wrinkles and spots of water,) press it well on until every part is
stuck fast, then carefully rub the paper all away to a mere film; give the glass then, over this film, another coat of demar varnish, which will make the film transparent; let it dry; then place the glass, with the varnished side towards you, between you and the light, and you will see the outlines of the picture quite distinctly; you may then paint on the back with tube paints, mixed with a little demar varnish to assist in drying, to suit your taste. For instance, if the picture is that of a lady, you may paint the dress red, the shawl or cape, as it may be, blue, the face flesh colour, (which colour may be made by mixing a little red with white,) the bonnet scarlet, the shoes black; if trees, have them green, &c. All you want for this painting you may also buy at the druggist's. This painting is very simple and elegant, it is commonly taught at a cost of $3. Try it, you cannot fail. 3. TRANSFER VARNISH Take of Canada balsam 3 drachms; gum sandric 3 drachms; spirits of wine 1/2 pint. Dissolve the balsam and gum in the spirits of wine and it is ready for use. 4. WHITE SPIRIT VARNISH--THE VERY BEST. Take of gum sandrack 4 ounces; mastic 1 ounce; Elmi rosin 1/2 ounce; Venice turpentine 1 ounce; alcohol 15 ounces. Digest in a bottle, frequently shaking, till the gums are dissolved, and it is ready for use. |
