Within the OER project we harvest iron ore 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 oxidized iron, in Dutch called “Oer”. 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 pigments and glazes developed from the iron sludge applicable to ceramics during workshops hosted in their studio.
Oer tableware collection, workshop sale
Kirstie van Noort and Lotte de Raadt are hosting ceramics workshops at NulZes, Eindhoven, NL. During this workshop you will learn how to make and color your own porcelain tableware with the residue of a water production facility.
The course will take 3,5 hours
Morning course: 09:30 – 13:00
Afternoon course: 14:00 – 17:30
09:30 – 10:00 or 14:00- 14:30
Introduction to our studio and an inspiration talk about the Oer project. Including all different steps of developing the pigments and the clay body.
10:00 – 11:00 or 14:30 – 15:30u
Slip casting the developed clay body into plaster molds and learn how to use transparent glaze. We will provide 3 plaster molds per person and also ready to use porcelain clay, colored with pigments extracted from the iron ore slib. After 1 hour you will have 1 cup, 1 bowl and 1 plate, ready for the kiln! After casting the objects we will learn you how to glaze (with transparant glossy glaze) the inside of a cup, bowl and plate.
11:00 (till 13:00) or 15:30 (till 17:30) –
This part of the course will be all about coloring white biscuit fired porcelain. You are free to choose your own colors (we developed three recipes) and mix them. By using very simple color techniques, such as dipping, spray paint and masking you will color a set of 1 cup, 1 bowl and 1 plate.
After the course we will carefully glaze and fire all your items, ready for shipping or pick them up at the studio.
