404 Paint, Economical. 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.

Paint, To remove old. Wet the place with naphtha, repeating as often as is required, but frequently one application will dissolve the paint. As soon as it is softened, rub the surface clean. Chloroform, mixed with a small quantity of spirit ammonia, has been very successfully employed in removing the stains of dry paint from wood, silk, and other substances.

Paint, To destroy. Mix one part by weight of pearlash with three parts quick-stone lime, by slaking the lime in water and then adding the pearlash, making the mixture about the consistency of paint. Lay the above over the whole of the work required to be cleaned with an old brush, let it remain fourteen or sixteen hours, when the paint can be easily scraped off.

Paint, To remove. In those cases where it is requisite to remove painting entirely from its ground, it is usual to resort to mechanical scraping, or to the very dangerous operation of setting fire to the painted surface immediately after washing it over with oil of turpentine, called turps, for burning off the paint from the old disfigured work, an operation which may be safely and more easily accomplished by laying on a thick wash or plaster of fresh-slaked
