Barberry Root Bark – Ground & Cut
Source: Berberis spp. (Barberry)

Barberry root bark is a traditional dye material valued for its high content of berberine, a potent plant alkaloid that yields clear, brilliant yellows on protein fibres. When modified with iron, it shifts to olive greens, making it a versatile addition to any natural dyer’s toolkit.

This listing includes ground root bark for quick extraction and cut bark for longer decoctions or soaking methods.

Barberry is known for its excellent light fastness, especially on wool and silk.

Main Components:

• Berberine (alkaloid)

• Alkaloid-rich tannins

Suggested Quantities (WOF):

• 20–30% for clear yellow

• With iron: 25–40% for olive tones

• Simmer gently for 60 minutes

Uses:

• Brilliant yellow dyeing on wool and silk

• Olive green shades with iron

• Layered plant dyeing with tannins and modifiers

• Historical dyeing and pigment preparation

The Plant: Barberry is a spiny shrub found across Europe and Asia. The root bark is its most dye-rich part, containing vibrant yellow berberine compounds also used in traditional medicine and inks.

Light Fastness:
High (excellent retention on protein fibres)

Form:
Ground and cut root bark

Tips:
Try layering with tannins like oak gall or sumac to deepen tone. Use on its own for luminous yellows, or with iron sulfate for olive greens.

FUSTIC HARDWOOD ~ Dyer's Mulberry, Old Fustic or Yellowwood
Dye Colour: Yellow and Green | Country of Collection: Unknown (Typically sourced from tropical regions) | Maclura tinctoria or Chlorophora tinctoria 

Fustic, introduced to Europe in the 16th century, is a classic natural dye that produces vibrant yellow tones and clear greens when overdyed with indigo. Sourced from the hardwood of the Chlorophora or Morus tinctoria tree, a member of the Mulberry family, Fustic is known for its strength, requiring only 50% of the dye by weight of fibre (W.D.F.). The wood chips used for dyeing are reusable, allowing for multiple dye baths.

Colour Fastness: Poor to Medium

Colour Outcomes by WOF Ratio:

• 50% WOF Dye (Fustic): Produces a bright, clear yellow hue.
• Overdye with Indigo: Results in a clear, vibrant green.
• With 3% Iron: Transforms the dye into an olive green tone.

Basic Recipe for Dyeing:

• Ingredients: 50% Fustic cut, 10% Alum
• Instructions:
  1. Mordant the yarn by dissolving Alum in hot water and adding the yarn. Let it steep overnight.
  2. Steep the Fustic woodchips in hot water overnight.
  3. The next day, rinse the mordanted yarn.
  4. Strain the Fustic dye and let it dry for an additional day.
  5. Add the mordanted yarn to the dye bath and heat to 85°C for 1 hour.
  6. Rinse and dry the yarn.
  7. Reusing Dye: If using the dye again, boil it for 45 minutes to deepen the yellow colour.

Unlock the potential of this traditional dye, whether you're looking for a rich yellow, earthy green, or vibrant hues when combined with other dyes like Indigo.

Horse Chestnut Bark – Cut

Source: Aesculus hippocastanum

Cut Horse Chestnut Bark is a lesser-known but valuable source of natural tannins, especially effective for cellulose fibre preparation, natural greys with iron, and historical dye practices. This bark contains condensed tannins, making it well suited for textile work on both plant and animal fibres.

Our bark is coarsely cut and ideal for slow dyeing, decoctions, or tannin-rich soaks. It can be used alone or combined with other tannins or metal salts for complex tones and improved mordant adhesion.

Main Components:

• Condensed tannins
• Flavonoids
• Saponins (minor)

Suggested Quantities (WOF – Weight of Fabric):

• 20–80% WOF for decoction or fibre soak
• Simmer for 1 hour or soak overnight
• Use hot or cool for varied tones

Uses:

• Pre-treatment of Cellulose Fibres – improves mordant take-up
• Iron Modification – yields soft greys and warm browns
• Natural Dyeing – use alone or as a tannin base
• Historical Dye Methods – suitable for re-enactment dyeing and archival processes

The Plant:

Horse chestnut is a deciduous tree native to southeastern Europe, now naturalised across Ireland and the UK. Its bark has long been used in folk medicine and traditional dyeing for its tannin content and gentle tones. When modified with iron, it reveals subtle grey-browns, ideal for grounding brighter botanical colours.

Light Fastness:

Medium to High (when used with a mordant)

Form:

• Coarse-cut bark
• Not water-soluble; requires simmering or soaking

🌿 Tip: Combine with iron sulphate for muted greys, or use as a base layer in multi-step dyeing on cellulose fibres.

Madder Dye – Cut or Ground
Rich Natural Reds for Dyeing | Wild-Harvested in Eastern Europe

Madder (Rubia tinctorum) is a renowned natural dye that produces a stunning range of reds—from warm oranges and rich brick reds to deep blood reds and fiery crimson tones. The final shade depends on multiple factors, including soil conditions, root age, mineral content of the water, dyeing temperature, and fibre-to-dye ratio.

Dyeing Tips:

• Mordanting: Avoid cream of tartar when mordanting cold. 
• Soaking: Pre-soak fibres for at least 12h-24h before dyeing.
• Dyeing Methods: Madder can be used in both hot and cold dye baths. Adding chalk can help achieve better reds.

Colour Fastness: Excellent – Madder is known for its durability and deep, lasting hues.

OAK GALL
Use: Cellulose Fibre Mordant | Harvested From: Aleppo Oak in Turkey | Also Known As: Oak Apple | Recipe: link below

Oak Gall, also known as Oak Apple, is harvested from the Aleppo Oak in Turkey and is a traditional mordant used for cellulose fibres. Due to its high tannin content, it is an effective mordant for preparing cellulose-based fabrics for natural dyeing. Unlike other tannin-based mordants, Oak Gall only stains the cellulose fibre a light beige, making it a preferred choice for delicate dyeing projects.

Key Features:

• High tannin content for cellulose mordanting
• Minimal staining cellulose fibres
• Available whole, cut, or ground

Function:
Oak Gall is used to prepare cellulose fibres for natural dyeing, helping the dye adhere to the fabric without leaving stains. Its high tannin content ensures vibrant and durable colours on cellulose fabrics like cotton, linen, and hemp. 

Storage & Usage:

• Available in whole, cut, or ground form.
• Store in a cool, dry place.

Perfect for natural dyers and textile artists working with cellulose fibre. Please see this recipe for mordanting cellulose with Gallotannin

• Cut or Whole Hibiscus: Use 75-100% of the dye weight relative to the fabric for deeper tones.
• pH Sensitivity: Hibiscus dye is pH-sensitive, meaning colour can shift, creating fun and unique results—perfect for those who enjoy experimenting.

Colour Fastness: Poor (colour may shift with pH changes)

Basic Hibiscus Dye Recipe:

1. Mordanting: Use Alum (10-15%) for dyeing wool.
2. Dye Ratio:
   • For mordanted fabric or yarn: Use 50-100% Hibiscus dye relative to the weight of the dry fibre.
3. Dyeing Process:
   • Soak Hibiscus flowers or powder in water and simmer.
   • Add mordanted fabric and simmer until the desired colour is achieved.

POMEGRANATE PEELS ~ CUT & GROUND ORGANIC ~ can be used as Tannin and as yellow dye

The pomegranate is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows between 5 and 10 m tall. The pomegranate originated in the region extending from Iran to northern India and has been cultivated since ancient times throughout the Mediterranean region.

 Colourfastness: good - excellent

Recipe:

For how to mordant your Cellulose fibres, please see my blog post 

 How to mordant linen and cotton fabrics successfully – AppleOak FibreWorks

If you are using protein fibres, a simple 10%Alum bath will do for mordanting, but protein fibres can also be dyed without a mordant when using Pomegranate peel due to its tannin content.

Once mordanted:

Add 100% pomegranate peel to 80degrees Celcius Water for one hour. (100% of the dry Weight of your Fibre/Fabric) If using powder, stir regularly or it will burn the bottom of your pan.

After an hour, switch of the heat and add the fabric/fibre. Leave to up to 3 days, until desired depth of colour. 

Wash, rinse, dry.

 Pomegranate Powder can also be used as a tannin and for printing when combined with Alum and Guar Gum.
