1) What is Sorghum? Sorghum is a grain of the grass family used worldwide as a staple food. The non-edible cultivar that has most dye potential has rusty red marks on leaf bracts and blades.
Sorghum is not well known as a dye plant in Europe but it is used in Africa to dye leather for shoes as well as reeds and grasses for making mats.
2) What colours does Sorghum extract produce? Sorghum extract produces dark and light mauves, or rusty shades similar to madder.
First make a paste with 1 teaspoon (5 grams) sorghum extract and a small amount of warm water. Fill a saucepan with water and add the sorghum extract paste.
Add your pre-wetted mordanted fibre. Bring the dye bath to a gentle simmer and then keep at that temperature for 45 to 60 minutes. Sorghum extract tends to settle in the bottom of saucepan and needs stirring from time to time. Leave overnight to cool.
4) How much wool does Sorghum extract dye? 10 grams of Sorghum extract will dye one 100 gram hank of Blue-faced Leicester superwash wool mauve and another pale mauve. Colours vary with fibre and water.
