Discover the fascinating world of thermal radiation!

Did you know that the colour of salts depends on their crystal structure – and that this crystal structure changes with temperature? At the Leibniz-IPHT, we make thermal radiation visible by heating salts. Thanks to the temperature-dependent changes in their crystal structure, the salts change colour, providing a striking demonstration of the effects of thermal radiation.

Come along, experience this exciting experiment first-hand and discover how science brings colour into play!
