Bauxite

I. The Metaphysical Reading

How the stone has been held.

Bauxite is regarded as a plain and honest stone of place, carried for practitioners rebuilding their relationship with the ground beneath a particular home or region. Its association with slow tropical weathering is read as a metaphor for the long work of settling into a life.

II. The Scientific Reading

What the lattice actually does.

Bauxite is not a single mineral but a residual rock composed mainly of the aluminium hydroxides gibbsite, boehmite and diaspore, together with iron and titanium oxides that give it its rust colour. It forms in humid tropical climates when prolonged weathering leaches silica and other soluble elements from parent rock, leaving a pisolitic mass of aluminium-rich nodules. Bauxite is the world's principal ore of aluminium, mined at enormous scale from lateritic plateaus in Australia, Guinea and Brazil.
