Seed-Lac
Varnish.
Take
3
ounces
seed-lac,
and
put
it,
with
a pint
of
Bpirits
of
wine,
into a
bottle
of
which
it
will
not
fill
more
than
two-thirds.
Shake
the
mixture
well
together,
and
place
it
in a
gentle
heat
till
the
seed-
lac
appears
to
be
dissolved
:
the
solution
will
be
hastened
by
shaking
the
bottle
occasional
l3\
After
it
has
stood
some
time,
pour
off
the
clear
part,
and
keep
it
for
use
in
a
well-stopped
bottle.
The
seed-
lac
should
be
purified
before
it
is
used,
by
washing
it
in
cold
water;
and
it
should
be
in
coarse
powder
when
added
to
the
spirit.
This
varnish
is
next
to
that
of
copal
in
hardness,
and
has
a
reddish-yellow
colour
:
it
is,
therefore,
only
to
be
used
where
a
tinge
of
that
kind
is
not
injurious.

Shell-Lac
Varnish.
Take
5
ounces
of
the
best
shell-lac,
reduce
it
to
a
gross
powder,
and
put
it
into
a
bottle
in
a
gentle
heat,
or
a
warm,
close
apartment,
where
it
must
continue
2
or
3
days,
but
should
be
frequently
well
shaken.
The
lac
will
then
be
dissolved,
and
the
solution
should
then
be
filtered
through
a
flannel
bag
;
and,
when
the
portion
that
will
pass
through
freely
is
come
off, it
should
be
kept
for
use
in
well-
stopped
bottles.
The
portion
which
can
only
be
made
to
pass
through
the
bag
by
pressure
may
be
reserved
for
coarse
purposes.
Shell-lac
varnish
is
rather
softer
than
seed-lac
varnish,
but
is
the
best
of
varnishes
