tlie
copperas
kills
the
logwood,
and
so
renders
it
un-
fit
for
the
next
pieces.
It
is
frequently
the
case
that,
instead
of
the
first
process
of
sumach-boiling,
they
collect
the old
sumach,
and
fustic,
and
logwood-
liquor,
that
has
no
copperas
or
lime
in
it,
into
a
large
tub,
and
all
the
pieces
that
are
spoiled
in
the
other
colours
they
throw^
into
this
tub,
and
let
them
lie
a
few
days
till
they
are
ready
to
dye
blacks,
and
this
answers
instead
of
the
sumaching.
For
the
foregoing
cotton
shades,
the
pieces
are
first
taken
and
boiled
in
a
wood
or
copper
cistern,
as
circumstances
may
be, in
order
to
take
out
the
sizing,
and
prepare
them
to
receive
the
dye.

Gloss

Take
a
fair
white
potato,
cut
it
in
very
thin

take
out
the

run
your
silk

this
water,
squeeze
out,

you
will
have
a
very
superior

It
was
tried
on
black
silk,
and
it
was
found
to
answer
well.
If
it
should
not
answer
on
lighter
colours,
try
the
follow-

Anotjier
way
to
put
a
Gloss
on
Silk.
Instead
of
a
potato,
use
a
small
quantity
of

glass;
dissolve
in
water.
Use
it
the
same
as
the
above
in
every
particular.
1
ounce
of
isinglass
will
answer
for
1
pound
of
silk.
