CERAMIC MUG

1
CERAMIC MUG

• Slab and sculptural construction

2
Create a functional ceramic mug with at least
one sculptural form incorporated in the design.

• Mug will be built in 4 parts-body, bottom, handle
  and sculpture.
• Mug will be built mainly in a slab construction.
• Mug must be functional-meaning you can drink out
  of it.
• Sculptured object should be either on the
  exterior, interior or handle.
• All ceramic structural guidelines must be met.(
  see handout )
• Mug must be well crafted.
• Fired must be glazed and fired a second time.

CERAMICS ceramics- the art of making functional
clay objects by firing at high temperatures

• Greenware clay must be pounded and kneaded before
  use. This removes air bubbles which prevents
  explosions. All parts of the clay object must be
  no thicker than your thumb. If it is thick you
  must hollow out the clay.
• Cover table with a tablecloth and place clay on a
  canvas board.
• Work clay into forms with hand building methods
  or tools
• Air will dry out the clay. Always cover your clay
  object in a plastic bag unless it is a 100
  complete. If the clay starts to become dry or
  cracks spray object with water. If it becomes
  very dry cover clay with a damp (NOT wet) cloth.
  Place clay object back in a bag and let the clay
  absorb the water from the cloth overnight.
• The best way to add appendages such as handles,
  spouts, etc. is using leatherhard clay. Clay will
  naturally get leatherhard over time but you can
  quicken the process by puffing up a bag with a
  lot of air and closing the bag with the air still
  in there.
• You must slip and score all clay pieces together.
  If you skip this process the pieces you attach
  may fall apart. When clay dries it shrinks
  because it is losing water. As the pieces shrink
  they will naturally want to pull apart from each
  other.
• When you are finished creating your object you
  must let the clay become bone dry. Remove bag and
  put the object in the kiln room and let air dry
  on the bisque fire cart. The piece will take
  several days to be dry enough to fire.
• When the object is bone dry it is then bisque
  fired in the kiln for about 8 hours. After it is
  fired the surface of the clay will be white, hard
  and chalky.
• You may now paint or glaze the object. After the
  object is glazed it must be fired a second time.
  When the object has been glazed the surface will
  be shiny, smooth and functional.

Ceramics overview cont

• Greenware- damp clay before firing.
  Leatherhard-clay that is still damp but still
  enough to hold its form. This is the best
  condition to trim, carve and add appendages.
  Slip and score-process used to adhere clay
  together.Slip is a clay and water mixture that
  act like a glue. Using a fork scratch both
  surfaces that are to be joined. Place slip on one
  of these scored areas and blend pieces together
  with a tool. When you are done there should be no
  visible lines between the pieces of clay. Bone
  dry-clay that is ready for firing. It is very,
  very fragile at this point. Kiln-oven used to
  cook clay where temperatures reach 2000 degrees
  F. Bisque-clay that has been fired once.
  Fire-when clay is cooked in the kiln. This
  process hardens, strengthens clay and adheres
  glazes. Glaze-a liquid that is painted on a
  ceramic piece to seal the porous surface and add
  color. ( see glaze handout for more info).

A SLAB of clay is a thin wall of clay that can
formed into a variety of forms including a
cylinder.AN EVEN SLAB CAN BE ROLLED OUT WITH
SLAB ROLLER OR ROLLING PIN
