I. The Metaphysical Reading

How the stone has been held.

Crocoite is worked with as a stone of creative ignition, kept nearby during studio starts, first drafts and the moment a private project first meets a public room. Practitioners hold it as a reminder that some colours are so bright they must be earned.

II. The Scientific Reading

What the lattice actually does.

Crocoite is a lead chromate whose discovery in the eighteenth century led to the isolation of the element chromium — its name means 'saffron' in Greek. The finest specimens come from the Dundas mineral field in Tasmania, where slender orange-red prisms form radiating sprays in oxidised lead-zinc veins. It contains lead and should be handled dry and stored away from food surfaces.
