Material Temporalities

Tour of conservation studios of NICAS
(The Netherlands Institute for Conservation+Art+Science+) followed by a workshop at the Rijksmuseum’s Atelier Building.

Wednesday, 6 November 2024

The Material Temporalities workshop was organized as part of Practicum Generale and introduced students to the conservation studios and laboratories of NICAS and the Atelier Building of the Rijksmuseum.

NICAS houses several restoration studios, each dedicated to the conservation of specific material categories.


The session emerged from a series of preparatory conversations between conservation researchers and members of the Materiality Research Group. A recurring theme was the notion of an artwork’s “material biography”: understanding what it is made of, how its materials can be investigated, and what this discloses about both its origin and afterlife. While conservation professionals often approach objects as historical evidence or time capsules, students were more attuned to the ethical dimensions of materials—especially in light of contemporary environmental crises and questions of social justice. This divergence of perspectives framed the workshop as a space to explore not only points of overlap, but also productive tensions between conservation and contemporary artistic practice.

The planning discussions also emphasized the speculative and political nature of preservation; conservation is never a neutral act, and always involves imagining possible futures for materials and deciding what will endure. From this perspective, the workshop aimed to connect institutional methods of conservation with the students’ own concerns as artists and designers—tracing how legacies are shaped by choices of preservation, omission, and transformation.

The program began with a guided tour through five specialized departments—plastics, modern art, imaging technologies, furniture, and textiles—offering rare insight into the material research that underpins conservation practices. Students encountered different approaches to analyzing and safeguarding artworks, from advanced scientific imaging to hands-on restoration processes.

Experiencing the conservation practices up close served as a foundation for the second part of the session, a workshop that foregrounded questions of preservation, process, and materiality. Together, the tour and workshop created a dialogue between institutional conservation methods and the students’ own artistic practices.

The day opened up an inquiry into the material biography of artworks: what they are made of, how their constituent materials are studied, and what such investigations reveal about an object’s cultural, historical, and environmental contexts. Conservation research emerged here not only as a technical practice but also as a broader philosophical reflection on the ephemerality of art, the ethics of preservation, and the ways in which materiality shapes artistic meaning across time.

In the workshop, students worked with materials they had brought—objects they considered worth preserving, whether found or self-made. Through a sequence of mapping exercises and collaborative reflections, they collectively traced speculative “orbits” around these materials, considering questions of provenance, touch, memory, and future trajectories. This method highlighted how preservation is always also a form of speculation, an imaginative act that projects possible futures for material things.

The discussions circled around a central question: what do we choose to preserve and what do we allow to disappear? By reflecting on their own material experimentations through the lens of conservation, students explored the tension between permanence and impermanence, authorship and process, visibility, and erasure.

By bridging the conservation studio and the classroom, Material Temporalities underscored that conservation practices—while often associated with safeguarding historical heritage—can also serve as a lens for contemporary artistic production and education. The session invited participants to consider their artistic legacies not only in terms of what endures, but also in relation to what is intentionally left to decay, vanish, or transform.
