Complete source
Ordinary fictional maker table. Nia has a clean, blunt-edged folded foil card, a drawing of a copper wire inside a lamp, and a sealed clear display of two labelled rocks. The foil package says aluminium; the wire drawing says copper. Nia can see folds in the card. Neither package names a particular mine. F1 describes bauxite as a common ore used to make aluminium through industrial processing. F2 describes copper's use in electrical wiring. These are source facts, not tests Nia performed. Nia wants a little trail label for a visitor who asks, “Is this just something from a shop?” No visitor has replied yet.
