Madder Dye Cut or ground ~ Dye Colour a variety of reds including orange, browns, reds, brick red, blood red and fiery reds.
*Collected in the Wild of Iran
The color depends on a variety of conditions, like the soil the roots where grown, their age, the mineral content of the water used for dyeing, the temperature of the dye pot, and how much madder you use in relation to the fiber. Many dyers suggest mordanting the wool just with alum and not to use cream of tartar as well, but that is your own choice and why not try to experiment a bit? Like with any dyeing, you will need to soak the fiber overnight or for a few hours before adding them to the dye pot for both hot and cold dyeing. You can dye with madder either cold or with heat; some dyers use chalk to get better reds.
