Using walnut hulls for natural dyeing and ink making is a rewarding process that connects you with time-honored traditions of eco-friendly crafting. Below is a detailed guide on how to prepare and utilize walnut hulls in both their cut and powdered forms to achieve rich, lasting colors.
Ingredients & Materials Needed:
Walnut hulls (cuts or powder) – about 100 grams
Water – 1 liter
Large pot or dyeing vessel
Strainer or cheesecloth
Fabric or paper for dyeing/inking
Optional mordants (such as alum) for enhancing color fastness
Protective gloves (to avoid skin staining)
Step 1: Preparing the Dye Extract
Start by placing the walnut hulls in a large pot. Add approximately 1 liter of water for every 100 grams of hulls. Bring the mixture to a boil, then reduce to a simmer. Allow the hulls to simmer gently for 1 to 2 hours. This process extracts the tannins and pigments, releasing a dark brown liquid.
If you are using powdered hulls, the extraction time may be shorter (about 45 minutes to 1 hour) due to the increased surface area. Stir occasionally to prevent the powder from settling.
Step 2: Strain the Dye
Once the liquid has taken on a deep brown color and the hulls have softened, remove the pot from heat. Carefully strain the mixture through a fine mesh strainer or cheesecloth to remove solids. The remaining liquid is your walnut hull dye or ink base.
Step 3: Preparing Fabric or Ink
For fabric dyeing, pre-wash your textiles to remove any residues. If desired, pre-soak the fabric in a mordant solution (such as alum) to improve color adherence and longevity. Then immerse the fabric in the walnut hull dye bath. Let it soak for 1 to 3 hours, depending on the desired color intensity. Longer soaking results in darker hues.
For ink making, the walnut hull dye can be combined with other natural ingredients like gum arabic to create a consistent and smooth writing ink. Adjust the concentration of the dye and additives to achieve your preferred ink viscosity and tone.
Step 4: Drying and Finishing
After dyeing, rinse the fabric gently in cool water to remove excess dye. Hang to dry away from direct sunlight to preserve the rich brown color. If using as ink, store your walnut hull ink in a sealed container to maintain freshness.
Tips & Suggestions:
Wear gloves to avoid staining your hands.
Test dye on a small fabric swatch before full application.
Experiment with mordants and dyeing times to achieve unique shades.
Walnut hull dye works well with natural fibers such as cotton, wool, and silk.
Store unused dried hulls in a cool, dry place for future use.
