- PAINTS AND COLORS -
Every green color, simple or compound, when mixed up with a white ground, becomes soft, and gives a sea-green of greater or less strength, and more or less delicate, in the ratio of the respective quantities of the principal colors. Thus, green oxides of copper, such as chrome green, verdigris, dry crystallized acetate of copper, green composed with blue verditer, and the Dutch pink of Troyes, or any other yellow, will form, with a base of a white color, a seagreen, the intensity of which may be easily changed or modified. The white ground for painting in distemper is generally composed of Bougival white (white marl), or white of Troyes (chalk), or Spanish white (pure clay); but for varnish or oil painting, it is sought for in a metallic oxide. In this case, ceruse or pure white oxide of lead is employed.
• To make Sea-Green for Distemper.
Grind separately with water, mountain-green and ceruse; and mix up with parchment size and water, adding ceruse in sufficient quantity to produce the degree of intensity required in the color. Watin recommends the use of Dutch pink of Troyes and white oxide of lead, in proportions pointed out by experience; because the color thence resulting is more durable.
In the case of a triple composition, begin to make the green by mixing Dutch pink with blue verditer, and then lower the color to sea-green, by the addition of ceruse ground with water.
• To make Sea-Green for Varnish and Oils
Varnish requires that this color should possess more body than it has in distemper, and this it acquires from the oil which is mixed with it. This addition gives it even more splendor. Besides, a green of a metallic nature is substituted for the green of the Dutch pink, which is of a vegetable nature.
A certain quantity of verdigris, pounded and sifted through a silk sieve, is ground separately with nut-oil, half drying and half fat; and if the color is intended for metallic surfaces, it must be diluted with camphorated mastic, or gallipot varnish.
On the other hand, the ceruse is ground with essence, or with oils to which 1/2 of essence has been added, and the two colors are mixed in proportions relative to the degree of intensity intended to be given to the mixture. It may readily be conceived that the principal part of this composition consists of ceruse.
If this color be destined for articles of a certain value, crystallized verdigris, dried and pulverized, ought to be substituted for common verdigris, and the painting must be covered with a stratum of the transparent or turpentine copal varnish.
The sea-greens, which admit into their composition metallic coloring parts, are durable and do not change.
The last compositions may be employed for sea-green in oil painting, but it will be proper to brighten the tone a little more than when varnish is used, because this color becomes darker by the addition of yellow, which the oil developes in the course of time.
