118. Lime for Cottage Walls, &c.—Take a stone or two of unslaked white lime, and dissolve it in a pail of cold water. This, of course, is whitewash. The more lime used, the thicker it will be; but the consistence of cream is generally advisable. In another vessel dissolve some green vitriol in hot water. Add it, when dissolved, to the whitewash, and a buff is produced. The more vitriol used, the darker it will be. Stir it well up, and use it in the same way as whitewash, having first carefully got off all the old dirt from the walls. Two or three coats are usually given. For a border at top and base, use more vitriol, to make it darker than the walls. If you have stencil-plates, you can use it with them. This is cheap, does not rub off like ochre, and is pure and wholesome, besides being disinfecting.
119. A White for Inside Painting, which dries in about four hours, and leaves no smell.—Take one gallon of spirits of turpentine, and two pounds of frankincense; let them simmer over a clear fire till dissolved, then strain and bottle it. Add one quart of this mixture to a gallon of bleached linseed oil, shake them well together, and bottle them likewise. Grind any quantity of white-lead very fine with spirits of turpentine, then add a sufficient quantity of the last mixture to it, till you find it fit for laying on. If it grows thick in working, it must be thinned with spirit of turpentine; it gives a flat, or dead white.
120. A Green Paint for Garden Stands, Trellisses, &c.—Take mineral green, and white lead ground in turpentine; mix up the quantity you wish with a small quantity of turpentine-varnish; this serves for the first coat; for the second, put as much varnish in your mixture as will produce a good gloss; if you desire a brighter green, add a small quantity of Prussian blue, which will much improve the beauty of the color.
121. Cheap and beautiful Green.—The cost of this paint is less than one-fourth of oil color, and the beauty far superior. Take four pounds of Roman vitriol, and pour on it a tea-kettleful of boiling water; when dissolved, add two pounds of pearl-ash, and stir the mixture well with a stick until the effervescence cease; then add a quarter of a pound of pulverized arsenic, and stir the whole together. Lay it on with a paint brush, and if the wall has not been painted before, at least two, or even three coats, will be requisite. If a pea-green is required, put in less, and if an apple-green, more, of the yellow arsenic.
122. To Destroy the Smell of Fresh Paint.—Mix chloride of lime with water, with which damp some hay, and strew it upon the floor.
