Lumps
of
clay
are
measured
on
the
when
specific
/
equal
amounts
of
clay
are
needed
,
(
creating
multiples
of
the
same
size
item
)
and
is
done
to
improve
clay
consistency
/
remove
air
bubbles
A
ball
of
clay
is
centred
on
the
pottery
.
Ceramicists
use
their
hands
,
throwing
tools
,
ribs
and
rubber
kidneys
,
to
bring
shape
to
the
form
and
smooth
the
surface
.
This
is
called
.
A
is
used
to
add
or
remove
water
and
smooth
the
surface
.
It
is
important
to
compress
the
rim
of
the
form
this
can
be
done
with
fingers
,
or
a
piece
of
leather
.
A
is
used
to
cut
the
clay
at
the
base
of
the
form
,
after
wiring
off
,
pieces
made
on
a
separate
can
be
left
on
it
to
become
dry
enough
for
Work
can
be
placed
back
on
the
wheel
and
turning
tools
including
loop
tools
and
stem
tools
can
be
used
to
removes
excess
weight
,
refine
the
shape
,
and
add
foot
rings
by
turning
clay
from
the
base
.
There
are
different
examples
of
Hand
building
.
When
Clay
is
squeezed
between
fingertips
to
create
the
required
shape
,
it
is
called
.
When
clay
is
rolled
out
and
cut
to
the
required
shape
,
and
stiffened
pieces
are
joined
using
scratch
and
slip
method
to
create
the
form
it
is
called
Building
.
When
Coils
are
made
by
hand
(
rolling
)
or
machine
(
)
and
used
to
create
the
form
,
it
is
called
.
Most
of
the
time
the
surface
is
smoothed
out
by
hand
but
sometimes
coils
are
left
visible
.
When
making
a
out
of
plaster
.
the
item
to
be
cast
is
prepared
,
using
clay
to
avoid
,
and
usually
in
a
temporary
frame
of
Boards
the
plaster
is
poured
on
,
producing
a
reverse
of
the
item
.
Oil
or
soft
soap
is
used
on
the
item
being
cast
and
on
the
plaster
if
more
plaster
parts
are
to
be
poured
(
more
than
a
one
piece
mould
)
,
to
allow
separation
and
release
after
the
mould
is
made
.
A
Cottle
can
also
be
a
cylindrical
tube
sealed
with
clay
around
the
base
and
held
around
the
height
with
string
or
duct
tape
to
avoid
leaks
.
Pouring
(
liquid
clay
)
into
a
plaster
mould
to
recreate
the
internal
form
is
called
Slip
-
The
clay
forms
a
skin
as
it
dries
against
the
plaster
and
the
excess
slip
is
poured
out
when
the
of
the
skin
is
enough
.
The
clay
is
then
dried
in
the
mould
,
until
it
is
safe
to
take
out
(
typically
an
hour
)
at
this
stage
they
can
be
joined
on
to
other
pieces
using
the
and
method
.
The
surface
is
refined
and
the
seams
from
slip
cast
forms
are
removed
,
in
a
process
called
.
Clay
at
this
stage
is
called
greenware
and
is
still
able
to
be
recycled
.
