BLACK PIGMENTS
Ivory Black, Lamp Black, Indian Ink.
Ivory Black is made from ivory and bone charred to blackness.
Lamp Black is a smoke-black, being a finely divided soot formed by the incomplete combustion of hydrocarbons.
Genuine Indian Ink does not come from India, as might be supposed, but from China. There are, however, several other varieties in liquid form. It is generally admitted that carbon-black forms the bulk of all these.
All these black pigments are quite permanent.
