BRAZILWOODS - This natural dye comes from various leguminous trees, including lima, sapan, peach wood, quebracho and palo de Brazil. Bark chips need to be soaked overnight and require about equal weight chips to weight of wool. Alum is the best mordant. Iron can be used as an after-mordant to deepen the colour. Some old dyers use Brazil wood to heighten the red of madder. It is not a very light-fast dye.Brazilwood natural dye gives crimsons, purples and pinks on premordanted yarns.
