MYROBALAN CHEBULIC ~ a tannin used for (pre) mordanting cellulose (Cotton, Linen) Fibres. Recipe below.

ORIGN: India

Myrobalan is a very common tannin used in India and around Asia. It creates a plum-like fruit from various trees of the genus Terminalia, formerly used in medicine as a mild laxative and now used in the dyeing industry.

Myrobalan creates butter yellow on fabric, like most tannins. Tannin is important for mordanting cellulose fibres like cotton and linen. Alum alone is not a suitable mordant for cellulose fibres and its use will produce inferior colours.

Myrobalan can be used in print, over dye with indigo for teal, use as a stand alone colour or as a mordant.

***********************************************

Recipe Downloadable PDF for creating Greys and Charcoal 

Basic recipe for mordanting cellulose fibres:

A 2 step process, please read through the entire instructions first.

Step 1:

Ingredients:

10% Myrobalan (10% of the weight of fabric (w.o.f.))


1.Fill a plastic or stainless steel vessel with hot water (40-50 d. Celsius/100-120F) to a 30:1 ratio (water : fabric)

2. add tannin and stir until dissolved or evenly distributed

3. add fabric, immerse fully for 1-2 hours. The bath will cool down, which is totally fine. Stir occasionally.

4. use rubber gloves when removing fabric, squeeze fabric. Rinse very lightly or better spin it out using a centrifugal spinner or washing machine. Tannin is bound to the fibre only by affinity and can be removed if rinsed aggressively.

5. save mordant for future use.

6. don't let it dry before moving to the 2nd mordanting step.

Step 2:

Ingredients:
Alum 12% (w.o.f.) Dissolved in enough boiling water, cool.
Soda Ash 1.5% (w.o.f.) Dissolve in enough boiling water, cool.

1. Combine the two solutions while stirring. It will bubble, so make sure your vessel is big enough.

2. Bubbles will subside quickly and you should be left with a clear liquid. Add additional hot water as described above. Follow steps 3 - 5 from above.

3. Rinse the textile well, to make sure any unattached mordant is rinsed off.

4. The textile may be dyed immediately or dried for future use.


Tips:

*Too hot and the tannin will oxidize, which is fine, if you want a potentially darker colour. For overdyeing, it is best to keep the colour as light as possible.
** You can also use cold water instead of hot, but it will require a 12h soak at least.
***Any tannin can be used with this recipe, but for lighter results use Oak Gall or Tara.

Enjoy!

100% Natural Indigo (Indigofera tinctoria)

Traceable · Traditionally fermented · Origin: India · Approx. 35-42% indigotin

This is a high-quality, truly natural indigo, prepared in India from fresh leaves of Indigofera tinctoria using a traditional natural fermentation process. The indigo is supplied in powdered form and produces clear, stable blue shades ranging from very pale sky blues to deep, dark navies.

All batches are subject to analytical controls to verify their natural origin. This additional level of checking provides reassurance and traceability in a market where adulteration and partial synthesis have become increasingly common.

The main colouring component is indigotin, valued for its excellent lightfastness and wash fastness when dyed correctly.

Use in textile dyeing

Indigo is an insoluble pigment rather than a mordant dye. In order to dye fibre, it must first be reduced from its blue, oxidised state into a soluble yellow-green form. This reduced indigo penetrates the fibre and then re-oxidises on contact with air — the moment when the characteristic blue colour develops.

This indigo is suitable for a wide range of vat systems, including natural fermentation vats, fructose or sugar vats, lime-based mineral vats, bran vats, and quick vats using hydros or thiourea dioxide. Vats typically operate at 30–40 °C, making indigo dyeing a comparatively low-energy process.

It can also be combined with other natural dyes, such as yellows or reds, to create layered colours including greens, purples, and complex overdyes.

Typical usage guide

For pale sky blues, approximately 1 g of indigo per 100 g of fibre is sufficient.
Medium denim blues are usually achieved with around 5 g per 100 g of fibre.
Deep navy shades generally require 12 g or more per 100 g of fibre, built up through multiple dips.

Other uses

Beyond textile dyeing, this indigo can be used as a natural pigment for paint making, ink, decorative finishes, and woodwork. When used as a pigment, it should be well ground into the chosen binder or medium to ensure even colour development and to avoid visible particles.

The plant

Indigofera tinctoria is a small shrub traditionally cultivated for indigo production and is thought to have originated in India. The plant and its dye are mentioned in some of the earliest Sanskrit texts, and indigo was long known as “the queen of dyes” before the widespread adoption of synthetic indigo at the end of the nineteenth century. Other species of Indigofera have also been used historically as sources of natural indigo.

Storage and safety

Store in a cool, dry place, sealed against moisture. Avoid inhaling fine powder and wear a mask when handling. Gloves are recommended when working with lime, hydros, or iron additives.

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

Organic Ground, Cut, or Whole Hibiscus Flowers
Vibrant Pink & Purple Hues for Dyeing | Cultivated in Egypt

Hibiscus flowers are an excellent choice for natural dyeing, offering stunning shades from light purples to deep pinks and even greens, depending on the mordant used. Ground Hibiscus produces a lighter purple hue on wool, while cut or whole flowers yield more vibrant tones. This pH-sensitive dye is perfect for hobby dyers and children’s activities, as it offers interesting colour shifts - from green to purple to pink -  and an experimental approach to dyeing.

Dyeing Tips:
