Wax-resist dyeing technique is called Batik. It is originated from Java island, Indonesia. But it is very ancient process. It already existed in Egypt in 4th century BC. It was used to wrap mummies. The technique was also practised in Asia also. The flow of this process set the path from China to Indonesia and then India. In this process, the selection of the cloth for the batik print is very much important to make the fabric well featured. The natural materials like silk and cotton are used for the batik print. Because these fabrics have the capacity to absorb the wax applied in the batik process. The thread count also holds the higher priority for the application of this process unless the fabric will be starched. 
Most commonly, paraffin wax and beewax are used in the batik process. Though there are lots of other wax elements. Perfect temperature, accurate chemical solution of beewax and paraffin wax, sklilled use of resin, dye bath etc are used in the batik technique. Proper care is also taken in each and every step.  

Tussar or Tusar: 
The Sanskrit name of tussar is Kosa. It is famous for its natural gold colors. We get this fabric from a yellowish-brown moth. The scientific name is Antheraea paphia. The silk often is referred as Wild Silk.  India is the main producer of this silk. Mainly, Jharkhand shows the maximum production. India is the second largest procucer of tussar silk. The Tribal women weave this kind of silk from cocoons. Tussar holds varities of textures and colours. 

With the help of the scientific process, these two types of fabric are combined to make Gachi Batik. I purchased this saree from online, Soham Boutique Kolkata. I was attracted by its color. It is unique because of its color combination between coffee color and multi color. Design pattern differs from other batik design. I draped it in a house party.
