2941. Transparent Green Varnish

2941.     Transparent Green Varnish. A beautifully transparent green varnish is made by taking a small quantity of "Chinese blue," with about twice the amount of finely powdered chromate of potash, and stirring these in copal varnish thinned with turpentine. A thorough grinding of this mixture must bo made for the purpose of intimately incorporating the ingredients, as otherwise it will not bo transparent. A preponderance of chromate of potash gives a yellowish shade to the green, and a deficiency increases the amount of blue. This varnish, thus colored, produces a very striking effect in japanned goods, paper-hangings, etc., and can be made very cheaply.

2942. Aniline Transparent Varnishes

2942.      Aniline Transparent Varnishes. The aniline colors are particularly well adapted for the manufacture of transparent lacs, which possess great intensity even in very thin films, and are hence very suitable for coloring glass or mica. Tho process recommended by F. Springmuhl is to pre pare separately an alcoholic solution of bleached: shellac or sandarach, and a concentrated alcoholic solutiou of the coloring matter, which last is added to the lac before using it; the glass or mica to be coated being slight ly warmed. Colored films of great beauty may also be obtained, according to Springmuhl, from colored solutions of gun cotton in other, the coloring matter being here dissolved in alcohol and ether. The collodion film has its elasticity greatly increased by the addition of some turpentine oil; and when applied cold, can bo removed entire. The colored films may now bo cut into any pattern, and again attached to transparent objects.
