Equipment needed: Enough clay for each student to create at least one small project. If you absolutely have no money, use a homemade Salt/Flour/Water dough.Clay tools for blending, assorted forks, knives, pointed sticks or pin tools

to manipulate and trim clay Plastic bags with ties for storing pieces until they are ready to dryPlastic sheeting to protect table tops Covered air-tight containers for clay storage

Clay is one of the three main kinds of soil, the other two being sand and loam. http://www.florence.ars.usda.gov/kidsonly/element/ka2.htm

Most soils of agricultural importance are some type of loam. A certain amount of clay is good because it helps hold particles together and helps hold water. If soil has a lot of clay it is difficult to cultivate. The stiffness resists agricultural tools, interferes with the growth of the plants, and prevents free circulation of air around the roots. Clay soils are cold and sticky in wet weather, while in dry weather they bake hard and crack. Clays can be improved by the addition of lime, chalk, or organic matter. In spite of their disadvantages, the richness of clay soils makes them favorable to the growth of crops that have been started in other soil.

Ancient man discovered that clay could be shaped and modeled into forms both decorative and functional.

Some of the earliest pottery has been found in the Middle East and dates to between 8,000-7,000 BCE.

Japanese ceramics have flourished since over 4,000 years agoNative American pottery shards have been found dating back over 3,000 years.

Students will learn that clay is mentioned in the Bible 39 times and read these

scriptural quotations (these will be on a separate handout)

Students will discuss commercially made ceramics in everyday life http://www.kyocera.co.jp/frame/product/ceramics/fc/index-e.html

Students will view some contemporary ceramic sites http://www.claywork.com/

Page 10: Basic Ceramics1

Students will be given a small amount of clayTeacher will demonstrate how to wedge the clay using the “ram’s head” technique

Page 11: Basic Ceramics1

Teacher will explain that it is not like kneading bread dough which puts air into the dough

Students will wedge the clay until the air bubbles have been removed Students will learn to use the wire cutting tool to check for air bubblesTeacher will lecture and demonstrate as the students follow along if the room

arrangement will allow, otherwise the students will gather around the teacher for the demonstration and go back to their seats to do the same.

Page 12: Basic Ceramics1

Students will learn that there are various states of clay

Leather-hard The condition of a clay body when much of the moisture has evaporated and shrinkage has just ended, but the clay is not totally dry. Carving, burnishing, or joining slabs are often done at this stage.

Bone DryClay that has the moisture completely evaporated. It can no longer be scored and slipped without compromising the strength of the piece.

BisqueClay that has been fired to a state hard enough for glazing

SlipClay suspended in water. When it is a yogurt consistency it can be used to join pieces with scoring. When a cream consistency with a coloring agent added it can be painted on leather-hard pieces and burnished.

Greenware Unfired pottery or sculpture.

Students will squeeze or roll the clay between your hands into coils about ½

inch in diameter (a little thicker than a pencil).

Page 14: Basic Ceramics1

Students will take the coil and create a tight flat spiral that will be the base of the piece

Students will blend the spiral coils together so that it is flat

Page 15: Basic Ceramics1

Students will add another coil to the outer edge of the base Students will add additional coils on top of that in order to build up height

Page 16: Basic Ceramics1

Students will blend both the inner and outer surfaces of these coils This can be more easily done if done every few added coils

Page 17: Basic Ceramics1

Students will learn that the more time and effort they take in blending the coils, the stronger the piece will be, and that they cannot simply be pressed together

Page 18: Basic Ceramics1

Students will keep adding new coils until the piece is as tall as they want

Page 19: Basic Ceramics1

Students will carefully blend the coils together for strength.

Page 20: Basic Ceramics1

Students will continue to build, adding coils and smoothing them as they goStudents will make sure to keep their work wrapped securely in plastic to

prevent pieces from drying

Page 21: Basic Ceramics1

Turning the pot over carefully is a good way to make sure the top edge is straight across

A paddle or stick can be used to even up lopsided potsCarving tools can be used to clean up the edges for a finished look

Page 22: Basic Ceramics1

One side of this bowl has been stained and scratched intoThe other side has been scratched into and had stain rubbed into the grooves. It was bisque fired a shiny black glaze was applied to the outside An aqua underglaze was applied to the inside and coated with a clear glazeIt was cone fired to complete the process

Page 23: Basic Ceramics1

Students may add textures and other decorative touches to the workOnce the piece is done it may be driedDried pieces may be carved, painted, or decorated with other media if desired

Now THIS is a great coiled pot!This was made by another UWM student in my class

Page 25: Basic Ceramics1

This is how it looked after firing, but unfortunately he dropped it on the floor.It broke into quite a few pieces. In ceramics as in life, bad stuff can happen.But look at this other one! It is three times larger!It was made by the same student in my UWM class.
