Luminous Colors for Artists' use are prepared by using pure East India poppy oil, in the same quantity, instead of varnish, and taking particular pains to grind the materials as fine as possible.
For Luminous Oil-Color Paints, equal quantities of pure linseed are used in place of the varnish. The linseed oil must be cold-pressed and thickened by heat.
All the above luminous paints can be used in the manufacture of colored papers, etc., if the varnish is altogether omitted, and the dry mixtures are ground to a paste with water.
The luminous paints can also be used as wax colors for painting on glass and similar objects, by adding, instead of the varnish, 10 per cent more of Japanese wax and one-fourth the quantity of the latter of olive oil. The wax colors prepared in this way may also be used for painting upon porcelain, and are then carefully burned without access of air. Paintings of this kind can also be treated with waterglass.
