(Also known as Coronillo, Quebracho Cornillo, Quebracho Chaqueño, Quebracho Colorado Santiagueño, Quebracho Macho, Quebracho Bolí)
Quebracho extract is one of the most tannin-rich dyestuffs available, with a tannin content of up to 76%. It dyes all natural fibres in shades of brown-red, pink, golden brown, and deep browns when used with alum. With an alkali shift, the colours move toward reds and pinks. It takes slightly better on cellulose than protein fibres, making it especially valuable for plant-based textiles.
Historical Note
The quebracho tree, native to South America, is famed not only for its dye potential but also for its extraordinary hardness (specific gravity 1.3–1.4, among the hardest known woods). Its extracts have long been used in both the tanning and dyeing industries. Traditionally, the wood was chipped and steamed in copper extractors to yield a concentrated dye liquor.
