A Brittle Metallic Vellum

Here, on the surface of humically darkened and acidic  pools in a rare and  ancient marshland, Thursely Common, the microbiological world reveals itself.

On the surfaces of such  undisturbed and natural ponds, a fragile and iridescent film will form. Often dismissed as just pollution, these brittle layers are in fact entirely natural, and are formed by the activity of resident iron and manganese oxidising bacteria. The films are so thin, that they are able diffract light, so that they become visible, and so shimmer with the colours of the spectrum,  and indirectly display their own inherent beauty.
