History and Technique The manufacturing of sophisticated textiles in India is as ancient as its civilization. The discovery of dyed cotton fabric dates back to the Indus Valley civilization. The art of dying with the use of mordants was well known to Indian dyers some 5,000 years ago. This form of dying which reveals a mastery in the chemistry of dying was responsible for making India famous all over the world for its dyed and printed fabrics.
Animal fibres such as silk and wool accept most natural dyes with comparative ease, unlike cotton, which inherently rejects a permanent bonding. For cotton, an intermediary agent or catalyst called a mordant must be used. Different mordants unite with certain natural dyes to cause them to be bound to the cotton fibre. The mordant, a metallic oxide, combines with the dye to create an insoluble substance that coats the fibre. Different mordants can yield different yet predictable colours in the same dye bath. Varying concentrations of the mordants can affect colour density. The manipulation of the kinds of mordants, their purity, and their density, is one of the secrets of the dyers art.
The fabric is laid on a low bench on a pad formed of several layers of heavy cloth. The printer squats in front of this with the dye in a pan or earthen vessel at his side. The vessel contains a frame that is covered with layers of cloth or blanket, forming a pad that becomes saturated with colour and on which the blocks are pressed before stamping.
