II. The Scientific Reading
What the lattice actually does.
Orpiment is arsenic trisulphide, a soft, bright yellow mineral with a resinous to pearly lustre. It forms in low-temperature hydrothermal veins and volcanic fumaroles and is often associated with realgar. It is toxic and should be handled with care, never ingested or used in elixirs.
