Madder and Aniline Black.

Second Style.—Garancin Colours.

As a general rule the effedls produced with crude madder can also beobtained by the use of garancin (see p. 257). The shades, both dyed andprinted, with this preparation are fully equal to madder-colours—properly so-called—in brilliance, but fall short of them in permanence and in power ofresisting the adlion of soap, light, air, &-c. They are, nevertheless, commonlyclassed amongst “ fast colours,” and are far more permanent than the shadesobtained with the woods. The best qualities of garancin yield colours whichwill stand soaping to some extent, and which have this advantage overmadder, that they scarcely stain the white unmordanted grounds, and conse-quently the operation of clearing ( avivage) is much less severe.
