Colours are prepared for wax-painting by grinding them with a gluten. They are the same in substance as those mixed with oil for oil-painting. The gluten is made as follows:—
| Resin | 1 |
| White wax | 4 |
| Essence of spikenard | 16 |
A harder gluten can be made by substituting copal for the gum-animé.
There is a vast field for profitable labour in the cleaning and restoration of old pictures, as well as of antiques of all kinds, and thousands of young or even elder artists, whose life is a painful struggle towards becoming known, would do well to endeavour to raise the art of restoration to its proper place, instead of being ashamed to descend to it.
The restorer should make a point of studying varnishes, oils, and colours, with great care. Let him read what cyclopædia articles and books he can find on these subjects, and make all practical inquiries from manufacturers and dealers. He should, if he intends to seriously practise the art, study chemistry. I can imagine no better restorer than a skilful analyst. There is a great deal yet to be learned regarding colours, and most of it will come by the way of chemistry. A great deal is, however, actually being revived or arriving as new from training “the popular eye” to hitherto unaccustomed shades, tints, and tones. During the Middle Ages, when culture was exhausted in art and decoration, there was a marvellous development in this respect, even in most delicate details, though much of it now seems so “loud” or excessive to us. We have of late years learned a great deal from China and Japan as regards subdued colours. It may be that as in Oriental music even the tenth part of a note becomes as distinct to the practised ear as a natural one, so these blendings and subdivisions of hues may be as perceptible to people as the normal colours. All of this should be carefully studied by the restorer as well as the painter.
The restoration of a fine work of art which has become utterly dim, wrinkled with a thousand lines, and, it may be, utterly ugly to beauty and freshness, is so much like a resurrection or transfiguration to new life, youth, and beauty, that poets have not failed to use it as a simile for all that is expressive of renaissance. Thus Dean Hole, in his Memoirs, remarks that, “as when some beautiful picture which has been concealed and forgotten, removed in time of battle lest it should be destroyed by the enemy, is found after many years, and is carefully cleaned and skilfully restored, and the eye is delighted with the successive development of colour and of form, and the life-like countenance, the historical scene, the sunny landscape, or the moonlit sea come out once more upon the canvas; so in that great revival of religion which began in England more than half a century ago the glorious truths of the Gospel were restored.” Regarded in itself, the art of restoring beauty is both beautiful and noble, and deserves to be regarded as such.
GENERAL RECIPES
Recipe.—The word. A formula or prescription is a recipe, derived from the Latin word recipe, meaning take. An acknowledgment of money paid is a receipt, from receptus, or received. A description of the materials to be used in making a pie is not a receipt, but a recipe.—Familiar Errors.
To clean Woollen Cloth.—Rub it with sal-ammoniac and water till clean, then wash with pure water. This liquid is very useful, when any article of clothing has been stained by vinegar, wine, or lemon, to restore the original colour.
An old-fashioned but excellent method of cleaning greased silk ribbons or cloth is as follows:—Lay the ribbon on a wad or flat surface of cotton wadding, strew on this dried clay, or calcined magnesia, or whiting, and over this another layer of wadding. Pass over it a flat-iron not too warm. The oil or grease will be absorbed into the cotton. Repeat this till the cure is effected. If any spots still remain, paint them with yolk of egg, dry the stuff in a draught of air, and when quite hardened remove the yoke and wash with water.
