Lacquer For Polished Brass

The first requisite is to see that the article of polished brass to be lacquered is sufficiently heated to retain the lacquer. This may be done by keeping the surface at a heat above 212 degrees. The lacquer should not be too thick, and may be thinned down with 95 per cent. alcohol, until it appears through the bottle, as a semi-transparent or amber liquid. A few-trials with this lacquer and heat applications after lacquering will give success.

Lacquer For Steel

A lacquer for steel may be made of 10 parts of clear mastic, 5 of camphor. 15 of sandarac, and 5 of elemi gums dissolved in pure alcohol, filtered, and applied cold. This varnish is transparent.

Lacquer For Tin

For a good and cheap lacquer for tinplate: Color lac-varnish with tumeric to impart the color of brass to it, and with annatto to give it the color of copper. Tinplate dipped into molten brass will be coated with it. A deep gold-colored lacquer is made by mixing seed-lac, 3 oz.; tumeric, 1 oz.; dragon's blood, 1/4 oz.; alcohol, 1 pint. Digest for a week, frequently shaking, decant and filter.

Lacquer - Gold

To a pint of strong alcohol, add as much gamboge as will give it a bright yellow color, then add 2 ounces seed-lac in fine powder, and set it in a warm place until dissolved.

Lacquer - Gold - For Metal Goods

A gold lacquer, remarkable both for hardness and for brilliancy of color, is made as follows: A clear solution of shellac is prepared with picric and half per cent. of crystallized boric acid, each separately dissolved in alcohol.

Lacquer - Imitation Japanese

To make a good imitation of Japanese lacquer, take oil of turpentine, 90 parts, and oil of lavender, 120 parts, and after freeing it from water which may be present by adding a small quantity of calcined calcium chloride, and then carefully pouring off the oil, combine it in a bottle with 2 parts of camphor and 30 parts of copal. Place the bottle for twenty-four hours in hot ashes, shaking it occasionally, and finally filter the contents through a cloth. The filtrate is again allowed to stand for twenty-four hours, when the clear, supernatant fluid is poured off from the sediment.

Lead Chloride

Lead chloride is obtained in adding a soluble chloride to a solution of lead salt.

Lead Sulphate

Lead sulphate is a precipitation made by mixing a solution of a lead salt and sulphuric acid.


Lechesne is the name of an alloy consisting of:

900 parts Copper, 100 parts Nickel, 1 3/4 parts Aluminum.

It is also made of:

600 parts Copper, 400 parts Nickel, 1/2 part Aluminum.

Lettering Upon Steel

Steel can be written upon or engraved by first cleaning it with oil, and then spreading a coating of melted beeswax upon it. The writing can be done on the beeswax with any sharp instrument, and the lines and marks thus made should be painted with a fine brush dipped in a liquid made of one ounce of nitric acid and one-sixth of an ounce of muriatic acid. When the written lines are filled with this liquid, it should be allowed to remain five minutes, and then the article should be dipped in water and afterwards cleaned.
