conservation scientists. The objective is to furnish the widest possible picture of the type of analysis that can be used, of the results that are obtained from each of them and how this information can be useful to answer the questions that archaeologists, conservatives, and restorers ask themselves. Considering the short space available, we will not go into detail of the individual analyses.
