Abstract The thesis that the material origins of artefacts are essential to them is highly intuitive, but in a flexible version: it is not exact match of material origins that is intuitively essential, but approximate match. After an in‐depth exploration of the theoretical options open to accommodate the flexible version, the paper ends up favouring the inflexible one.
