Wie hängen sie zusammen

Because genuine ultramarine is expensive and rare, artists started looking for alternatives early on. They found what they were looking for in the semi-precious stone azurite. Although colour pigment from azurite usually looks a little greenish in pictures, painters in the Middle Ages liked to use it because it was cheaper and more readily available than Afghan lapis lazuli. In the mineral showcase, you can see specimens from the Odenwald, from America, Africa and Asia.
