All dye recipes given below are per weight of fabric, on wool and silk.  For natural dyes to maintain their color-fastness and brightness, fabric or yarn (consisting of protein fibers) intended for dyeing must be simmered in Aluminum sulfate for a minimum of 1 hour. The detailed process of natural dyeing is presented in my workshops, several of which are offered throughout the year.

Indigo vat process on silk

Bio Indigo (Indigofera tinctoria) is among the oldest dyes to be used for textile dyeing and printing.  Indigo is a challenging dye because it is not soluble in water. To be dissolved, it must undergo a chemical change (reduction).  The primary use for indigo is as a dye for cotton yarn, which is mainly for the production of denim for blue jeans. On average, a pair of blue jean trousers requires 3 – 12 g of indigo. Small amounts are used for dyeing wool and silk.  There are two primary processes for vat dyeing;  a chemical process that uses soda ash and lye, and a completely natural fermentation vat.   See the Botanische Kleuren info page for more detailed instruction.

Cochineal extract

Cochineal  is one of the most concentrated dyes – a very small percentage is needed to dye deep shades of fuchsia to raspberry. Cochineal is pH sensitive, and it is possible to shift its color to scarlet with the addition of acid such as Cream of Tartar in the dyebath. It will give you reds with a tint of blue.  If you live in an area with hard water, Cochineal will dye its brightest and deepest shades if you mordant and dye with rain water. It is best to pour a little warm water over the extract to make a thin paste, then add boiling water until dissolved.

Crimson:  Cochineal 6%;   Pink: Cream of Tartar 6%, Cochineal 1.7

Cochineal instects: 25 g;   € 9,50

Cochineal extract: 25 g;   € 28,50

Lac extract

Lac (Laccifer lacca) responds well to alum mordants yielding rich shades of crimson to pink and purple to burgundy.   You will need a small amount of citric acid to use lac.  Although the color of lac is close to her sister, cochineal, lac has a more ruby tint, casting a warmer glow, especially to silk fabric.

Wine:  Lac 6%  

Lac  extract: 100 g;   € 21,00

Madder extract

Madder (Rubia tinctoria or rubia cordifulia) is a distinctive red with a yellow based tint.  It requires a long steep to completely dissolve in the dye bath.  Never raise the temperature while dying with Madder above 80 C.   Higher temperatures will brown out the color.   Madder extract and roots develop to their deepest red color in hard water.  The addition of 1-3% of calcium carbonate on the weight of the fiber will harden soft water to achieve red shade.  Pour a little warm water over the extract to make a thin paste then add hot water until it is dissolved.  If you add an acid to your dyebath, such as Cream of Tartar, you will create a soft orange with madder.

Madder extract:  50 g;   € 13,50

Brasiletto extract

Brasiletto (Haematoxylum campechianum) comes from  the heartwood of the logwood species.  It produces a bright red phenolic dye. This extract is very potent and very little is needed to produce a strong, beautiful bright red color.

Quebecho Red (Schinopsis quebracho-colorado) is harvested selectively from tree farms that participate in reforestation efforts, and our supplier has raised over half a million seedlings for replanting. Quebracho Red, heavy in tannin, can be used a base dye for overdyeing, or by itself.  It has a lovely rose tint on a light brown, soft and compatible with many other natural dye colors.

Quebracho Rose: 8-10% Quebracho Red   Mauve Rose:  3% Quebracho Red, left over dyebath of cochineal dyebath, or .5-1% cochineal extract (depending on the depth of mauve that you want).

Logwood Purple – Logwood (Haematoxylum campechianum) is a species of flowering in the legume family that is native to southern Mexico and northern Central America.  Logwood was the most widely used dye by the 19th century, providing the sober blacks of formal and mourning clothes.  Logwood’s lightfastness increases when you add iron.  Pure logwood extract produces a true purple to deep black purple.  Depending on the amount of iron that you use, you can create a logwood grey that can go all the way to a deep purple black.

Medium Purple:  .5% Logwood Purple  Dark Purple:  .65% Logwood Purple

Medium Grey:  .45% Logwood Purple, 1-2% Iron postbath   Dark Grey: .62% Logwood Purple, 1-2% Iron postbath
