Lime burning and slaking

The limestone rocks are first carefully layered in the kiln. After an initial heating-up phase the top of the kiln is covered with clay in order to conserve the heat. The kiln temperature is then increased to a white-hot level of approximately 1000°C. After burning, the lime is "slaked" by pouring water over it.
