100 % Natural Indigo | Origin: India | No synthetic additives

Harvested and processed in southern India, this true indigo powder delivers the deep, cool blues prized by dyers for centuries. Because indigo is an insoluble pigment (not a dye that bonds with a mordant), no mordant is required—just a reduced (oxygen-free) vat.

Why choose our indigo?

• Authentic & plant-based – Derived solely from Indigofera tinctoria leaves; never synthetic.
• Economical – ≈ 50 g colours 3–4 kg of wool to a strong mid-blue.
• Low-energy process – Vats work at 30 – 40 °C; no hard boiling.
• Versatile methods – Suitable for any indigo vat, be it fructose, mineral or bran-ferment vats, yeast vats, sig vats or quick hydros vats.
• Excellent colour-fastness – Outstanding on deeper shades, good on lighter blues.

Typical yield
• Pale sky blue – 1 g per 100 g fibre
• Medium denim – 5 g per 100 g fibre
• Deep navy – 12 g + per 100 g fibre (multiple dips)

Quick-start options

• Hydros Vat – Fast one-hour reduction (includes chemical oxygen remover).

Yeast Vat Recipe (500 g fibre)
9 l water · 110 g sugar · 50 g preservative-free dried yeast
30 g bicarbonate of soda · 40 g indigo (ground)

Logwood Dye

Dye Colour: Blue, Purple & Black | Collected in the Wild in Haiti

Logwood (Haematoxylum campechianum), also known as Bois de Campeche or Campeachy Wood, is a natural, pH-sensitive dye that originates from wood found in Central America. This versatile dye creates stunning blues, purples, and deep blacks on wool, cotton, and silk. While its colour fastness is considered poor by experienced dyers, Logwood is commonly used in combination with other dyes to achieve rich, deep blacks. Perfect for eco-conscious artists, Logwood is available as cut or ground bark for your dyeing projects.

Black Mallow Rose Flowers (Hollyhock)
Latin: Malvae arbor. Flor. tot. | Botanical: Alcea rosea L.

These vibrant Black Mallow Rose Flowers, also known as Hollyhocks, are perfect for eco-printing and natural dyeing projects. When used in eco-printing, they create stunning purple-blue to violet hues on fabric, with the rich tones evolving beautifully over time. Their colour fastness ranges from weak to medium, but can be enhanced with the proper mordants.

Eco-Printing Tips:

• For deeper, more intense black and purple hues, use an iron mordant.
• For general printing or dyeing, follow a standard mordant procedure for balanced results.
• Only the petals and flowers are utilized for printing and dyeing.

Durability:

Black Mallow Rose prints can retain their colours for years, but that very much depends on light exposure and washing. The anthocyanins in the petals provide some longevity, though fading may occur with prolonged sunlight or frequent washing.
