The Laque De Garance Which Was Tinged With The Rouge Of Carthamus





and was of course inferior in durability. As, however, liquid ammonia

and alkalis generally dissolve the colours of cochineal, lac, and

safflower, the test is simple. If the liquid remain uncoloured on

adding ammonia to an assumed madder lake, in all probability the pigment

is genuine.



TTITLE ROSE MADDER.



The exquisite flowers of Bartholomew, Miss Mutrie, and others, give

evidence of the beauty, purity, and stability of the reds of madder,

both in water and oil. This variety, less intense than the preceding and

without its carmine hue, is of a rich rose colour--a true rose--tending

neither to crimson, scarlet, nor purple. Marked by a peculiar softness,

and an unusual clearness in its pale washes, rose madder affords the

most perfect carnation tints known. Not liable to change by the action

of light, impure air, or admixture with white lead and other colours, it

resembles all madder lakes in these respects. Like them, too, it is but

a tardy dryer in oil unless thoroughly edulcorated, and does not work in

water with the entire fulness and facility of cochineal pigments. When,

therefore, permanence is of no consideration, the latter may still be

preferred. In those works, however, where the hues and tints of nature

are to be imitated with stability and pure effect, the rose colours of

madder are become indispensable. They have this advantage, moreover,

that they possess the property of ultramarine of improving in hue by

time--their tendency being to their own specific prismatic red colour.

As they are too beautiful and require saddening for the general use of

the painter, the addition of manganese brown, cappagh brown, or burnt

umber, adds to their powers, and improves their drying in oils; for

which last purpose a little japanner's gold size may be likewise

employed.



In the light touches of bright clouds or mountains, where a mixture of

cadmium yellow and Chinese white is used, rose madder is invaluable for

glazing over such touches when dry, should they be required of a warmer

hue. The red portion of sunset skies may be improved by a thin wash of

this pigment, tinged perhaps with the above yellow, or with gamboge.

Most serviceable landscape tints are afforded by admixture of rose

madder with cobalt, Indian red, purple madder, yellow ochre, lamp black,

&c. In painting flesh, the lake cannot be dispensed with.

Was a weaker preparation of the preceding, paler in hue and possessing

less colour. It was formerly employed in miniature painting, but with

the decline of that art became less and less used, until it may now be

said to be obsolete. The name, however, still lives, but is applied to
