Blue Hands Special — Oaxaca Day of the Dead 2-Day Natural Dye Workshop

So, you are coming to Oaxaca for Day of the Dead!

Here is a chance to get beyond the sugar skulls and cemeteries, the masks and parades, and go deeper into the natural dye traditions of our wonderful region without leaving the city of Oaxaca.

Put your hands into the indigo dye bath. Watch them turn blue: A Day of the Dead Badge of Distinction.  (OK, you can wash it off with soap and water, if you want.)

Blue hands, mark of distinction!

Natural dyes have been used by indigenous people of Oaxaca to color wool, cotton and silk for centuries. It thrives today among a small group of local artisans dedicated to preserving cultural history.

About the Dye Studio

We hold the dye workshops on the rooftop terrace of a home located in the City of Oaxaca, only 10 minutes walking from the main square of the capital. The studio was founded by two artisans, wife and husband, who are committed to preserving natural dye traditions. The wife is a native of Oaxaca City. The husband is a fourth generation member of a family of weavers and dyers in Teotitlan del Valle, Oaxaca. Both are bilingual, speaking Spanish and English.

Acid and base chemistry for color changes in cochineal

For the last 12 years, the couple has focused on natural dyeing processes and traditions. Their experience includes researching local indigo and cochineal, collaborating with local and international dyers, experimenting with recipes and testing fastness of the colors on both protein (wool, silk) and cellulose fibers (cotton, linen, hemp).

Both have taught dye workshops in universities, cultural centers and museums in Mexico, the United States and Europe. Currently, the studio provides the service of dyeing fibers for local artisan weavers and teaching workshops.

Textile Fiestas of Mexico guide book by Sheri Brautigam, with a little help from Norma Schafer

It was early 2016 and I’d just returned from taking a group of textile travelers to Tenancingo de Degollado, Estado de Mexico, to study the ikat rebozos of the region.  Textile maven and friend Sheri Brautigam was in Oaxaca putting the final content and photos together for her upcoming book, Textile Fiestas of Mexico.

With A Little Help from My Friends in Mexico

When Sheri is in Oaxaca (her home is Santa Fe, NM), we like to hang out together.

ONE Space Open: Ikat Textile Study Tour to Tenancingo, Feb. 2-10, 2017

I took her with me and introduced her to the Feria del Carrizo (river reed basket fair) in San Juan Guelavia, Oaxaca, just across the road from where I live in Teotitlan del Valle. She loved it so much, she decided to include it in her book! At the end of January each year, it’s a special event that includes hand-woven river reed baskets, lampshades, fish traps, music and amazing food.

Sheri’s deadline was fast approaching. She wasn’t sure she could get back to Tenancingo to interview and photograph people, something I had well-documented. I suggested that perhaps I could produce that chapter for her.

I also suggested that she include a chapter on the natural dye wool textiles of Teotitlan del Valle, focusing on the process of using indigo, cochineal and other plants and minerals.

Sheri sent the suggestion to Karen Brock at Thrums Books, the co-publisher, and she agreed.

If you are traveling to Mexico for any reason, this is the book you want in hand to explore the rich textile culture. It includes how to get to the textile regions, what to look for, where to shop for the best, where to stay and eat.

Of course, if you want a personal, immediate experience, come with me!

The third and last day of the three-day Oaxaca Natural Dye Workshop brings together all the preparation of the first two days in a culminating extravaganza of rich, deep color.

The beauty of natural dyes: deep, rich color, a rainbow to weave with

The movement toward using natural dyes is taking hold around the world. It is an environmentally healthy process that is non-toxic and sustainable. Here in Oaxaca more weavers are using natural dyes for their beauty and because it’s what eco-minded textile lovers want.

Elsa shows the film about the small village on the southern coast of Oaxaca, Santiago Niltepec, where two families remain who preserve the ancient tradition of growing the indigo plant and making it into dye material.  All the indigo that Elsa uses is native to Oaxaca.

Cochineal gives us red, orange purple and pink depending on the color of the wool, the number of dips in the dye bath, and whether we use an acid or base to modify the color.

When cochineal is overdyed with indigo, the wool becomes deep purple or lavender or mauve, depending on the strength of the dye bath and the natural wool color.

Oaxaca Natural Dye Workshop Day 2: Cochineal Red and More

Taking this Oaxaca Natural Dye Workshop is a study in color creativity. On this second day of three, we prepare cochineal, the parasitic insect that lives on the prickly pear cactus paddle. The chemical interaction between the female bug and the cactus juice produces carminic acid.

This is the most intense and color-fast red in the natural world.

When the Spanish came to Oaxaca in 1521 they were amazed to see the deep red used to dye feathers and to paint codices, human bodies or plaster temple walls.

They called it grana cochineal, naming it a grain not an insect to disguise its origin. The Spanish kept cochineal a secret for hundreds of years, holding the world monopoly on its production and distribution. It was the third most valuable export commodity after gold and silver.

Today, natural carminic acid colors cosmetics such as lipstick, and foods and beverages like Campari, fruit juices, jello and even meat.

Cochineal is expensive, about $125 USD or 1,800 pesos for a kilo. It can’t be wasted. That’s why Elsa grinds her dried bugs that she buys from El Tlapanochestli Cochineal Farm. You can buy packages of dried bugs for dyeing at the Museo Textil de Oaxaca gift shop.

She grinds them to a very fine powder in a molcajete. This is a lava stone mortar and pestle. It must be very fine powder to dissolve completely in the dye bath. The finer the powder the less waste there will be.

There is so much preparation even before the dyeing process begins. It’s no wonder textiles made with natural dyes cost so much! First, there is the investment in stainless steel and enamel dye pots, much more expensive than iron or aluminum, but essential so the pot chemistry doesn’t change the dye color.

Then, you have to make your recipes. What color red do you want? Deep fuchsia, orange, hot pink, magenta? Your recipe will vary depending on color intensity. You may add more water, more lime juice (acid) or baking soda (neutral).

Next, you’ll wash your fiber in soapy water to open up the fibers to clean it and accept the mordant. You rinse the fibers several time to take out the soap and then hang it to dry.

You will leave the cleaned fiber (we used wool) in the mordant overnight. This helps the wool absorb the dye.

On this second day, with the wool ready, we prepare the cochineal and then select the white and grey skeins to dye.

The cochineal dye pot is ready at 90 degrees centigrade. It takes an hour to cook the skeins so they absorb the right amount of color. During this time, we prepare wild marigold, mahogany, brazil wood, and pomegranate. Most of these skeins will be over dyed on Day Three to yield 32 different colors.

It’s no wonder the Spanish loved this color! Red on white and grey wool.

I write about natural dyes because Oaxaca has a long tradition of using colors derived from the natural world. I also want to encourage Oaxaca visitors to seek out and support artisans who work in natural dyes.

We determine color by weight of fiber (WOF) to amount of dye -- chemistry!

I hope readers will better understand the labor involved to make textiles using this technique. Yes, the textile will cost more. Perhaps you agree that its subtle beauty will be worth it.

Oaxaca Natural Dye Workshop, Day One: Prep to Make 32 Colors

For three days I am immersed in natural dyes with Elsa Sanchez Diaz who teaches our Oaxaca Natural Dye Workshops through Oaxaca Cultural Navigator. We make 32 different colors starting with a base of gray and white natural wool.

Indigo blue shirts are first made with natural manta cotton, then get four dye dips.

The natural plant and vegetable materials we dye with include palo de brazil (Brazilwood), nogal (walnut), cochineal (the red insect found on the prickly pear cactus paddle), caoba (mahogany bark), palo de aguila (alderwood bark),  palo de mora (fustic), pericone (wild marigold), granada (pomegranate) and añil (indigo).

Using a combination of base dyes and over-dyes, we make color variations of red, purple, orange, pink, yellow, green and blue.  Based on the wool color and number of dips into the dye bath, the color will be light or intense.

Rhiannon uses the mortar and pestle to grind cochineal to a fine powder. Elsa is happy with her results.

For the complete three-day workshop, the first day is mostly preparation of the materials, starting with making the skeins of yarn.  We learn about the history of natural dyes in Mexico, how the pre-Hispanic indigenous people used the dyes, and the symbols of the colors.

(We also offer One and Two-Day Dye Workshops)

To understand the entire dye process, Elsa says that it is important to begin with all the basic preparation steps. This is a time-consuming process and to be a natural dyer one must have patience. This is something we learn in Mexico daily.

On the street below the rooftop terrace where we work sheltered from the sun at the outdoor dye studio, I hear the sound of a high-pitched whistle. It’s the knife sharpener, Elsa says. Other street sounds signal the coming of the gas man and tortilla vendor.

Elsa says even when she uses the same recipes, the color will vary slightly each time.  This is handmade, after all! Color intensity depends on the pH of the water, the dryness, age or freshness of the plants and fruits, and the natural shade of the wool. This is chemistry, for sure.

Plus, when there are natural tannic acids in some materials like mahogany, indigo, fustic and pomegranate, the color is stronger.

Day One is a complete introduction to the two most frequently used dyes, pericone and pomegranate, and getting into the mindset of natural dyes, says our participant Rhiannon, a textile and jewelry designer from Canada. But, you don’t have to be experienced or a professional to learn … and have fun with color.
