CALCIMINING AND PAINTING.
Calcimining. In calcimining, a great deal de pends on the condition of the walls. If they are smoked, they should be thoroughly washed. If they are spongy, or very dry, and soak up too freely, they should be coated, with a size made of glue and common soft soap. Take gilders' whiting or Paris white, or about equal parts of each, and soak it in water; put in a trifle of ul tramarine blue to give it a blue tint. Dissolve good white glue in water in the proportion of one-fourth pound of glue to a common pail of cal cimine. Mix the whiting and glue together and thin with cold water to about the consistency of paste. Strain the mixture through a sieve; lay it on the wall crosswise, viz: making the strokes with your brush to cross each other.
Oil for oiling floors. Mix four quarts raw lin seed oil, two quarts spirits turpentine, one pint best coach japan.
To preserve paint brushes, when not in use. Cleanse them thoroughly after using and suspend them in water. Varnish brushes should always be kept in raw linseed oil when not in use.
Painting inside walls. First coat. The paint should be mixed quite thin with linseed oil.
Second coat. A trifle thicker, with three parts oil and one part turpentine. Third coat. Thin glue size, made of about three ounces of good glue in one gallon of water. Fourth coat. Paint thinned with equal parts oil and turpentine. Fifth coat. Paint thinned with clear turpentine.
Fireproof paint for woodwork. Owing to the fact that waterglass is gradually dissolved out of the wood, while chloride of zinc is volatile at the temperature where wood ignites, the author, F. Sieburger. proposes the following: Two coats of a hot saturated solution of three parts alum and one part ferrous sulphate are first applied and allowed to dry. A third coat is a dilute solution of ferrous sulphate, into which white potter's clay is stirred until it has the consistency of good water colors. Another method is to ap ply hot glue water as long as it is absorbed into the pores of the wood. A: thick coat of boiled glue is then applied, and, while fresh, is dusted over with a powder composed of One part sul phur, one part ochre of clap, and six parts fer rous sulphate.
