For more than 300 years we have manufactured Makkum ceramics. This is not surprising, as clay is freely available in our area. We are also the only remaining company to produce original Delftware.
To do this we use locally-mined clay that is fired and coated with an in-house manufactured tin glaze. A second careful firing creates the characteristic colour and gloss that cannot be obtained using any other technique.
Clay is a material that is created by erosion and in its pure form contains a high percentage of the mineral kaolin. The more this sedimentary material is removed from its original location by rain, streams and rivers, the more the kaolin changes and is contaminated with other minerals. Earthenware differs from porcelain because the raw clay is furthest removed from its origins and is therefore the most ‘polluted’. The clay has far greater porosity and is baked at a temperature of only 1000 to 1050°C. This is in contrast to porcelain, which is baked at a higher temperature (1300 to 1450° C). Stoneware lies in between and is baked at around 1200°.
