MATERIAL DESCRIPTION

As an enigmatic hydrated iron phosphate, vivianite knows tidal places, estuaries, rhythmic coastal sediment infused with salts of the sea and an “unplaceable magical discomfort.”1 Prone to invisibility, blue ochre clings to places where excess phosphorus in water runoff seeks to bind with iron, and in anaerobic environments such as butchery pits, wastewater pipes, and peat bogs rich in organic matter, soluble iron, and phosphorus. When formed below ground, vivianite is usually white or colorless unless exposed to sunlight or air, where the mineral begins to rapidly turn, as if gasping, from pale to deep blue in a matter of hours or days. Referred to lovingly as a diva, vivianite transforms quickly upon contact with fingers, oils, lipids, heat, light, gases, spirits, ghosts, lost souls, and local gaps in the etheric fabric. Prone to deep transformations, vivianite will easily change to olive or dark green, as well as darker bruise-like colors, and may become lush matte black over time. Because of that mysterious process, blue ochre darkens into what is technically called meta-vivianite, which can be seen as misplaced black on Northwest Coast bentwood chests and shaman masks, traditionally stored in dark places, and if exposed to UV light, the deep blue becomes an unrecognizable shadow tone. A similar transformation can be found with Dutch master painters such as Vermeer and Rembrandt, whose pale “blew clay”2 paint today look moody and soil dim.
