  • Clay isa product made from earth and water and when heated it becomes hard. WHAT IS CLAY? • It is made up of very thin soil particles which becomes plastic when wet and very hard when dry. Plasticity: when the tiny soil particles are wet and stick together so that the clay can be molded (shaped by hand).

  WHAT IS CERAMICS? •Ceramics is the general term for clay objects that have been fired to change it to a permanent hardened state.

  • Is alsoknown as the Pinch pot technique/method. 1. Pinching Technique • This technique is a very simple technique. How to make a Pinch pot 1. Roll a lump of clay into a ball using both hands so that it fits in the palm of the hands. 2. Holding the ball of clay in one hand, push the thumb of the other hand into the middle of the ball and press into it to open a hole in the middle leaving about 1/4˝ - 1/2˝ thickness at the bottom. 3. With the thumb inside and the other fingers outside start by gently pinching the sides of the clay from the inside with your thumb against the fingers on the outside to form the shape you want and leaving about 1/4" thickness at edge.

  2. Coiling Technique •This technique involves attaching rolls of clay called coils one on top of another to build bowls, vases and other ceramic forms in various shapes and sizes. 1. Flatten a piece of clay to about ¼” thickness using a rolling pin to make the base of the pot.. Use a knife or needle to cut out the shape of your base 2. Prepare clay coils by squeezing a small ball of clay into a sausage shape. Roll the clay sausage on the table using the whole length of your two hands, from fingertips to wrist. Spread your fingers out and move your hands from the middle of the coil outwards. Roll even coils of a reasonable length. How to make a Coil pot

  3. Using asharp tool, score the base and add some slip to it. This acts as a glue and will make the surfaces stick together 4. Cut a coil the length of the base shape by first lining it up on the base. Lay the coil down onto the base and gently press the two surfaces together so that they bond. 5. With the coil in place, use the thumb or a modelling tool to blend the clay coils together to make the walls stronger. (The fingers make it smoother). When the surface is blended, you loose the coil design. So if you want the coils to be visible on the outside you should blend the surface on the inside of the pot. How to make a Coil pot (Cont’d)

  3. Slab methodTechnique • Slab building method involves the rolling out of clay to an even thickness creating slabs and then cutting shapes and joining the clay together to form a finished product.
• 11.
  1. Place alump of clay on the work table and flatten it down a little using the heel of the hand. This will make the job of rolling easier. 2. With a rolling pin and two roller guides (one on either side of the clay) begin rolling out the slab. This is to get it rolled evenly with equal thickness through out. Roll the slab in one direction. Then pick it up and turn it around and continue rolling in that direction. • After the slap is prepared, you can cut pieces to create an object (pot, vase etc.). A slab pot can be made out of one single clay slab by draping a single clay slab over or into a mold to create the shape of the mold OR a few pieces can be cut out of the slab and joined together to make a more angular piece.

  3. Using papercreate a template which will used as a guide to help cut out the pieces so that they are the right size and shape. This process is best done when the clay is leather hard. 4. Once the pieces are cut out of the clay they are then joined together to create the pottery. The edges are first scored and slip is applied. The slabs are then joined together. A small coil is added along the edge where the edges join and a smooth tool is used to blend it in to help reinforce the edge. Once the slab pot is finished, the clay surface is tidied up using a rib tool. How to make a Slab pot (Cont’d)
