The two Finnish glass artists Jukka Isolta and Jan Torstensson have opted for upcycling processes in glass as the basis of their design concepts. Both use waste glass as material: Isolta works with “cold” processing, in other words techniques such as polishing, cutting and sand-blasting; in contrast, Torstensson uses waste glass formed while it is hot, although not melted. The creative solutions produced by the two designers is on show in the exhibition by the WAGNER:WERK Museum, which was established in cooperation with the Finnish Glass Museum in Riihimäki (on show until 9 Nov.).
