Walloon Oak (Quercus ithaburensis) The acorn caps from this tree native to the open forests of western Turkey, southern Italy, and southern part of Balkans are used. First a lightfast, yellow-brown color is achieved by boiling the wool with the acorn caps and leaving them soaking for several hours, followed by a rinse and dip in alkaline water (mixed with ashes). In order to make this turn black, a hot mordant bath with ferrous salts is used.

Botanical Extract Dyes can be sorted into three categories: Botanical Extract Dyes obtained from plants (indigo), those obtained from animals (cochineal), and those obtained from minerals (ocher). Creating and using plant-based-dyes is a wonderful way to gain an understanding of the biology and the chemistry at work in the plants around us.

Black dyes are possible when tannins combine with iron. However, this causes the corrosion of the wool. Use of ferrous mud and salts are less harmful. In addition, a black that is totally free of corrosion can be produced through a triple dyeing process. First the wool is dyed blue with indigo, followed by yellow from dyer’s weed, and finally dyed red with madder. Black seen in classical Persian carpets were made this way.
