Natural Indigo - In Cake Form
Indigo was traditionally traded and exported in cake form. These cakes are made as part of the extraction process from indigo plants (indigofera tinctoria) grown in south India. For dyeing the cakes will need to be ground into a powder.
Natural indigo powder is an extract prepared from Indigofera tinctoria which is cultivated for this purpose. Indigo is the legendary source of colourfast blues and its ability to produce a wide range of shades has made it the most successful dye plant ever known. Indigo grows all over the world but flourishes best in hot, sunny, humid areas. Indigo can give clear blues that range from the tint of a pale sky to a deep navy that is almost black. Our indigo comes from a farm in south India and is very strong (approx 50% indigotin). It reduces beautifully in an indigo vat. See Maiwa's Indigo Data Sheet for complete instructions.
