Sappanwood is native to SE Asia and India and makes a rich, pinkish red when calcium carbonate is added to the dye bath. It is one of the “exotic” red wood dyes that was traded along the Silk Road and used by medieval dyers. When used from 50-100% wof, the color is a rich deep red on wool. The dyebath and the sawdust can be reused until exhausted, creating lighter shades.
We like to extract the color by simmering the dyestuff in water for an hour, then letting it soak overnight. The next day, strain out the sawdust and reserve, then use the soaking water as your dye bath. You may add more water to the dye bath to cover the mordanted fibers, then gradually bring to 160F and hold for 45 minutes.
If you want to create magenta and fuchsia tones, add 1-2% calcium carbonate (chalk) to the dye bath before adding the mordanted fibers.
