sometimes
called
plain
oclire,
and
the
latter
spruce
ochre.
It
will
grind
very
fine,
resists
the
weather
well,
and
bears a
good
body.
Massicot
is
a
good
light
yellow
for
general
use,
and
very
serviceable,
mixed
with
blue,
for
making
greens.
Chrome
Yelloio
is
a
very
rich
and
brilliant
yellow,
and
employed

Patent,
Yellow.
—
It
is
a
very
beautiful
colour,
much
in
use
among
coach-painters.
Orpiment.
—
It
is
good
for
some
purposes,
particu-
larly
for
the
production of
straw-colour
in
painting
doors,
windows,
&c.
It
likewise,
in
common
with
all
bodies
that
contain
arsenic,
produces
a
bad
effect
on
any
metallic
substance
exposed
to
its
action.
Naples
Yellow.
—
The
best
of
all
yellows.
It
is
milder
and
more
unctuous
than
either
orpiment,
massicot,
or
any
of
the
ochres.
It
is
necessary
to
use
it
with
great
care.
It
must
be
ground
well
on
a
slab
of
porphyry
or
marble,
and
scraped
together
with
an
ivory
knife,
as
both
stone
and
steel
have
a
tendency
to
turn
it
to
green.
Yellow
of
Antimony.
—
It
holds
an
intermediate
place
between
chrome
yellow
and
J^aples
yellow.
It
is.
chiefly
used
for
giving
a
yellow
colour
to
glass
and
earthenware.
Yellow
Pink.
—
It
grinds
and
dissolves
in
water
easily
;
but
care
must
be
taken
not
to
bring
it
in
con-
tact
v;ith iron,
as
the
astringent
principle
which
it
contains
in
abundance
instantly
dissolves
that
metal,
which
in
its
turn
destroys
the
clearneas
of
the
colour.

blue
colours
superior
to
this,
both
in
clearness
and
durability,
