The branch of the art which may be treated as an accomplishment, is the decoration of glass, flower-stands, lamp-shades, and similar articles, with light and elegant designs. Flowers, birds, butterflies, and pleasing landscapes afford an extensive range of subjects, which are suitable to this style of ornamental painting. The glasses may be procured ready ground. The outline may be sketched in with a black lead pencil; the lead can be washed off with a sponge when the colors are dry. The whole of the colors employed must be transparent, and ground in oil; opaque, or body colors, will not answer the purpose.
They may be purchased in small bladders, only requiring to be tempered with fine copal or mastic varnish, and a very little nut oil, to be ready for use. Blue is produced by Prussian blue; red, by scarlet or crimson lake; yellow, by yellow lake or gamboge; green, by verdigris, or mineral green, or a mixture of Prussian blue and gamboge; purple, by a mixture of lake and Prussian blue; reddish brown, by burnt sienna; and all the other tints may be obtained by combinations; for white, or such parts as are required to be transparent, without color, the varnish only should be employed. A very chaste and pleasing effect may be produced by painting the whole design in varnish, without color.
It is an advantage to this style of painting that but few colors are required; as from the nature of the subjects, and their purpose as ornaments, brilliancy is more desirable than a nice gradation of tints. The work must, of course, be carefully dried, but may afterwards be cleaned with a sponge and cold water.
25.—PAINTING ON VELVET.
Painting on velvet as well as on glass is an old art revived. No art that is really beautiful in itself will pass away entirely. As these paintings are very pleasing to the eye, and easy of execution, it is well to know how to paint them. The following directions are taken from a reliable English work.
The colors for this style of painting are sold at the drawing material warehouses in a liquid state, and prepared for use. In addition to these, a brilliant rose-color is obtained from the pink saucers, by dropping a little weak gum water upon the color, and rubbing it with a brush. A deep yellow may also be produced by pouring a few drops of boiling water upon a small quantity of hay saffron.
It is necessary to mix gum water with all the colors made, to prevent their spreading into each other; gum dragon is the best for this purpose. The brushes used are called scrubs; they consist of a small stick, with a camel’s-hair brush cut off quite short at one end, and at the other, a brush of bristles of a much harder description. A small box of black lead is necessary, and a piece of list rolled tightly round, to the diameter of about two inches, to be used as a sort of brush with the black lead, for making outlines in the manner we shall presently direct. A piece of linen rag, to wipe the brushes on, should also be provided.
The most brilliant flowers, fruits, shells, birds, &c., are well adapted to this style of painting. The outline of the subject may be sketched in pencil on the velvet, which is of such a very delicate nature, that the greatest nicety is necessary to keep it in a state of neatness. Care should also be taken that the sketch is correctly made, as an error cannot be effaced by rubbing out, as on paper. It is a safer method, however, to make the sketch on drawing-paper, and to prick the outline very closely with a fine needle; then, the velvet being previously nailed on a flat piece of wood of a proper size, the pricked pattern may be laid over it, the roll of list dipped into the black lead powder, and rubbed regularly over the pattern from side to side; be careful to touch every part, and on removing the pattern, a perfect outline in black dots will appear on the velvet.
Where a set of articles of the same pattern is undertaken, this is a very good plan, as it insures accuracy, and saves the trouble of making separate sketches.
Even those who have no knowledge of drawing on paper, may produce a design on velvet with ease and correctness, by tracing off against a window, or by means of tracing paper, any drawing or print which they wish to copy, and pricking the tracing on the velvet in the manner just described. In order to keep the margin of the velvet from being soiled in the progress of painting, a piece of thick paper should be laid over the whole, and an aperture cut in the middle, sufficiently large to expose the part to be worked on. Each brush should be kept for that color alone, to which it has once been appropriated.
