carbon ink


carbon ink
(India ink)
   One of the oldest forms of writing ink; commonly referred to as India ink even though the ink was first used in China. In its simplest form carbon ink consists of amorphous carbon shaped into a solid cake with glue. It is converted into a liquid for writing by grinding the cake and suspending the particles in a water–glue medium. Occasionally, a pigmented dye is added to improve the color.
