Description

Found in the Gran Chaco region of Argentina, Quebracho Rojo (Schinopsis quebracho-colorado) is a dense hardwood. The legendary Argentine barbecue uses it for fuel. However, it is also an important tannin for the leather industry as the heartwood contains between 20-30% tannin. Recently quebracho has been listed by winemaking suppliers as it is used to resist oxidation of red wines as well as impart flavor. Quebracho rojo extract is suitable for dyeing cellulose fibers and also performs well on silks and wool, and yields a lovely pinkish peach to brown rose color.  So try Quebracho rojo extract on wool with aluminum acetate as your mordant for a brightened color effect. When overdyed with indigo, it creates a deep steel gray-blue.

  • 50 grams of Quebracho Rojo extract will dye approximately 500 grams of fiber (1.1 pounds) to a dark shade

From our Feedback Friday series:

I’m in love with quebracho rojo but I’m having trouble getting darker shades with my hemp/ cotton blend. Any tips would be fantastic!! Thank you! I’m using aluminum acetate as my mordant.

Quebracho is actually considered a lighter tannin-based dye, so it does not have the tinctorial strength like other dyes such as lac or madder. It’s possible to use more – like 10-20% on the weight of goods, and if you decide to do that, make sure you have other goods that you can dye with the remaining bath as it will still hold a lot of color.

Quebracho rojo! I am using this for block printing with your thickener on cotton tea towels, what is the best way to set the design without bleeding?

If the color is migrating or bleeding, make sure the base fabric is damp, not sopping wet. Steam set using a bullet steamer or a canning kettle. Use paper between the layers of your steam bundle to avoid color transfer. This assumes that your cotton towel has been scoured and mordanted before printing.
