Logwood Extract -Logwood (Haematoxylum campechianum) originates from and is naturalized throughout Central America. Logwood yields a rich, deep purple. Logwood by itself is not particularly lightfast, so keep from bright sunlight. With added iron, its lightfastness increases and the color darkens.
10 grams of Logwood extract will dye approximately 500g of fibre to a dark shade.
