This paper reports experiences from an art-science project set up in an educational context as well as in the tradition of placing artists in labs. It documents artists’ and scientists’ imaginations of their encounter and analyses them drawing on the concepts of “boundary object” and “boundary work”. Conceptually, the paper argues to broaden the idea of boundary objects to include inhibitory boundary objects that hinder rather than facilitate communication across boundaries. This focus on failures to link social worlds brings the boundary object concept closer to Gieryn’s boundary work and allows for a co-application of the two concepts in the analysis of cross-boundary communication. Empirically, the paper provides an in-depth ethnographic description of an art-science project as a resource for future practice. In conclusion, the art-science encounter included meeting points as well as multiple levels of boundary work which engaged the artists in a different way than as illustrators of scientific representations of climate change. The closer they got to the research practice the more the public and policy construct of climate change disappeared. Rather than political activism, the approach triggered explorations of the scientific context, including affirmative as well as critical re-imaginations of research practices. Artists and scientists acted as publics for one another, as resources to draw on for reflection and self-identification. But instead of cutting back or renegotiating standards of one’s own practice, especially the artists engaged in boundary work creating space to produce a piece of art according to their own criteria of quality and relevance.
