INSTRUCTIONS FOR MORDANTING WOOL

  • Soak the wool in warm water and squeeze out excess water gently before adding to the mordant bath.
  • Use 15% of the weight of the yarn in Alum, dissolved in water. Eg: 100g of yarn = 15g Alum, 200g yarn =30g Alum etc
  • Add yarn to the mordant bath (with enough water for the yarn to move around easily) and gradually heat to around 80°C for 30 minutes and allow to cool slowly. Remove the wool and squeeze gently to remove excess liquid.
  • After mordanting, the wool can be simmered with natural dye materials. Simmer for approximately 30 minutes and turn off the heat. Do not boil.
  • Allow the yarn to cool slowly in the dyebath before removing the yarn.
  • Gently rinse out excess dye in clean water.
  • Safety first: Wear gloves and/or a mask while mordanting and natural dyeing in case you have sensitivity to any of the materials.
  • Experiment and keep records if you wish to attempt re-creating a colour.
  • Results will vary. That is the nature of nature :)
