Salt
An Indispensable Mineral
The soup has no taste at all today – why? Ah – there is no salt in the soup! It is the salt that gives real flavour to the food. Many things we eat contain salt. Salt is part of our lives like the air we breathe or the water we drink. We need it to be able to survive and grow. Without salt, life on earth would not have evolved. Without salt, we humans would not exist. Without salt we could not live – but if we regularly eat too much salt, it will be detrimental to our health and may even be fatal. We live off and with the earth – and salts are important components of the earth.

Ceramic
Ceramics are indispensable in our everyday lives. We eat from ceramic plates, drink from ceramic cups, use tiled ceramic bathrooms. But how is ceramic manufactured? The film reveals the secrets of this fascinating material! We get to know more about the beginnings of ceramic in the Old World of Egypt and Mesopotamia, about Greece, China and Rome. We gain interesting insights into the valuable earthenware and are also shown the exquisite further development of the "white gold". Today this versatile material is irreplaceable in industry, too. Whether in space or as an easily compatible substitute in medicine, ceramic is applied in many places.
