Turmeric






Turmeric is a powder obtained from the ground-up tubers of Curcuma
tinctoria, a plant found in India and other Eastern countries. It
gives a brilliant orange yellow, but has little permanence. It is one
of the substantive colours and does not need any mordant. Cotton has a
strong attraction for it, and is simply dyed by working in a solution
of Turmeric at 60 deg.C. for about 1/2 hour. With silk and wool it
gives a brighter colour if mordanted with alum or tin. Boiling should
be avoided. It is used sometimes for deepening the colour of Fustic
or Weld, but its use is not recommended, as although it gives very
beautiful colours, it is a fugitive dye.
