mandarining (uncountable)

1. (historical or archaic) The use of a nitric acid solution to give an orange colour to textiles, such as silk or wool.
   • 1852-1866, Charles Tomlinson, Cyclopaedia of Useful Arts and Manufactures

     By this method, which is called mandarining, an orange colour is given to silk and wool, not from the solution of a colouring matter, but by producing a certain change in the fibre by the action of dilute nitric acid.
