To study the microstructure, segregation and material characteristics, four different mould materials will be used for casting: steel, terracotta, sandstone and sand. The steel mold is ready and was already tested for experiments on inverse segregation. The terracotta moulds are ready, but still need to be burnt… and the oven broke, so I will have to wait a bit to continue with these moulds. The sandstone moulds will be ready most likely by the end of the month – working sandstone is not that easy! …now I just need to prepare the wood box for the sand casting and I can start!
