Rust is the color of disappearance, the deintensification of metallic solidity. Seen in a different slant of light, rust produces a reintensification of color in the meeting of iron and oxygen, the proliferation of autumn in a congeries of breath, moisture, and steel. On the tongue rust acquires a taste: the bitterness of a disappearance, an evaporation that leaves behind the strange piquancy of material erosion.
