Projecte de recerca elaborat a partir d’una estada a la Universitat de Freiburg, Alemanya, entre setembre i desembre 2007 L'objectiu de l'estada ha estat aprofondir la recerca de l'impacte que va tenir el desenvolupament de la metal•lúrgia sobre l'especialització del treball, l'estructura territorial de les comunitats i la consolidació d'importants dissimetries socials i econòmiques, les quals van resultar en l'aparició de les primeres organitzacions polítiques de tipus estatal a determinades zones d'Europa. En particular, ens interessava investigar les dissimetries entre producció i consum, el nivell d'especialització social del treball i l'existència o no d'excedents econòmics. Així mateix, es va prestar atenció als nivells de convergència i divergència interregional definits a partir d'una lectura socioeconòmica de determinats patrons d'enterrament i de les relacions d'intercanvi i de comunicació. Tot considerant la informació disponible actualment per a Europa central i oriental, és innegable el paper central que va tenir la metal•lúrgia en els canvis socials i econòmics que es van produir entre mitjans del IV i el II mil•lenni abans de la nostra era.

The ceramic shell is a material mainly used for making foundry molds. This research demonstrates that ceramic shell can be used for making sculptures with exceptional definition in its finish. The research has identified a number of advantages of the material to meet the challenges of an artist during the making of a sculpture. The research has been developed in six stages: In the first stage data were collected from the chaff as the process material. This was the starting point for research. In the second stage, we have set the appropriate composition of the slurry, both in percentage and type of binder, and firing curve. To this end, we evaluated the application characteristics, thickness, drying, mechanical strength, the reduction coefficient and porosity. In the third stage it was observed that the husk is suitable for all types of materials acting as support. It was also found that the slurry can be used with various sculptural processes: modeling, molding using silicone or plaster mold, shuttering, with internal metal frame, and so on. In addition, we have established methods to repair and modify the husk by hand and power tools. In the fourth stage we have found ways to modify the surface of the husk with other minerals that affect the structure: introduction of filing of copper, bronze and iron in the slurry ceramics, different staining procedure in hot or cold, by enamel slip, and so on. In the fifth stage sculptures were made using the methods established in the previous stages, to verify this hypothesis. The sixth stage, which is annexed, contains a new method to process the ceramic shell as a mold in casting that emerged from the proven methods in the investigation.
