摘要：The following article outlines the selection and use of analytical strategies for the
study and conservation of two hallucinogen tablets belonging to the Regional Museum
of Antofagasta, that were sent to the Archaeology Laboratory of the Centro Nacional de
Conservación y Restauración (CNCR). Based on the available bibliographical information,
and as a fi rst contextual approach to the pieces, a trans-disciplinary exploratory research
was carried out to characterize the components of the snuffi ng tablets. Four main
samples were defi ned: wood, fi ber of unspecifi ed origin, textiles and whitish powder.
The methodology used included optical microscopy, histological techniques, thin-layer
chromatography, IR spectroscopy, X-rays and micro-chemical analyses. The results indicate
the presence of alkaloids as well as plant and camelid fi bers. The origin of the wood used
to make the tablets could not be determined due to their poor conservation conditions.
This information is intended to contribute to the development of methodological bases
for the study of similar cases, making them available to the professional community for
eventual future researches.
