A by-product of tin ore processing, arsenic was extracted from the fumes emitted when crushed ore was burned by channelling the fumes through a labyrinth so that the arsenic crystallised on the walls and roof. Arsenic was exported to Scandinavia for use in clarifying glass, to America for control of the cotton boll weevil and to New Zealand for use in sheep dips.
