oer project

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 ceramics workshop

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.

Ceramics casting and coloring courses no. 1

The course will take one day

09.30- 10:00
Introduction to our studio with coffee and tea.

10:00 – 12.00u
In the morning you will learn how to use a plaster mold and cast your own porcelain cups, bowls and plates. We will provide 6 plaster molds per person and also ready to use porcelain clay, colored with pigments extracted from the water production facility. After 2 hours you will have 2 cups, 2 bowls and 2 plates, ready for the kiln! After casting all the objects we will learn you how to glaze biscuit fired cups, bowl and plates.

While we’re preparing the lunch you will start with sketching your color design for your set of tableware.

Between 12.00 and 13.00 there’s a lunchbreak and we will serve you some homemade vegetarian soup including coffee and/or tea. Feel free to bring your own sandwich!

13.00u – till you finished coloring and designing your pieces (the workshop is open till 16:30)
The afternoon will be all about coloring white biscuit fired porcelain. You are free to choose your own colors (we already developed the recipes) and mix them. By using very simple color techniques, such as ‘dipping’, spray paint and masking you will color 6 different objects.

After the workshop we will carefully glaze and fire all your items, ready for shipping or pick them up at the studio!

Ceramics casting and coloring courses no. 2

The course will take half a day

13:30- 14:00
Introduction to our studio and an inspiration talk about the Oer project. Including all different steps of developing the pigments and the clay body.

14:00 – 15:00u
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.

15:00 – till you finished coloring and designing your pieces (the workshop is open till 17:00)
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.
