Indigo Dye: Organic, Natural synthetic & Complete synthetic

Indigo dye

Indigo is one of the oldest known natural dye used in ancient times to get natural blue extracted from Indigofera tinctoria plant leaves. Indian subcontinent was famous for its cultivation and used in dyeing traditional block printed clothes. It was one of the early known natural dye used in cold form by fermenting the indigo leaves or powder extracted from leaves through as certain process. 

In today's time natural indigo is used by very few dyers in organic form. To prepare a vat or dye pot any plastic drum or underground cemented tank is used. Size of the indigo vat depends upon the use and demand. Traditionally a pitcher is used to prepare a indigo vat. There are 3 variants of Indigo color is available in the market today.

Organic Natural Indigo

First we talk about the indigo used to ferment using organic process with natural ingredients. It is very important to use natural ingredients if any dyer is using natural indigo otherwise it is of no use to make a natural indigo vat. The natural ingredients used in preparing organic natural indigo vat are:

1. Water

2. Natural indigo cake or powder

Indigo cake

3. Cassia tora seeds (It attracts bacteria to fasten the fermenting process and extracting the color from indigo powder)

Cassia tora seeds

4. Lime (To make water alkaline and maintaining the ph value of the vat)

Lime in crystal form

5. Jaggery or sugar (A natural source of fructose works as a reducing agent)

Jaggery crystal

By mixing all the natural and organic ingredients in water with indigo powder a natural indigo vat get prepared.

Using all these natural and organic ingredients in preparing organic natural indigo vat requires 12 to 24 hours in activation. It also depends upon the weather and use of ingredients in proportion.

Natural Indigo with synthetic process

Natural indigo is prepared using natural indigo with synthetic chemical ingredients. Ingredients used in preparing natural chemical indigo vat are:

1. Natural indigo cake or powder

2. Lime

3. Caustic soda (Heavy chemical with toxic property)

4. Sodium hydrosulphite (Heavy chemical with toxic property)

If some dyer is using synthetic chemical ingredients as a reducing agent in preparing natural indigo then it is of no use because the natural herbal properties of indigo got nullified while using heavy synthetic chemical based reducing agents in preparing the vat. 

Why people use synthetic chemical ingredients in natural indigo?

1. It get activated within 30 minutes of preparing vat

2. Easy to maintain using chemical ingredients

3. Non- availability of cassia tora seeds or unaware about it

4. Sometimes no access to knowledge of preparing organic indigo vat

Synthetic Indigo 

Most of the indigo products available in the market are flooded with synthetic chemical indigo dyed products marketed as natural indigo dyed products. After introduction of synthetic version of indigo in the market every hand block printing cluster is using synthetic (chemical) indigo to dye the fabrics. 

Synthetic indigo vat get prepared using synthetic chemical ingredients only.

Ingredients used in preparing synthetic chemical indigo vat are:

1. Synthetic/chemical Indigo known as German indigo

2. Lime

3. Caustic soda (Heavy chemical with toxic property)

4. Sodium hydrosulphite (Heavy chemical with toxic property)

Why hand block printers or dyers use chemical indigo?

1. Pricing of synthetic chemical indigo is 2 to 3 times cheaper than natural indigo

2. Maintenance of chemical indigo vat is easy

3. Quick demand 

4. Lack of  knowledge about preparing natural organic indigo vat

Now the million dollar question is how to identify the difference in between synthetic chemical & natural indigo?

It is not easy to identify the difference of shades in between organic natural, natural chemical and chemical indigo dyed fabrics initially. It all depends upon the level of honesty and transparency of block printer, dyer or marketing company to mention it. 

Ajrakh in India: Two different school of thoughts

School of thoughts 

One of the most mystical colorful and oldest known technique of hand block printing is Ajrakh. We already discussed about the history and interesting story about Ajrakh in our previous blog "Ajrakh story" wrote more than an year ago. This blog will provide insight about two different school of thoughts based on the opinion of two different masters of Ajrakh on the evolution of Ajrakh. One modern thought developed in Gujarat about Ajrakh and another is from Barmer district of Rajasthan which stick to the old school of thought.

On the basis of my study and meeting with two legends of Ajrakh hand block printing National Awardee Shri Ranamalji Khatri from Barmer & Dr. Ismailji Khatri from Ajrakhpur, Gujarat during my PhD., I am sharing different perspectives of Ajrakh as told by them. It is important in recent times to have a clarity about different school of thoughts about Ajrakh.

One school of thought considers its Arabic meaning of Ajrakh as true other school of thought considers its literal meaning Ajrakh as a process.

While talking to the Ranamalji Khatri about Ajrakh he told the story of Ajrakh that in ancient times some 2500 years when Arab tradesman from Mesopotamia of today's Iraq visited Sindh region and saw traditional hand block printing for the first time where geometrical patterns created on the fabric with penetration of indigo blue in the base they instantly said "Oh, ye to ajrakh hain" (Oh, this is blue sky). In Arabic language "Ajrakh" means blue or sky. Since then it is known as Ajrakh to the world. They stick to the Arabic meaning of Ajrakh as it is used for geometrical pattern printed with red, black and white and dyed background with indigo blue gives the feeling of blue sky. For other color background they have different names such as "Nashpal" for green background. This approach what I can call "Orthodox" or Old school of thought.

In discussion with Dr. Ismailji Khatri; he considers "Ajrakh" as a process of doing hand block printing with a particular process of traditional importance and steps need to be followed. In his words Ajrakh means "Aaj hi rakh" (Keep it for a day), that means each and every step done in Ajrakh for a day only, one can not do next step of the process on the same day. One step need to be followed in a day only. So as per talk with the Dr. Ismailji Ajrakh is considered as a process with its literal meaning "Aaj hi rakh" (Keep it for a day). There is no restriction of color pattern without disturbing the traditional steps, use of natural color and process.

I consider this thought as Open or Modern school of thought.

But still I think more and more research and interaction needed to explore hidden truths of this one of the oldest tradition of hand block printing.

Tarapur Print: A Craft Jewel of Madhya Pradesh

Background 

Ummedpura-Tarapur twin villages situated on the banks of "Maa" Gambhiri river in Neemuch district of Madhya Pradesh. Twin villages demarcated by a bridge made on the river were famous for its 400 years or even older than this craft of Nandana hand block printing practiced in these two villages only by traditional "Hindu Chippa" community belongs to the Sant Namdev tradition supported by "Muslim Nilger" community famous for indigo dyeing. 

Limited to tribal market, laborious process, limited design and color combination,  and increasing cost of nandana print was the reason behind decrease in demand too. It was clearly an indication for them to do something new or stop the work. Many families stopped their traditional work of nandana 2 decades ago and started other business. Few families still continued their family tradition with concern for future of their tradition. While they were in dilemma to continue the craft or not few started searching for new markets and possibilities to innovate the existing techniques. In this time less than 10 families were left in this business who were practicing nandana hand block printing and sometimes other techniques of hand block printing.

In this struggle period some 3 decades ago few exporters contacted hand block printer family of Late Shri Purushottamji Jhariya for indigo and different design combination in red and indigo color. Though they were doing it since ages but not commercially marketed well and it is how a new technique of block printing evolved.

In this technique they started concentrating on use of alizarin print (red and black) combining with indigo Indigo dabu work to get a red. black and indigo blue color combination with variety of block designs. 

They started calling this technique as "Alizer-Indigo" technique to differentiate it.

Marketing as Tarapur print

When Pushyamitra co-founder of EcoFab started working with the family of Late Shri Purushottamji Jhariya in Tarapur some 3 years ago while doing his thesis started documenting the various techniques practiced by the 2 families left in this place comes to know about 4 techniques practiced by them were:

1. Alizarin print (Red & black) 

2. Dabu print (Resist techniques and mainly dyed with indigo)

3. Alizer Indigo print (Combination of Alizarin red and black & Dabu indigo)

4. Nandana print (Traditional signature craft of hand block printing)

Tarapur as a craft village and home to a varieties of craft of hand block printing was facing an identity crisis. Bagh and Bagru villages were already famous for its unique alizarin hand block printing depicting their geographical identity. Then it was decided by Pushyamitra with Jhariya borthers (Pawan Jhariya & Banwari Jhariya) to market this unique combination of alizarin print and dabu print as "Tarapur Print" in the market.

It is how name of Tarapur print came into existence. Today Tarapur print evolved as an important hand block printing technique and quite famous among craft lovers.

Process

Process of Tarapur print is time consuming and laborious too as it is a combination of two different hand block printing known as Alizarin printing and Dabu printing. 

Fabric is first treated with a solution of soda ash, castor oil and sea salt now a days a ready combination known as TRO (turkey red oil) is available in the market is used. After this pre washing treatment fabric is dyed with harda (myrabalan) solution then it is ready for printing with alum mordant and paste made of iron rust and jaggery solution mixed with tamarind seed powder.

After printing it is kept for 2-3 days then washed in flowing river or in tank then it is dyed with alizarin using bhatti (boiling) process. After bhatti process fabric again printed with resist paste made from clay, gum and lime to hide red portion and where we need white design in base now fabric is dyed with indigo an kept for a day. After washing and post mordant fabric is ready to market.

Tribal Tale - Jawariya Lugda A Kind of Tribal Saree

About Jawariya Lugda

Jawariya means jowar ka dana (Sorghum or cereal grass) is a very old and traditional design used in hand block printing inspired from the nature. Once it was a trademark design of tribal people of Jhabua, Bagh, Neemuch, Ratlam and neaby places in Madhya Pradesh. In tribal Jawariya lugda (used as a Saree) is considered necessary during marriage.

Without Jawariya lugda a kind of tribal saree no marriage ceremony considered completed among tribal even today. A thick cotton fabric like poplin cotton of 58 inches width and 2.6 meter in length is used by tribal bride as a short saree. Fabric is hand block printed with alum using "Jawariya" design then dyed with alizarin to get complete red color and then dyed with  loose pink color. 

Traditional Red Jawariya Lugda

This Jawariya lugda is used by tribal bride as a Saree which is a must during marriage ceremony by wrapping it around the body. 

For urban people it is like a thick cotton material to make a kurta. EcoFab has done some changes in the color combination in this traditional "Jawariya" to make it a wearable art. A combination of red with iron black (Black color made from iron rust and jaggery powder), complete black combination.

Hand Block Printing Centers 

Traditionally "Jawariya" design was used by craftsman of various hand block printing centers in India including Madhya Pradesh and Rajasthan.  In Madhya Pradesh it was printed in Bagh village and Tarapur village to fulfill the demand of tribal but today this design is equally liked and appreciated by urban customers. This design and tradition of printing lugda is continued by Jhariya family from Tarapur village in Madhya Pradesh.

Madder roots: A source of natural herbal dye

Madder roots: Introduction & history

Madder or Manjishta (मंजिष्ठ) in Hindi is one of the oldest known sources of natural red color in dyeing fabrics worldwide. Roots of madder is used as a rich source of red dye since ages. It is found that even 3000 years B.C. in Mohen-Jo-Daro civilization it was used for dyeing clothes. There are two different species of madder found in the nature, rubia tinctoria and rubia cordifolia. Rubia cordifolia is better known as Indian madder or common madder and rubia tinctoria is known as dyer's madder. Both the varieties are rich sources of purpurin and alizarin which gives shades of pink, red and orange with different mordants.

Madder Plant (Source: http://www.planetayurveda.com)

Either madder roots or its powder is boiled in water to extract the dye stuff and then fabric dyed with it. Madder is one of the most useful natural dye used worldwide as source for variants of red. It is very fast dye if mordant is used properly.

In past in India madder roots and al roots (morinda tinctoria) were used as a source of red dye in hand block printing industry. In traditional hand block printing madder was used as a source of natural alizarin to get red dye color where alum is printed but today it is replaced by synthetic alizarin.

Herbal importance 

Madder is not just a source of dye but used as a main element in Ayurveda. A tonic called "Mahamanjishthadi Kada"  is named after its use in preparing it by mixing other herbs in certain proportion. This tonic is very useful and recommended by physicians for blood purification. It is having skin healing property too. People who are suffering from skin irritation or any other skin related problem madder dyed fabrics may work as a healer for them.

Dried Madder Roots 

Madder is very useful natural herbal dye which does not contaminate the water resources and works as a skin healer too. For a healthy skin madder dyed fabrics is a good choice.

Ecofab's work with madder

Ecofab has started working with madder roots since its inception to over dye traditional hand block print fabrics and sarees with it to get hues of pink and red. While working with craftsman came to know that today they are using synthetic alizarin in place of natural source of alizarin to get red color in place of alum print. 

Madder roots powder

Ecofab started experimentation with madder to dye traditional hand block print fabrics with it but didn't got success initially. Result got as faded red color or no color while dyeing with madder roots. Ecofab continued experimentation and finally got the formula to get shades of red dye, orange and turkey red in place of alum printing in hand block printing. Ecofab created a madder formula to extract red color from madder. It gave a new dimension to Ecofab's work with traditional hand block print to regain its roots. Now valuable natural red dye is rejuvenated. 

Few of the finished products dyed with madder formula below:
