Lac Dye - A Beautiful Violet to Red to Brown Colour

Lac dye is a rich and versatile natural dye, known for its use in the iconic Tibetan Monks’ tunic. Unlike the vivid brightness of cochineal red, Lac produces a more mature, wine-like red tone that evolves from violet to red, and then into a warm brown.

What is Lac?
Lac is a resinous secretion produced by several species of lac insects, with the most commonly cultivated species being Kerria lacca. The cultivation process starts when a farmer attaches a brood lac stick, containing eggs ready to hatch, to a tree. As the insects hatch, they colonise the branches of the host trees and secrete the resin that forms the pigment. The branches are then harvested and processed into stick lac, which is crushed and sieved to remove impurities. The resulting product, seed lac, is further refined to produce shellac.

Colour fastness:
Good to excellent, ensuring lasting and vibrant hues.

Basic Recipe for Dyeing with Lac:

• 3-5% Lac (based on the weight of your material)
• Wool (no mordant required)
• 10-15% Alum (if using more than 5% Lac, or if preferred)

Instructions:

1. Dissolve the Lac in warm water and add it to your dye pot.
2. Immerse the wool (pre-wetted) into the dye bath, bringing it to a gentle simmer.
3. Allow the dye bath to simmer for one hour, ensuring the pigment thoroughly saturates the wool.
4. After an hour, turn off the heat and leave the wool to steep in the dye bath overnight.
5. Rinse the wool thoroughly and allow it to air dry.

One dye bath can be used to dye multiple skeins of yarn, making this an economical and efficient option for larger projects.

Additional Tip:
For enhanced colour depth, I would recommend a 20-minute vinegar soak after rinsing. This additional step enriches the dyed fibres and ensures a more vibrant finish.

Catechu Dye – Dye Colour: Brown and Beige | Botanical: Acacia catechu | Produced & Processed in India

Catechu, also known as Cutch, is a versatile natural dye that produces a beautiful range of brown and beige shades on cotton, silk, and wool fibres. This dye is composed of two components: catechu-tannic acid, which dissolves in cold water, and catechin, which requires hot water for extraction. Catechu is rich in tannins and will dye without the need for a mordant, though it can also benefit from one for brighter results. Some even suggest Catechu may help those with eczema – an added bonus for a naturally healing dye!

Colour Fastness: Good

Product Details:

• Dye Colour: Brown and Beige
• Perfect for: Cotton, silk, and wool fibres
• Mordant Optional: Alum for brighter colours, Iron for darker results

Basic Recipe:

1. Ingredients:
   • 200g wool (mordant optional)
   • 20g Catechu extract (made into paste with boiling water)
2. Instructions:
   • Add the Catechu paste to the dye pot with hot water and stir regularly.
   • Add the mordanted wool and simmer for 1 hour.
   • Leave the wool in the dye bath overnight for a deeper colour.
   • Let the wool oxidize before rinsing.

Note:

• Catechu is difficult to exhaust, meaning you can add more wool later for lighter tones.
• Mordanting the wool with Alum will give brighter results, but Catechu will still produce rich browns without it. For darker shades, use an Iron mordant.

Enjoy the versatility of Catechu dye and explore its potential for a wide range of beautiful brown and beige hues in your projects!

Plant Background:
Logwood (Haematoxylum campechianum) is a small to medium-sized tree native to the Bay of Campeche in the southeastern part of Mexico. It thrives in tropical climates and is primarily found in Central America, the West Indies, and parts of South America. The tree has a distinctive red wood, which is where it gets its name, and the wood itself is highly valued for its potent dyeing properties.

Historically, logwood was highly prized as a dye material and became one of the first commercially exploited resources of the New World. Following its introduction to Europe in the early 16th century, logwood was used to produce vibrant purple, blue, and black dyes. During the 17th century, England imposed a law that prohibited its use for a time to protect the domestic dyeing industry, but by the 18th century, it became widely used in Europe and other parts of the world for dyeing textiles, especially for black clothing, which was particularly fashionable in the 19th century.

The logwood tree has small, yellowish flowers and dense, dark green leaves, with the heartwood containing the dyeing agents. It can grow up to 20 metres in height and is a resilient plant, well-suited to tropical environments. While it is native to Central America, the logwood tree has been introduced and is now found in various tropical regions around the world, including the Caribbean and parts of Asia.
