In Session #2 we investigated the soils and mineral resources of the region. The students went in search of specific places in the area and explored them by means of methodically diverse “site visits”. This resulted in precise mapping and depictions of the ephemeral, the permanent and the particular of the local soils, the history of the place and the people there. In the next step, with the collected soil samples and their properties, the students tested different technologies in a workshop – including compression moulding or extrusion – to construct the first temporary structures. Based on the research and exploration of temporary structures and constructions, they experimented with compositions, constructions and surfaces and tested effects, (in)stabilities and modularities.
