Marble
Chimney-Pieces.
Marble
chimney-pieces
may
also
be
rubbed
with
it,
after
cleaning
the
marble
with
diluted
muriatic
acid,
or
warm
soap
and
vinegar;
but
the
iron
or
brass
work
connected
with
them
requires
other
processes.
368.
Polished
Iron
Work
may
be
preserved
from
rust
by
an
inexpensive
mixture,
consisting
of
copal
varnish
intimately
mixed
with
as
much
olive
oil
as
will
giye
it
a
degree
of
greasiness,
adding
thereto
nearly
as
much
spirit
of
turpentine
as
of
varnish.
369.
Cast
Iron
Work
is
best
preserved
by
the
common
method
of
rubbing
with
black-lead.
370.
Rust.
If
rust
has
made
its
appearance
on
grates
or
fire-irons,
apply
a
mixture
of
two
parts
of
tripoli
to
one
of
sulphur,
intimately
mingled
on
a
marble
slab,
and
laid
on
with
a
piece
of
soft
leather.
Or
emery
and
oil
may
be
applied
with
excellent
effect;
not
laid
on
in
the
usual
slovenly
way,
but
with
a
spongy
piece
of
fig
wood
fully
saturated
with
the
mixture.
This
will
not
only
clean
but
impart
a
polish
to
the
metal
as
well.
371.
Brass.
Brass
Ornaments,
when
not
gilt
or
lacquered,
may
be
cleaned
in
the
same
way,
and
a
fine
colour
given
to
them,
by
two
simple
processes.
372.
First
Brass
Process.
The
first
is
to
beat
sal
ammoniac
into
a
fine
powder,
then
to
moisten
it
with
soft
water,
rubbing
it
on
the
ornaments,
which
must
be
heated
over
charcoal,
and
rubbed
dry
with
bran
and
whiting.
373.
Second
Brass
Process.
The
second
is
to
wash
the
brasswork
with
roche
alum
boiled
in
strong
ley,
in
proportion
of
an
ounce
to
a
pint;
when
dry,
rub
it
with
fine
tripoli.
Either
of
these
processes
will
give
to
brass
the
brilliancy
of
gold.
