Archaeometric analysis proposal for negative decoration

The main purpose of this text is to offer what could be a kind of road map within the possible archaeometric protocols to address the old problem posed by ceramics with negative decoration and the possible relationships that would have occurred between Western Mexico and South America. A perspective is also offered on what is negative from a technological point of view, according to ethnoarchaeological analyses, important since despite the great temporal distance that separates us from the makers of this ceramic decoration (possibly men and women) ethnoarchaeology. It provides clues to make better questions about the archaeological context.
