This beautiful work is very simple ; its characteristic effect being produced by using transparent colors or lakes on glass, and putting tinsel behind. The materials used are oil colors, in tubes, and several sizes of artist’s brushes. These colors are mixed with demar varnish. Any print, or lithograph of flowers, fruits or birds is suitable. Wash your glass with spirits of turpen tine ; when dry, place it over your design, and with a fine brush or steel pen, trace carefully all the outlines and such other lines as will add to the effect.
Any false lines may be removed with turpentine, or, after they are dry, alcohol. For outlining, use lamp-black mixed with demar varnish and thinned with turpentine, till it will flow from a pen. When your outline is dry, place it over white paper, and proceed to color the design with proper colors, mixed very thin with varnish ; shade with extra coats of the same color, giving each one ample time to dry. It will require some practice to mix the colors so as to produce the proper hues.
The only colors really necessary, are scarlet lake, yellow-lake, prussian blue and flake-white. White should seldom be used, and never be mixed with the other colors. The least possible blue added to scarlet will produce crimson ; red and blue make purple ; red and yellow, orange ; blue and yellow, green ; you can vary the proportions so as to produce any color you desire. It only remains after this to cover the rest of the glass with the same black used for outline, only not so thin. If you can procure tinsel of the color of your picture, cut it in the shapes required to fit the design, and fasten it with just enough varnish to hold it in its place. The more crushed and broken it is, the more the picture will sparkle. Out a piece of cloth a trifle larger than the glass, and paste on the edges to hold the tinsel in place, and frame as soon as convenient. Wash your brushes with spirits of turpentine and soap and water.
