casting as a manufacturing process is one of the primary moulding processes and is probably even the oldest moulding process. developed during prehistorical cultures, different types of casting have been known for thousands of years. sand casting is one of the most popular and simplest types of casting. it can be used for most metals to be cast, depending on the type of sand used for the moulds. the sand can as well be reused after little maintenance. the liquid metal is poured into a prepared mould. the cavity, into which the metal solidifies, has the desired shape. the foundry massard in kayl (www.fonderiemassard.lu), a small enterprise in the south of luxembourg, is still specialised in the execution of this technique. they supported and helped out with the concept and the building of a small furnace (“mini-cubilot” or “cubilino”) of the dkollektiv, an initiative launched by the artist misch feinen. during the action “neiegoss”, organised during the “fête des hauts-fourneaux” in esch-belval, luxembourg (first edition: 1st and 2nd of july 2017/ re-edited the 28th of october and the 7th and 8th of july 2018), the small furnace is made operational and people can observe the whole process. the reproduction of the same forms and the question of their uniqueness, as well as the big procedural challenges and the role of the individual worker within the set are topics to reflect upon. for this project, a group of people with different backgrounds grew together without any hierarchy and through a lot of commitment and constructive interaction. as i was already familiar with the process of melting and casting precious metals, i could bring in my skills for the making of the moulds.
