Waidmühle
Woad mills were used to process woad , a plant that was widely used to make blue dye before indigo began to be displaced in the 16th century . The last commercially used wood mill in Horse life in Thuringia stopped working in 1910.
Since woad processing was particularly widespread in Thuringia , the original woad mills can be found there today, for example in Erfurt on the Cyriaksburg citadel and in horse life. A reconstruction from original parts is in Rohrborn and a replica can be seen in front of a hotel in Bad Tennstedt . However, there was also a wood mill among the mills in the Hürth area near Cologne .
The counterpart to the woad mill is the madder mill . In it, red dye (madder) was ground, which was used to produce a red dye. The red dye was obtained from the root. The dried roots were ground into fine flour in madder mills (e.g. in Frankenthal , Haßloch , Iggelheim , Mußbach and Speyer ); the yield per hectare was 60 quintals .
