Paint boxes should contain only the three primary colors (red, yellow, blue) and black, so the child can learn to mix his own colors.
Labeled boxes for materials should be kept on the play shelves, and scraps of everything usable from the household kept in these.
Dry clay powder is the cheapest form of modeling material; composition clay or plasticine are cleaner.
Plaster of Paris and Portland cement are easy material for children to work with. They should be mixed with lukewarm water until the consistency of thick cream.
Dry colors purchased at the paint shop may be mixed with the dry clay powder, plaster of Paris, or cement, for color effects.
Children who live in the vicinity of a pottery can have their clay pieces fired. Enamel paint or water glass will waterproof clay. Decorations may be made with water colors or shellac varnish mixed with dry colors.
Handwork that is Injurious. The fine muscles of the fingers and eyes are undeveloped in the child under six years, and the nervous system is easily fatigued or overstrained. Handwork that involves use of small objects, as toothpicks, straws, lentils, peas, tiny beads, cambric needles, thread, 1-inch blocks, small papers, is a nervous strain upon the child. Fine lines, dots, holes, the following of a fine line in cutting or coloring, are also injurious to the eyes. Such fine material and work is no longer used in kindergartens that have respect for child hygiene.
