California Natural Dyes – the ‘lost’ traditions

are being ‘rediscovered’

Historical documents (a few)

Some traditions handed down – now being shared

Looking to other groups – California & Baja CA

Trying to duplicate artifacts

How do you get those colors?

The dyeing process: 4 main steps

1. Prepare the material to be colored

2. Prepare the dye-bath

3. Dye the material

4. Complete the after-dye processing

Preparing the fiber/yarn: steps that help

the fiber take up the dye

Cleaning/ removing substances that prevent dyeing (grease; waxes; etc.) Washing

Stripping : heat, specific chemicals/substances, light exposure, other

Other physical preparations

Making the material more receptive to the dye, if needed

Wetting the material just prior to dyeing

What are mordants? Substances that improve uptake and/or retention of dye particles

From the French mordre, ‘to bite’. In the past, it was thought that a mordant helped the dye bite onto the fiber so that it would hold fast during washing.

Been used thousands of years

Two types: Chemical mordants; metallic salts

[alum; tin; iron, copper; chromium]

Plant mordants [tannins]

Not all dye/fiber combinations require a mordant

Let’s look at some of my favorite dye sources

© Project SOUND

Rabbitbush – Ericameria nauseosa

Rabbitbush: a natural dyer’s delight

© Project SOUND

Abundant

Easy to collect, use; can be stored

Good, durable dye

Lovely carotinoid pigment colors (yellows/gold/greens)

Nicely scented; non-toxic

Yellow-flowered Asteraceae: good starting dyes

Common in gardens

Need annual pruning

Can use both flowers, foliage

Easy to collect, use; can be stored

Good, durable dye

Lovely carotinoid pigment colors (yellows/gold/greens)

California goldenrod

the Goldenbushes

Ericameria species

Parts of plants used for dyes

Flowers/flower buds

Seedpods

Seeds

Leaves

Stems

Roots

Bark

Leaves can produce extraordinary colors

Island ironwood - Lyonothamnus floribundus

bark a traditional source of black dye

?? Can a dye be obtained from the fallen leaves

Challenge: leaves are tough & leathery

Why must dyes be ‘extracted’?

Location in plants Roots

Bark

Wood

Other interior tissues

Location in the cells Vacuole – water-soluble

pigments

Chromoplasts

Cell wall

Other

Have to do something to destroy well walls to release the pigment

Ways to create bright dyes (wool yarn)

1. Use a 10:1 ratio of dyestuff to wool (by weight)

2. Crush/cut dry thick, leathery leaves

3. Begin extraction with heat (20-30 minutes)

4. Let dye bath rest at least 2-3 days

5. Use multiple extractions to get multiple pigments

6. To dye, use 20-30 min heat + 2-4 days soak (or solar dyeing for longer)

Lyonothamnus leaves produce lovely

rusts and oranges

Taking advantage:

trimmings, etc.

Ponderosa pine (Pinus ponderosa)

Colorful inner bark

1-2” branches have thin outer bark

Needs time (year?) to separate bark easily

Stem and root bark pigments

Complex mix of ‘protective’ pigments:

Flavonoids – yellows

Anthocyanins – red/red-brown

Tannin – tan/brown (natural mordant)

Others

Pines

Junipers

Willows/Poplars (Salix/Populus)

Cherries (Prunus)

Apples & pears

Releasing pigments from tough sources

Dry the bark

Cut, pound or pulverize it

Let it soak in water for a few days to several weeks

Boil it for several hours

Let the dye bath sit for days to weeks – stirred or not

Strain out the plant material and use

Apply heat Hot/boiling water

Steam

Microwave

Apply force Pound/grind

Let microorganisms do the work – fermentation

Or a combination of the above

Tradition recipe for preparing

dye from a tree bark

Dye extraction requires patience

© Project SOUND

Extra time = better, more even color

© Project SOUND

Time to wash, rinse

& dry

“I don’t knit; what can I do with dyed yarn?”

Don’t you wish you had more/brighter

colors?

The natural dye colors are truly ‘California

Colors’

Why tradition/natural dye traditions are

important They provide sources of eco-friendly

dyes for: Fabrics, leather, wood, etc.

Foods

Medicines and cosmetics

They provide important models for medicine & engineering

They help us understand plants better; focus our attention on both botany and uses of plants

They are part of our human heritage

They inspire modern artists & craftspeople
