Onya McCausland @ Karsten Schubert

In 2014 Onya McCausland embarked on a project working with the Coal Authority to collect and recycle the natural ochres present in the waste water that flushes through defunct mines, a material that would otherwise be sent to landfill.

For 51º43 33.56 N 3º07 58.63 W, McCausland exhibits paintings that have been made using two of the five ochres her research brought to bear: Six Bells and Saltburn. Their colours are defined by the immediate geology and minerals present in the mines they originate from, giving each pigment unique properties and hues.
