At the first part of the research we can say that the furnace that we were looking for was found by the analysis of documents that gave us the clue of where can be located. Then the archaeology took part, our team PAPACSUM in the year 2018 made a field survey in the zone until the furnace was located. For being sure that we found the furnace that we were looking for the team proceed to measure and get the floor plan and the side face of the building. The information that we get from the measures was very important to the research because those plans were compared to the original plans of the furnace, made in the XVIII century, in order to get conclusions. The next step that we have to follow still combines archaeology and history. Archaeology, because is needed to dig inside and around the structure in order to find more elements to complete the original plans and understand the function of the structure, and history because by studying documents we can find out why the furnace was located there and not in another place. ABSTRACT OBJECTIVES In 1788 the Spanish Crown wanted to evaluate the mining industry from New Spain in order to start the implementation of new technologies, changes of domain and administration of the mines, and the creation of new foundries that would help the mining industry to have more efficiency in all the processes related to this activity. That's why the Crown brought from Europe german miners and mineralogists, of which we will refer our work to Francisco Fisher, because he was the responsible of making the studies for the Crown of the mining conditions in Michoacan he was commissioned to construct a copper smelting furnace that would held the new technology of Europe. This work is about a cooper smelting furnace that was found near Santa Clara del Cobre by our team PAPACSUM in the 2018's survey season. By comparing archaeological analysis and documents we show that this smelting furnace is the same that Franz Fisher constructed. Additionally we reconstruct digitally the smelting furnace starting from sizing the ruins of the site. Moreover, we want to answer why Francisco Fisher's technology didn't work in the region, because the copper workers of the area still use the prehispanic and early colonial technics.

The study of the slags was carried out through archaeometric analysis, using X-ray Fluorescence (XRF), Scanning Electron Microscope with Dispersive Energy X-ray Spectroscopy (SEM/EDS) and Optical Microscope (OM). This generated data that allowed us to explore the chaine operatoire and the technology related to the reduction processes implemented, which could characterize part of the reduction technology used in copper production in this context. The inferences drawn from this research enrich the knowledge about the site of Jicalán Viejo and about prehispanic and colonial metallurgy in Western Mexico. Future research is expected to provide a more complete picture of the changes and continuities that occurred in the tradition of prehispanic copper extraction.
