ter, the silk was then
sized and smoothed with a paddle. The use of silken fabric of the finest
weave, prepared with a thick sizing, became general during the Sung
dynasty. Papers were made of vegetable fibres, principally of bamboo.
Being prepared, as was the silk, with a sizing of alum, they became
practically indestructible. Upon these silks and papers the painter
worked with brush and Chinese ink,[1] color being introduced with more
or less freedom or restraint.

The brushes are of different types. Each position of the brush conforms
to a specific quality of the line, either sharp and precise or broad and
quivering, the ink spreading in strong touches or thinning to delicate
shades.

The colors are simple, of mineral or vegetable origin. Chinese painters
have always avoided mixing colors so far as possible. From malachite they
obtained several shades of green, from cinnabar or sulphide of mercury, a
number of reds. They knew also how to combine mercury, sulphur and potash
to produce vermilion. From peroxide of mercury they drew coloring powders
which furnished shades ranging from brick red to orange yellow. During the
T'ang dynasty coral was ground to secure a special red, while white was
extracted from burnt oyster shells. White lead was later substituted for
this lime white. Carmine lake they obtained from madder, yellows from
the sap of the rattan, blues from indigo. To these must be added the
different shades of Chinese ink and lastly, gold in leaf and in powder.

[1] Chinese ink is a very different composition from the ink of
Western countries. It is a solid made of soot obtained by burning
certain plants, which is then combined with glue or oil and moulded
into a cake and dried. Other ingredients may be added to produce sheen
or a dead finish. It improves with age if properly kept. The cake is
moistened and rubbed on a slab, and the ink thus obtained must be used
in a special way and with special care to produce the full
effect.--TRANSLATOR.

The brush-stroke in the painting of the Far East is of supreme importance.
We know that this could not be otherwise if we recall that the characters
in Chinese writing are ideographs, not actually _written_, but rather
_drawn_. The stroke is not a mere formal, lifeless sign. It is an
expression in which is reflected
