Paint For Iron

The following are anticorrosive paints for iron: Take 10 per cent, of burnt magnesia, or even baryta or strontia, and mix it cold with ordinary linseed oil paint, and then enough mineral oil to envelope the alkaline earth, the free acid of the paint will be neutral ized, while the iron will be protected by the permanent alkaline action of the paint. Iron to be buried in deep earth may be painted with a mixture of 100 parts of resin, 25 parts of gutta percha, and 50 parts of paraffin, to which 20 parts of magnesia and some mineral oil have been added.

Anti-Corrosive Paint

Take equal parts by weight of whiting and white lead, and half the quantity of fine sand, gravel, or road-dust, and a sufficient quantity of coloring matter. This mixture is made in water, and can be used as a distemper-color, but it is more durable to dry it in cakes or powder after mixing, and then use it as an oil-paint by grinding it again in linseed oil. The proportion of oil recommended for this purpose is 12 parts by weight of linseed oil, 1 boiled linseed oil, and 3 sulphate of lime, well mixed. One gallon of this prepared oil is used to 7 pounds of the powder.

Economical Paint

Skim milk 2 parts, fresh slaked lime 8 ounces, linseed oil 6 ounces, white Burgundy pitch 2 ounces, Spanish white 3 pounds. The lime to be slaked in water exposed to the air, mixed in one-fourth of the milk. The oil in which the pitch is previously dissolved to be added a little at a time, then the rest of the milk, and afterwards the Spanish white. This quantity is sufficient for twenty-seven square yards, two coats.

Paint For Wire-Work

Boil good linseed oil with as much litharge as will make it of the consistency to be laid on with the brush, add lamp black at the rate of 1 part to every 10 by weight of the litharge, boil three hours over a gentle fire. The first coat should be thinner than the following ones.

Metallic Paint

Break common resin into dust or small pieces, and dissolve in benzine or turpentine until the solution acquires the consistency of syrup or molasses, or, equal parts of each of the above hydrocarbons, and any other hydrocarbon that will dry and combine with drying oils, can be used instead of turpentine or benzine. When the solution is complete, it is gradually added to oxide of zinc, which has previously been made into a paste with boiled linseed oil, until the whole mixture acquires the consistency of a paint suitable for use. A white paint of a durable and glossy character is thus produced. Other pigments, such as sulphate of barytes, oxide of iron, Brunswick green, or red lead, can be added to make any desired color of paint. One great advantage of its use is its effectual resistance to heat and moisture. It never blisters or cracks even under the hottest sun or in the most inclement weather.
