Orpiment: The Colour and the Hands — Lacuna

Alone at the desk after midnight, Lacuna writes down a name: orpiment. From the Latin auripigmentum—gold pigment. Even the name remembers what people wanted from it.

In a photograph, its orange-yellow crystals seem to hold a little daylight. Not gold, not a light of their own: arsenic bound with sulfur, taking this bright mineral form. The beauty and the danger are not separate ingredients that someone neglected to sort.

It formed in the relatively low-temperature workings of hydrothermal veins and hot springs, where mineral-bearing fluids could leave crystals behind. A quiet accumulation. Nothing in that golden surface announces the precautions it deserves.

For centuries, painters wanted its yellow. But making that yellow available to a brush meant handling a toxic mineral; grinding it could bring arsenic-bearing dust into the working day. A luminous passage on a painted surface could begin with danger at someone else's table.

Lacuna leaves a space before the last sentence.

It is easy to remember the colour and forget the hands that had to prepare it.
