Description
- Madder (Rubia tinctorum) makes a red-orange dye. At higher temperatures, the dye turns brown.
- The madder dye plant used to be widely cultivated in Zeeland (The Netherlands) to extract the coloring components alizarin and purpurine from the roots.
- The roots are not used fresh, but only after prolonged drying.
- Tip: For more intense colors, grind the madder and/or let it soak for at least 4-5 days.
