About the Oer project
Within the OER project we collect iron sludge from different wetlands across Europe.
The project started in 2016 in a small village called Vessem, The Netherlands. Vessem is one of the many groundwater protections areas under the control of Brabant Water. A vulnerable area where the region’s tap water is sourced. The water is extracted from sources of dozens of meters deep, and is about thousands of years old. Most of the oxygen in the water is already disappeared, and metals like manganese and iron are dissolved. In order to make our water from the tap drinkable, it undergoes an extensive process of filtration.
One of the residues of this filtration is iron. This is a solid residual and can be characterized by its deep red colour. Kirstie van Noort and Lotte de Raadt worked together on a material research based upon iron sludge, harvested in Vessem, The Netherlands. The outcome are several clay bodies and glazes developed from the iron sludge applicable to ceramics.
