by the use of aniline colors. The resulting compound should be stored in jars. To apply liquefy the mass and dip the cork and portion of the neck of the bottle into the liquid; it sets very quickly.
| II.— | Gelatin | 1 ounce |
|---|---|---|
| Gum arabic | 1 ounce | |
| Boric acid | 20 grains | |
| Starch | 1 ounce | |
| Water | 16 fluidounces |
Mix the gelatin, gum arabic, and boric acid with 14 fluidounces of cold water, stir occasionally until the gum is dissolved, heat the mixture to boiling, remove the scum, and strain. Also mix the starch intimately with the remainder of the water, and stir this mixture into the hot gelatin mixture until a uniform product results. As noted above, the composition may be tinted with any suitable dye. Before using, it must be softened by the application of heat. {127}
| III.— | Shellac | 3 ounces |
|---|---|---|
| Venice turpentine | 1 1/2 ounces | |
| Boric acid | 72 grains | |
| Powdered talcum | 3 ounces | |
| Ether | 6 fluidrams | |
| Alcohol | 12 1/2 fluidounces |
Dissolve the shellac, turpentine, and boric acid in the mixed alcohol and ether, color with a spirit-soluble dye, and add the talcum. During use the mixture must be agitated frequently.
Show Bottles.—
I.—Place in a cylindrical bottle the following liquids in the order named:
First, sulphuric acid, tinted blue with indigo; second, chloroform; third, glycerine, slightly tinted with caramel; fourth, castor oil, colored with alkanet root; fifth, 40-per-cent alcohol, slightly tinted with aniline green; sixth, cod-liver oil, containing 1 per cent of oil of turpentine. The liquids are held in place by force of gravity, and alternate with fluids which are not miscible, so that the strata of layers are clearly defined and do not mingle by diffusion.
| II.— | Chromic acid | 1 drachm |
|---|---|---|
| Commercial “muriatic” acid | 2 ounces | |
| Nitric acid | 2 ounces | |
| Water, enough to make | 3 gallons |
The color is magenta.
The following makes a fine pink for show carboys:
| III.— | Cobalt oxide | 2 parts |
|---|---|---|
| Nitric acid, c. p. | 1 part | |
| Hydrochloric acid | 1 part |
Mix and dissolve, and to the solution add:
| Strongest water of ammonia | 6 parts |
| Sulphuric acid | 1 part |
| Water, distilled, q. s. to make | 400 parts |
This should be left standing in a dark, cool place for at least a month before putting in the window.
IV.—Green.—Copper sulphate, 300 parts, by weight; hydrochloric acid, 450 parts, by weight; distilled water, to 4,500 parts, by weight.
V.—Blue.—Copper sulphate, 480 parts, by weight; sulphuric acid, 60 parts, by weight; distilled water, to 450 parts, by weight.
VI.—Yellowish Brown.—Potassium dichromate, 120 parts, by weight; nitric acid, 150 parts, by weight; distilled water, to 4,500 parts, by weight.
VII.—Yellow.—Potassium dichromate, 30 parts, by weight; sodium bicarbonate, 225 parts, by weight; distilled water, to 4,500 parts, by weight.
VIII.—Red.—Liquid ferric chloride, officinal, 60 parts, by weight; concentrated ammonium-acetate solution, 120 parts, by weight; acetic acid, 30 per cent, 30 parts, by weight; distilled water, to 9,000 parts, by weight.
IX.—Crimson.—Potassium iodide, 7.5 parts, by weight; iodine, 7.5 parts, by weight; hydrochloric acid, 60 parts, by weight; distilled water, to 4,500 parts, by weight.
All the solutions IV to IX should be filtered. If distilled water be used these solutions should keep for five to ten years. In order to prevent them from freezing, either add 10 per cent of alcohol, or reduce the quantity of water by 10 per cent.
A Cheap And Excellent Warming Bottle.
—Mix sodium acetate and sodium hyposulphate in the proportion of 1 part of the former to 9 parts of the latter, and with the mixture fill an earthenware bottle about three-quarters full. Close the vessel well with a cork and place it either in hot water or in the oven, and let remain until the salts within melt. For at least a half day the jug will radiate its heat, and need only be well shaken from time to time to renew its heat-giving energy.
Bottle Deodorizer.
—Powdered black mustard seed is successfully employed. Pour a little of it with some lukewarm water into the receptacle, rinsing it afterwards with water. If necessary, repeat the process.

BRASS
Formulas for the making of Brass will be found under Alloys.
Colors For Polished Brass.
—The brass objects are put into boiling solutions composed of different salts, and the intensity of the shade obtained is dependent upon the duration of the immersion. With a solution composed of
| Sulphate of copper | 120 grains |
| Hydrochlorate of ammonia | 30 grains |
| Water | 1 quart |
greenish shades are obtained. With the following solution all the shades of brown from orange brown to cinnamon are obtained: {128}
| Chlorate of potash | 150 grains |
| Sulphate of copper | 150 grains |
| Water | 1 quart |
The following solution gives the brass first a rosy tint and then colors it violet and blue:
| Sulphate of copper | 435 grains |
| Hyposulphite of soda | 300 grains |
| Cream of tartar | 150 grains |
| Water | 1 pint |
| Upon adding to the last solution | |
| Ammoniacal sulphate of iron | 300 grains |
| Hyposulphite of soda | 300 grains |
there are obtained, according to the duration of the immersion, yellowish, orange, rosy, then bluish shades. Upon polarizing the ebullition the blue tint gives way to yellow, and finally to a pretty gray. Silver, under the same circumstances, becomes very beautifully colored. After a long ebullition in the following solution we obtain a yellow-brown shade, and then a remarkable fire red:
| Chlorate of potash | 75 grains |
| Carbonate of nickel | 30 grains |
| Salt of nickel | 75 grains |
| Water | 16 ounces |
The following solution gives a beautiful, dark-brown color:
| Chlorate of potash | 75 grains |
| Salt of nickel | 150 grains |
| Water | 10 ounces |
The following gives, in the first place, a red, which passes to blue, then to pale lilac, and finally to white:
| Orpiment | 75 grains |
| Crystallized sal sodæ | 150 grains |
| Water | 10 ounces |
The following gives a yellow brown:
| Salt of nickel | 75 grains |
| Sulphate of copper | 75 grains |
| Chlorate of potash | 75 grains |
| Water | 10 ounces |
On mixing the following solutions, sulphur separates and the brass becomes covered with iridescent crystallizations:
