Paints From Aniline.

Scientific American 3, 20.7.1861

A patent has been taken out in England, by T. H. Smith, of Islington, for obtaining paints from analine as follows: - He makes up a paste with alum and starch, mixed with water, and to this he adds liquid aniline used for dyeing, and stirs the whole together, then passes them through a grinding mill. The mass is now allowed to drip so as to remove from it the excess of water, when it forms a pigment capable of being used as a paint or for staining paper.
