added to this also, to make it adhere firmly, especially in an exposed
situation.
Of black pigments.—With respect to a black colour, that made
of burnt oak wood (the bark having been previously taken off) well
ground, is excellent if used while the stucco is wet, that it may hold
firmly, for the Tierra Negra when mixed with the white of the lime
is very grey, but the latter is better than the former for finishing the
dark parts.
Of white pigments.—We have now to speak of the white pig-
ment which is used in fresco painting. This is made of the same
lime as the stucco, but without sand, for which purpose the whitest
quick lime in lumps is chosen; this is slaked in ajar, (which in Cas-
tile is called baho), pouring water on it from time to time, until it
has lost all its causticity, stirring it well until it is thoroughly soaked
and covered with soft water. And this must be managed in the same
way as the stucco, taking off the pellicle on the surface every day,
and this being done, soft water should again be poured over the lime
in great abundance, and it should be again well beaten up, and so
on every day for four months, if possible ; and as the length of time
occupied in preparing this pigment is a great inconvenience, it will
be proper for those who are accustomed to this kind of work, or even
those who are not, to make it in large quantities; and after it has
been well purified, it may be kept either in pellets, or in a large jar,
leaving it to dry.
But before removing the water, the whole should be strained
through a close horse hair sieve, resting the sieve on two sticks laid
across the jar into which it is to be strained, and stirring about the
thick liquid which is put into the sieve with a brush, that the fine
parts may pass through, and tapping it on the outside from time to
time, that the thick part which remains in the sieve may subside. And
after it has been all strained in this manner, it will be like milk ; it
should then be left to settle, then the lime water should be poured
off; preserving, however, enough for use, if you require it for any
purpose, and pour it off gently, that it may not mix with the lime.
But when it is required for use, the lime settled at the bottom of
the jar should be taken out with a large wooden spoon, aud then the
tints for the buildings, and other general tints, may be made of it in
the same manner as the tints are made for painting in distemper,
