made and put on exhibition, and orders taken, requiring a deposit on each order. These were then turned in to the shop department and the toys made on the productive plan.

The boys in the shop would receive school checks, Fig. 7, for the total number of points that they earned for the semester. These checks could then be used by them towards the purchasing of any of the toys that were put on sale; a certain number of points required for the purchase of different toys.

This plan was made possible by adding on to the number of orders received an additional number equal to the number of boys in the shop. For example, twenty-four orders for toy milk wagons were received by a class of twenty-four boys. Then instead of making twenty-four toy milk wagons we doubled the number and made forty-eight of them. The price that was figured on for the twenty-four orders would more than cover the cost of material for the other twenty-four articles that the boys would be able to buy with their earned checks.


CHAPTER II

Coloring Toys

10. Sanitation Emphasized.—All application of color to toys should carry with it a realization that toys are meant primarily for children and that all paints should therefore be free from poisonous compounds.

All paints used should be of good quality so that it will not come off easily to discolor the hands or tongues of children who cannot resist the temptation of sticking everything possible into their mouths.

11. Preparation of Surfaces.—Wooden toys may be finished quite bright and in various colors.

Before applying the color it is absolutely necessary that every part of the toy has been thoroly sanded. Where sanding is done by machine, care should be taken not to sand the wood too much. Many difficulties may arise from too much as well as from too little sanding. In hand sanding, the use of a block 2½" × 3½", to which is glued a piece of cork, is recommended.

12. Application of Water Colors.—Toys may be colored by the use of different materials and by various methods. Kalsomine colors, opaque water colors, variously known as show card colors, liquid tempera, and letterine,—all come under the heading of water colors. All but the kalsomine may be obtained in small jars and ready for use. Kalsomine colors come in powder form in various colors and may easily be prepared by mixing with water and a little glue to bind the parts together. They are much cheaper than the ordinary forms of transparent and opaque water colors. They may be applied with the ordinary water color brushes.

After a coat of water color has been applied to the toy, it may be necessary to remove the rough parts with very fine sand paper. Care should be taken not to "cut thru" when sanding.

To preserve and protect the water color on the toy a coat of white shellac may be applied. If a more durable finish is desired a coat of good clear varnish over the shellac will serve the purpose.

13. Analine Water Stains.—For general finishing of toys analine water stains will produce excellent results. They are known for their ability to penetrate the wood deeply and the ease with which any shade can be produced. Water stain raises the grain of the wood more than any other. This makes it necessary to sandpaper down the raised grain until smooth and then proceed with the shellacking and varnishing until the desired results are obtained.

In preparing analine water stains, only analines that are soluble in water are used. Place an ounce of the analine to a quart of hot or boiling water, pouring the water over the dye-stuff and stirring meanwhile with a wooden paddle or stick. Soft water is the best. In about an hour the dye may be filtered thru a piece of fine woven cloth. As metal is apt to discolor the dye, it is better to use a glass container. If the prepared solution is too strong it may be diluted in more water. Use hot water for diluting the stain.

The work with water stain must be done quickly in order to obtain a uniform coloring on the surface. Water stains are used a great deal where the dipping process is employed in the finishing of toys. A hot dipping stain is preferable to a cold dipping stain, first, because it penetrates more readily and second, because it dries quicker.

14. Formulas for Analine Water Stains.—(Stock Solutions).

Red: Rose benzol five parts, water ten parts.

Rose Red: Dissolve 3 oz. Rose Bengal in 5 pints of water.

Blue: (a) Dissolve 1 oz. of the best indigo carmine in 8 oz. of water. (b) Prussian blue dissolved in water.

Dark Blue: Dissolve 3 oz. Bengal blue in 3½ pints of boiling water, and stir and filter the fluid in ten minutes time.

Green: Mix Prussian blue and raw sienna in such proportions as will give the desired color. Mix in water.

Brown: Dissolve 3 oz. of Bismark brown in ½ gal. of water.

Yellow: Auramine 4 parts, sulphate of soda 10 parts, mixed in water.

Black: Nigrosine black, four ounces, dissolved in one gallon of boiling water.

When wanted for use, these analines may be diluted with water. The rule is, an ounce of analine to the gallon of water to form a working stain. Or to a pint of the stock solution, as it is called, you may add three pints of water.

15. Oil Stains.—It will be found that quicker work can be done with oil stain than with water colors. For that reason, oil stains are also used a great deal as a dipping stain. In preparing oil stains, the best mineral or earth pigments to dissolve with turpentine are Van Dyke brown, chrome green, burnt and raw sienna, and lamp black.

16. Shellacking.—There are two kinds of shellac, orange and white. The white shellac is orange shellac that has been bleached. The purpose of shellac as commonly understood is to give a quick coat over the stain. The thin coat formed serves as a protector for the stain and also as an undercoater for the following coat of varnish. In this way at least one coat of varnish is eliminated and a great deal of time saved because the shellac dries within a few minutes. To thin shellac use denatured alcohol.

On cheaper toys a coat of shellac only may be used as a covering for the color stain. If orange shellac is used it will be found that it effects the color of the stain used. White shellac also produces a slight change in color and for this reason many working with toys will use a good clear varnish instead.

17. Varnishing.—Two or three coats of varnish will produce a very durable finish. The first coat of varnish ought not be quite as heavy as the succeeding coats. If the varnish is of extra heavy body it should be reduced slightly for the first coat. The best varnish reducer is thin varnish. To prepare this reducer, take one part varnish (the same varnish to be reduced), and two parts of turpentine. Shake these together well and let stand twenty-four hours before using. This will reduce the consistency of the varnish without tearing down the body as pure turpentine would. The first coat of varnish should be allowed to dry thoroly before the second coat is applied.

Oil varnishes made from good hard gums, pure linseed oil, and turpentine, are the most valuable. In using turpentine to thin varnish care should be taken that adulterated turpentine is not
