Burnt Carmine is, according to its name, the carmine of cochineal partially charred till it resembles in colour the purple of gold, for the uses of which in miniature and water-painting it is substituted, and has the same properties except its durability; of which quality, like the carmine it is made from, it is deficient, and therefore in this important respect is an ineligible pigment. A durable colour of this kind may, however, be obtained by burning madder carmine in a cup' over a spirit lamp, or otherwise, stirring it till it becomes of the hue or hues required.
