Transcript of Clay Vessels
1. Pinch Method-forming clay from a single mass
2. Coil Method-using small snake-like coils to build shape gradually
3. Slab Method-using rolled slabs of clay to piece together shape
4. Thrown Method-using a rotating pottery wheel to form shape -Ceramics is the art of using clay to create sculpture or utilitarian objects.
-Clay is made up of sediments (dirt, minerals, etc) pressing into one another, held together by water. As clay dries, is goes through different stages in which the clay texture and consistency changes.
1. Wet Clay is when the clay is easily molded and changed with small amounts of moisture added to the already wet clay.
2. Leatherhard is the first stage of the drying process. The clay is still moist and can be worked with, but it also holds it shape so you can carve into the clay easily.
3. Bone-dry is the stage in which all moisture is gone from the clay and it is ready to be fired. Clay is extremely brittle in this stage.
4. Bisque is the last stage after the clay has been fired and is ready for glaze. Clay Vessels 26,000BC: Early man discovers clay, consisting of mammoth fat and bone mixed other materials. Then if molded and dried in the sun they discovered it was brittle and heat resistant. 6,000BC: Ceramic firing is first used in ancient Greece. The Greek pottery, Pithai, was developed and used for storage, burial and art. 4,000BC: Glass is discovered in ancient Egypt. This primitive glass was mainly used for jewelry, but we still use the glass coating on ceramic surfaces today for anything from bathtubs to airplanes. Lesson on Texture There are 3 main clay bodies:
1. Low Fire- Earthenware
2. Mid-Range- Stoneware
3. High Fire- Porcelain Element of Art: Texture Texture is used to describe either the way a three-dimensional work actually feels when touched, or the visual "feel" of a two-dimensional work. Clay Vessel Project: Objective: Students will create a clay vessel that exhibits texture and shows excellent craftsmanship, execution and creativity. Sketchbook Homework In your sketchbook create a series of small texture drawings in a 3x3 grid. Recreate physical textures into visual textures.
