  CONSTRUCTING A COILPOT  OBJECTIVE:  The student will learn how to use coil- building techniques to create a coil pot that incorporates variety and pattern within a cardboard form.
• 3.
  TYPES OF HANDBUILDING  HAND-BUILDING TECHNIQUES:  1. Pinch Method  2. Piece Mounting Method  3. Slab Method  4. Coil Method  ** Consideration must be given to the thickness of clay walls, moisture content and methods for joining clay.

  WHAT IS COILING? Coiling: A method of creating objects by building bottom and/or walls with even, rope like coils made from wedged clay.

  COILING – TheHistory…  Pottery is one of the oldest art forms that have come down to us.  Its evolution and development through the ages, in all geographical areas, has continued in almost unbroken progress.

  What is COILCONSTUCTION?  The ancient technique of building a coiled pot involves squeezing, squashing and smoothing the successive layers of coils into an even wall which tapers as it grows and encloses a shape.  To do this you need to turn the pot around slowly as you work.
• 7.
  COILING – TheHistory…  Early potters soon learned to make the task of periodically turning the pot much easier and more efficient by beginning their coiling on a dish or bowl they could twist round as they worked.
• 8.
  COILING – TheHistory…  Eventually a small turntable or "tournette" was developed.  With this a pot could be turned around much more easily and quickly.  The pot making technique in Mesopotamia now gradually changed as the more potters adopted the turntable for making and decorating.
• 9.
  COILING – TheHistory…  However, it took a long time for free running steady turntables to be developed, therefore "throwing", as we understand the technique today, did not develop for a long time to come.  It would be more accurate to describe this turntable making process as "fast coiling."

  What are COILPOTS and who made them? Some examples of early coil pots made in Mesopotamia – Modern day Iraq.

  CREATING AND USING A FORM

  What do youneed to do?  Draw 3 sketches of coil pot designs.  Student and teacher will critique coil designs.  Select one design for the coil project.  Use variety and pattern in the construction of the coil pot.  The students should pre-plan the pot through drawings.  The students will correct mistakes in moisture levels of the clay or start over.  The construction of the pottery should complement the design and glaze – kiln procedures.  Demonstrate mastery of coil building.  Show evidence of craftsmanship.

  GENERAL BUILDING INFORMATION:  Makea base within your geometric form.  The first coils should be placed directly on top of the base and reinforced on the inside by a smaller coil.  Knead first coil to base, after that every three coils can be kneaded.  The use of slip between coils should prevent splitting at coil joints during firing.
• 19.
  GENERAL BUILDING INFORMATION:  Coilsshould decrease in size as the pot is created. Thicker coils on the bottom will support the weigh of the thinner coils at the top.  Smoothing inside should be determined by design and function.  Avoid accessive pressure when smoothing the inside of the piece, you want the design to remain against the form.
• 20.
  GENERAL BUILDING INFORMATION:  Thecoils themselves can be used as built- in decorative surface by making swirls, holes, bumps, or by varying the height of the coils.  Do not try to join wet clay to dry clay – start over!  Dry the pot slowly to prevent cracking or coil separation.
