Charles Smith, of Piccadilly, in the County of Middleser, superfine Colour manufacturer; for an Improvement in the Method or Form of making up superfine Oil and Water Colours, for Drawing, Painting, and other Purposes. January 15, 1819.
This invention consists in inclosing various kinds of superfine oil and water colours in wood, or any other material, so as to be thrne a species of coloured pencils, to work by dipping in liquid, and not dry and chalky, like those before known, capable of making perfect transparent or opaque drawings, on paper, or wood, linem, or any other material, by being wetted or moistened with water, oil, varnish, spirit, or any other liquid matter. To make them, take wood, or other grooves, similar to those used for black-lead pencils, and inclose in them all kinds of the best superfine water or oil colours, and fasten or glue them up, of whatsoever material they may be made, and round and finish them, so as to appear like a regular coloured drawing-pencil, fit for the purpose of drawing or painting, on any material, with colours, and japan, or colour, each pencil outside of the same teint it contains within.
