Zinc-coating
Copper and brass articles may be permanently coated with a layer of pure zinc by boiling them in a solution of chloride of zinc, with an excess of zinc-turnings present in the solution. Gray-iron castings may be coated or galvanized by first cleaning them by abrasion with sand in a tumbling-barrel, then heating and plunging them separately, while hot, in a liquid composed of hydrochloric acid 10 lbs., and sufficient sheet lead to make a saturated solution. In making this solution, add sulphate of ammonia 1 lb., when the evolution of gas has ceased. If the castings are hot enough after dipping them in this solution they will dry almost instantly, leaving a crystallized surface of zinc. They must now be placed in a bath of melted zinc over which, after skimming, some powdered sal-ammoniac has been thrown to prevent further oxidation. Small articles can be lowered into the bath in a wire basket, lifted out, the superfluous metal shaken off, and then cast into water.

Zirconia Light
an intensely brilliant light differing from the Drummond light mainly in the employment of cones of the oxide of zirconium instead of the less durable cylinders of lime. In 1867 Tessié du Motay introduced this light into Paris, and it was there employed for several years to illuminate squares and public buildings and gardens. The cones were formed of burnt zirconia kneaded into a paste withaqueous boracic acid, and hardened in iron molds at a red heat, and a mixture of oxygen and a highly carburetted gas was burnt to raise the cones to incandescence. The light was also once used as an illuminant in public places of Brussels and Vienna, and in the United States in lighthouses and public works.
