Did India invent the mordant-dyed, colour-fast printed cottons that Europe later copied?
India first (well documented)Technology & engineering
Indian claim
Indian dyers developed mordant dyeing (using alum and iron salts to fix madder reds and blacks) and resist dyeing with indigo, producing bright, washable printed and painted cottons — chintz (from Hindi 'chheent') and calico (from Calicut).
Evidence for the Indian claim
- Indian block-printed, mordant- and resist-dyed cottons from Gujarat were found at Fustat (Old Cairo) and dated to the 13th–14th centuries and earlier.
- European companies imported Indian chintz on such a scale that France and Britain banned or restricted it (e.g. Britain's Calico Acts of 1700 and 1721) before learning the methods.
Commonly credited to
European textile printers in Britain, France and the Netherlands made printed cottons in the 17th–18th centuries, and mordants were known elsewhere (e.g. Egypt) in antiquity.
Evidence for the other claim
- Mordant dyeing of wool and linen was practised in ancient Egypt and the Mediterranean.
What historians and scientists say
India mastered and led the world in colour-fast dyed and printed cotton for centuries; European printers learned the techniques from Indian cloth in the 17th and 18th centuries.
