Oaxaca Indigo Dye Workshop Delights Penland School of Crafts Visitors

Penland2013_1-45Dyeing with the natural color of indigo was a highlight of the Penland School of Crafts textile workshop tour of Oaxaca in early November.  I brought this wonderful group  of women — all first-time visitors to Oaxaca — for a workshop with Eric Chavez Santiago and his parents at their family home in Teotitlan del Valle.

Indigo is a plant that grows wild on the southern Pacific coast of Oaxaca in the village of Santiago Niltepec.  Before we rolled up our sleeves to immerse our hands and white cloth into the dye pot, Eric explained the process of how indigo is processed here by hand to get the intense color that you see in the photos.

After Eric demonstrates how to twist, tie, bundle, fold, clip, band, and otherwise manipulate a white piece of cotton to get a pattern, each person takes their cloth and starts their own project.  Some choose marbles that are held by rubber bands.  Others fold the cloth like a sandwich of triangles. Some combine the two.

It’s a surprise when we unroll them from the styrofoam tube.  Every resulting piece is unique and beautiful.  Perfect for a scarf or wall-hanging.

I cannot say enough about Eric and his family, what an education and experience. I feel like I have new friends in Mexico. The personal contact and sharing make this such a rich and deep experience, not just learning a skill but really feeling the history of the culture and being charged by the experience. – Barbara Benisch

During the workshop, Federico Chavez Sosa and Dolores Santiago Arrellanas give us a break and show us the process for tapestry weaving with a thorough demonstration.  The family only uses natural dyes to produce the rugs they weave.

We have two spaces left for a 3-day natural dye workshop in January, several spaces open for a 4-day tapestry weaving workshop that immediately follows.

We develop customized programs like the one for Penland for arts organizations.  Contact us to learn more.

Indigo Blue, Color of Kings: Oaxaca Natural Dye Workshop

If you are looking for hands-on instruction, a cultural immersion into natural dyes of Oaxaca, and would love to have an experience learning from the Museo Textil de Oaxaca’s director of education Eric Chavez Santiago, please contact me.  We organize programs for museums, textile guilds, fiber artists, designers and anyone wanting to know more about hand-dyeing with natural materials.

Here are some of the topics Eric talked about during the second day of a workshop we organized for Sydney, Australia’s Walter G & Company that focused on indigo dye recipes and using indigo for over-dyeing:

DyeWorkshop-34 DyeWorkshop-15Royals around the world coveted indigo as a symbol of their wealth, power and prestige.  When we think of the color royal blue, what comes to mind is an intense, deep color that saturates the fabric and draws attention to the person wearing it.  Indigo was used 6,000 years ago in Egypt, sought after by the Pharaohs who procured it from traders who traveled the tropical belt of Africa.

 DyeWorkshop-30  DyeWorkshop-31

Indigo is mystical, says Eric.  In Africa, dancers pray for an abundant indigo harvest to give them an abundant life.  In Puebla, Mexico, there is a traditional story that warns pregnant women not to approach an indigo dye bath.  If they do, the power of the color will disappear.  But indigo is a chemical process, says Eric, straightforward and scientific.

DyeWorkshop-27 DyeWorkshop-22

Today from Oaxaca, Mexico, to Africa, to India, to El Salvador, to South Carolina, USA, over 40 different indigo plant species, some of them wild and native to each region, are cultivated for dye material, explains Eric. In Oaxaca state, the wild bush grows along the Pacific coast, is cultivated, fermented, dried into blocks, and sold to weavers and dyers, who grind it into a fine powder for use on protein fibers such as wool and silk, or on plant fibers such as cotton.  Our workshop focuses only on dyeing wool, since cotton takes much longer.

DyeWorkshop-23 DyeWorkshop-24

This year, in 2012, Oaxaca had the largest harvest of indigo ever.  Over 400 pounds of dried leaves were picked.  Oaxaca’s indigo produces one of the most powerful, intense colors in the world, along with the indigo of San Salvador.  The color from India and Africa pale in comparison. This is good for local weavers who are turning to the use of indigo for its color-fast results and organic properties that ensure environmental sustainability.

DyeWorkshop-28 DyeWorkshop-12

During this second day, we used an indigo recipe developed by French chemist-dyer Michel Garcia.  Eric has studied with Michel Garcia and uses his fructose-based recipe along with hydrogenated lime.  The fructose reduces the oxygen in the water, stabilizes the water, and suspends the indigo to yield a more uniform, intense color.  One only needs to stir gently with a wooden stick or fingers!

DyeWorkshop-11 DyeWorkshop-14

To pulverize the rock-hard indigo, ancient dyers used a metate and mano de metate.  Today, Eric uses a coffee grinder — one for blue indigo, another for red cochineal.  He dissolves a bit of the indigo in a small sealed jar of water filled with marbles, and shakes it well.

DyeWorkshop-41

There are many indigo dye recipes available on the Internet along with recommendations for making dye baths, so we are not going into that here.

DyeWorkshop-37 DyeWorkshop-13

During the two days, we dyed a range of primary reds and yellows using cochineal and pericone.  On day two, over dyeing these colors with indigo, we were able to make a broader range of greens, oranges, browns and blacks.  All in all, the two days resulted in over 20 stunning colors — all color-fast, durable and natural.

DyeWorkshop-42

We are happy to organize customized workshops and plan a series of open-to-anyone-interested two-day workshops starting this summer, just like we did for Walter G & Company principals Lauren Bennett and Genevieve Fennel with friends Lara Zilibowitz and Tempe McMinn.

Oaxaca Natural Dye Workshop: A Gift of Color From Mother Nature

Several months ago Australian home furnishings designer Lauren Bennett contacted me about taking a natural dye workshop in Oaxaca with her business partner Genevieve Fennel.  Lifelong friends with a passion for textiles, they started the Sydney-based company Walter G & Co. almost two years ago, importing textiles from India to market a home decor line for resale to designers and shops.  In India they work primarily with Rajasthan artisans who use indigo, saffron and madder dye.  They wanted to learn more about natural dyeing in Oaxaca with indigo, cochineal, and wild marigold, including how to ensure color stability.  Their goal was to compare techniques and processes between the two regions, become more informed, and better direct their textile business.

In Oaxaca, there are few more knowledgeable about natural dye chemistry and applications than Eric Chavez Santiago.  As director of education at the Museo Textil de Oaxaca, Eric works with indigenous artisans to preserve the textile traditions of the state.  He  comes from a family of Zapotec weavers in Teotitlan del Valle, and early in his career developed over 100 recipes for cochineal that his father Federico Chavez Santiago uses to dye the rugs he weaves and sells at Galeria Fe y Lola in Oaxaca city.

Lauren and Genevieve arrived this week along with two friends, Lara Zilibowitz and Tempe McMinn.  With Eric as their dye master, they rolled up their sleeves and jumped into washing, dyeing and over-dyeing wool skeins over the two days we were together.

DyeWorkshop-6 DyeWorkshop-3 c Norma Hawthorne

Eric’s teaching style is both didactic and hands-on.  He carefully explained the history of dyeing in Oaxaca, the differences between dyeing with protein (animal) and plant fibers, types of mordant, issues of toxicity, and small batch vs. production work.  He showed examples of cochineal recipes he developed that are tagged with proportions.  The two-day workshop focused only on dyeing protein fibers like wool, alpaca and silk.

DyeWorkshop-2 c Norma Hawthorne

During the first day of the two-day program, we made a 10%, 20% and 70% cochineal dye bath and then did the same for the wild marigold, which is called pericone here.  You’ll see more of day two of the workshop when we made a indigo dye bath and our blue hands in a later post!

Eric explained how the pH of the dye bath and the temperature of the water are essential for a successful result.  He also demonstrated how the color of the wool  influences results.  White, beige, gray and brown wool will determine the ultimate color of the fiber when it takes the dye.  Eric shared his recipes and we were on our way dyeing skeins that he had mordanted in preparation. DyeWorkshop-10 c Norma Hawthorne DyeWorkshop-18 c Norma Hawthorne

Lauren, Genevieve, Lara and Tempe all said that Eric’s explanations and demonstrations are easy to understand and they loved being able to fully participate — hands-on.  Plus, they said, he speaks great English, so the learning experience was wonderful.  Eric offers a step-by-step approach with intermittent review of concepts so no one is left behind if the chemistry becomes a bit complicated.  He loves sharing Oaxaca’s dyeing traditions and wants people to be as excited about natural dyeing as he is.

Stay tuned!  We are planning more dye workshops. If you want a customized workshop especially for a group of people, please let me know and we will try to make it happen!

Cochineal is native to Oaxaca and the state of Puebla.  It was tribute paid by the Zapotecs to the Aztecs.  After the conquest, the Spanish took it to Peru, which is now the largest producer of cochineal.  Cochineal is colorfast if mordanted properly.  It is very precious and costs about 1,500 pesos for a kilogram of dried bugs — that’s about $60 USD a pound.

Yellow is the least stable color to achieve, says Eric.  Without proper mordanting, it can degrade the fibers and fade. Wild marigold, native to Oaxaca, yields a strong, stable color.  Today, we worked with cochineal and pericone to get about 20 different shades based on the wool color, strength of the dye bath, and the process called overdyeing.

Indigo Dye Workshop: It’s Called Shibori, Not Tie Dye

Actually, using resist dye technique using indigo to create patterns and designs on cotton is called shibori, tritik, amarra or plangi(depending upon country of origin).  It’s not the hippie dippie 60’s tie dye that’s been reincarnated on beach blanket bingo T-shirts.  It’s high fashion wearable art.  Not long ago, I saw an Eileen Fisher designer label Made in Japan shibori design on a finely woven cotton scarf dyed with indigo at a Nordstrom selling for over $100USD.  The technique is universal.

Norma's Indigo Dyed Shibori Napkins -- A Gift for Jacob and Michelle

As frequently as once per month, Eric Chavez Santiago teaches a hands-on indigo dye workshop for people of all ages at the Museo Textil de Oaxaca.  At a recent workshop, a mother, father and baby sister accompanied a six-year-old who made a fish design on a white cotton T-shirt.  Dad was right by his side and the learning was a fun family adventure.  Other participants included local artists, university design program students, and visiting tourists.

  

Indigo can be used to dye cotton, wool, alpaca, silk, linen and the fiber of the agave plant.  Some women in Oaxaca villages even use indigo to dye their hair.  Dyeing with indigo is all about chemistry.  Cellulose fibers such linen, cotton and agave absorb less indigo to get an intense color than do protein fibers of silk and wool.  Said another way, it takes less indigo to dye cotton than wool.  That’s why, we are using 100% cotton for the workshop.  Polyester blends just won’t work because indigo saturates only the surface of the fiber, not it’s core.

Look for Felted Fashion Oaxaca Style, coming in February 2013.                                                                                It includes dyeing wool roving, silk, and cotton with natural materials and  making your fabric into luxurious scarves, blouses, wraps.   Contact me to get on the mailing list for complete course description.  Instructors are clothing designer Jessica de Haas, Vancouver, B.C., and Eric Chavez Santiago, Oaxaca, Mexico.  Limited to 8 participants.

 

The process is fairly simple.  First, we rinse the white fabric (I dyed white, handwoven cotton napkins from the Amuzgo tribe) in clear water to soften it.  Then, we squeeze out all the moisture and make our design.

1. To make the shibori design, you can make accordian folds and then tie this together with rubber bands or with string.   You can drape cloth over marbles or beans, securing them with string or a rubber band.  You can whirl the fabric and then tie it with string or rubber bands.

 

2. To make the tritik design, you use a needle and thread to create a very specific pattern, folding the cloth and then sewing through it.

 

3. It probably takes about an hour to make the design.  Tie a lead string onto your fabric so you can easily fish it out of the water.

4.  Dip the folded and/or sewn fabric into the dye pot for 20 minutes.  Be careful to immerse it gently into the solution.  Do not stir or disturb in any way.  Pull the piece out of the dye pot with the lead string.

5.  Hang on a line from the string until the fabric changes from green-yellow to blue, for 15-20 minutes.

  

6.  Repeat two more times.

7.  Remove the rubber bands or thread.

8.  Rinse well in water.  Then, dip in vinegar water for 5 minutes to set the dye, soften the fabric and remove any of the alkaline residual and garlicky odor

9.  Let hang to dry.

  

Making Indigo Dye in Santiago Niltepec, Oaxaca

The market for organic indigo dye is making a come-back in Oaxaca as more textile artists and weavers are choosing to work with the natural plant material.  Today, the state of Oaxaca produces about 100 kilograms of añil or indigo each year.  Up until about three years ago, the indigo dye making process had almost died out in Oaxaca.

 

To stimulate the economic development of indigo as a crop, the state government has made investments to help the producers develop new markets.  The Museo Textil de Oaxaca gift shop sells small bags of indigo along with “how to” DVD’s and recipes. I learned this and a lot more during the indigo dye workshop I participated in at the Museo Textil de Oaxaca, where about 15 people gathered to learn shibori and tritik dye techniques using indigo.

 

 

 

 

 

 

The people in Santiago Niltepec, on the coast of Oaxaca near Juchitan on the Isthmus of Tehuantepec, pick the wild plant, chop it — stems and leaves — and put it in a fermentation bath for at least twelve hours (sometimes as much as thirty-six hours) to prepare the dye.  Each family has its own recipe for making the indigo paste.  Most use rocks to keep the plants submerged below the water to make sure that they oxidize completely and yield the deepest color.

The process is ancient, thousands of years old.  The plant material decomposes and collects at the bottom of the large vats as a thick paste.  It’s then strained to separate any sediment.  The result is a highly saturated, concentrated product.  It takes about 200 kg of plants to produce 1 kg of indigo dye.  It is then dried and becomes rock-hard.  To then use it, it must be pulverized into a fine powder.  Traditionalists in Oaxaca use a metate or mortar and pestle.  Others take the faster route by using an electric coffee grinder.

Indigo can’t be dissolved in pure water.  It has to be dissolved in a highly alkaline solution with a 10-11 pH, and free of oxygen.  Eric Chavez Santiago, director of education at the Museo Textil de Oaxaca, told us that there are several ways to manipulate the chemistry by using either sodium hydrosulfide (highly caustic) or the more organic fructose crystalline.  French botanist and dyer Michel Garcia is now experimenting with using mango skins and fructose successfully.

Eric says it is important to be patient when dyeing with indigo.  You can use the dye within thirty minutes after preparing it, but it often takes three or four days of fermentation to get the deepest shades of blue.

During the workshop, we dipped our white cotton material at least twice for 20 minutes each time, to intensify the color.  Some people even dye their hair with indigo!
