The murky ochre liquid that spills through temporary sediment storage (in a plastic tank which will inevitably leak, melting in cubes, condensing on slumped glass) is collected from the drainage of a disused coal mine that runs onto a Northumberland beach through to the ocean. As the tide changes each day, pools of the ochre sediment merge with salty currents in ever varying dilutions and configurations, sedimenting on any organic or waste material it finds on the way. Although the toxic levels of metals in ochres themselves pose a risk to aquatic life, this sediment can also act as a remediation material for other contaminants such as Selenium, which is at particularly high levels in Northumberland coal. A semi-metal trace element that is usually hard to separate from the sulphides or organic matter it is fixed with, Selenium is used in e-tech for solar cells and in nanotechnology for anti-inflammation and anti-infection treatments. In this acidic stream, it becomes unusually fluid until it is bound with the fine-powdered ochre sediment. A toxic element of historic extraction becomes commodity and another potential cycle of extraction begins.
