On October 12-13, Det dolda will be travelling to the world-renowned glass blowing facilities at Kosta Boda to attempt to get some basic knowledge and notion about how glass, as a material, could be used for the production of masks. Tracing the collaborative learning process through auto-ethnographic, critical and performative writing, alongside photo documentation, the process will provide the materials for a performance based paper at Nordcode and the Swedish Research Council.
