For pasting labels on tin, use the following:
(1) Four parts shellac, 2 parts borax, 30 parts water; boil until the shellac is dissolved.
(3) Balsam of fir, 1 part; turpentine. 3 parts; use only for varnished labels.
(4) Butter of antimony is good to prepare the tin for the label.
(5) Venice turpentine added to good starch paste makes an excellent mounting medium.
(6) A paste for pasting paper on tin is composed of the following: Dissolve rye flour in a solution of caustic soda, dilute with water, and in so doing stir all the time. To this paste add Venetian turpentine - a few drops to each half pound of flour.
To make a good stove paste: Dissolve ordinary laundry soap to about the consistency of soft soap and add sufficient plumbago and carbon black to make it just thick enough to pour while hot.
Put enough plumbago into black varnish to thicken it. Thin with benzine or gasolene, and polish before dry.
(2) A good paste polish is made by using 2 pounds plumbago, 5 gills Japan dryer or furniture varnish, 1 gill asphaltum varnish, and thin down for use with gasolene; or, can omit the asphalt and use lampblack, a trial of which will determine the quantity. Mix as you want to use the polish.
(3) For cracks in stoves, finely pulverized iron (procured at a drug store) made into a thick paste with water-glass. The hotter the fire the more the cement melts and combines, and the more completely does the crack become closed.
Pewter Britannia metal is composed of:
1 15-100 parts Lead, 1 6-10 parts Copper, 5 7-100 parts Antimony, 81 2-10 parts Tin, or 1 8-10 parts Lead, 1 8-10 parts Copper, 7 6-10 parts Antimony, 89 3-10 parts Tin, or 1 6-10 parts Bismuth, 3 6-100 parts Zinc, 1 6-10 parts Copper, 6 6-10 parts Antinomy, 83 3-10 parts Tin.
Phosphide of copper is made by heating together a mixture of 2 parts of granulated copper, 1 part of finely pulverized coal, and 4 parts of super-phosphate of lime in a crucible, the temperature being moderate. The melted phosphide of copper containing 14 per cent. of phosphorus will separate on the bottom of the crucible. Another method is to prepare phosphide of copper by the addition of phosphorus, by a copper sulphide solution, and boiling same, and sulphur to be added as the sulphide is precipitated. The precipitation is carefully dried, melted and cast into ingots. These ingots, when in perfect condition, are very black.
To prepare phosphide of tin, place a bar of zinc in an aqueous solution of chloride of tin. The sponge-like tin particles, that are separated, are poured when moist into a crucible, upon whose bottom sticks of phosphorus have been placed. The tin is then pressed tightly into the crucible and submitted to moderate warmth. This heating is to continue until the flames of burning phosphorus die out. After the operation is clone there is found on the bottom of the crucible a coarse, crystalline mass, of a white color, consisting of a pure phosphide of tin.
