WHAT ARE THE FIVE STAGES OF CLAY?
CLAY HAND BUILDING METHODS
Other Important Clay Terms:
What is a sculpture?
What does it mean to Slip and Score?
2D vs. 3D
* Shape has height and width
*Form has height, width, and depth
*Both are elements of art
*Relief Sculpture: Can only be viewed from front and sides; 180 degress
*In-the-round Sculpture: Can be viewed from ALL sides; 360 degrees
1. Plastic: Clay is wet; easily manipulated
2. Leatherhard: Clay is almost dry, but you can still carve into it
3. Bone Dry: Clay is completely dry; Very little carving possible; VERY FRAGILE!
4. Bisqueware: Clay has been fired ONCE; strong
5. Glazeware: Clay has been painted(glazed) and fired for a second time
Score and slip refers to a method of joining two pieces of clay together.
1. score the clay; this means that you make scratches in the surfaces that will be sticking together. Think of it like creating Velcro...
2. Add slip; You wet the surface with some slip (clay+water), using it like glue. Too much water may cause your piece to form major cracks in the clay. Too little water will be ineffective.
3. Press the two pieces together and weld shut.
It is very important to always score and slip clay that is leather hard. If you do not, the pieces will likely pop apart when they are fired.
*Kiln: Oven used for firing clay
*Firing: The process of heating clay to extreme temperatures to turn it into a hard material
*Glaze: A colored liquid that turns to a glass like surface when fired.
*Underglaze: A colored liquid made of clay, pigment, and water with a matte (flat) finish.
*Sgraffito: Italian for "To Scratch". A clay decorating technique created by scratching away layers of underglaze to reveal the color of the clay underneath
SPACE MOVEMENT CONTRAST RHYTHM LINE QUALITY
*Italian for "TO SCRATCH"
*Technique used to decorate clay to create strong CONTRASTING images.
*Uses the art elements LINE AND SHAPE in a variety of ways and patterns
APPLY UNDERGLAZE, let dry, scratch away!
THINK ABOUT THE FORM YOU WANT!
What do you want the function of you clay piece to be? What will be its purpose? Will it hold something specific? rubber bands? pencils? Will you drink/eat out of it?
Do you want the base to be circular, square, triangle? Other shape?
SLIP AND SCORE IS ALWAYS NECESSARY
Any time you join clay together. SLIP, SCORE, and smooth it all out!
This process would be the same for ANY shape you want to work with.
What SHAPE do you want your sculpture to be based on?
Square? Circle? Triangle? Organic shape?
2. What will your sculpture hold?
Office supplies, food, liquid, ect...
3. Make a LARGE sketch of your sculpture in your sketchbook. On your sketch, include designs you want to scratch into the surface for the sgraffito technique
(provide example on board)
