2. Stages of Clay • Slip • Plastic • Leather hard • Bone Dry • Bisqueware • Glazeware Greenware

3. Slip Clay in liquid form. Slip is used as a glue to fuse two pieces of clay together.

4. Plastic Clay in work-able form. Plastic clay is clay straight from the bag that is molded or thrown on the wheel. It is soft and easy to work with.

5. Leather Hard Clay that has begun to dry and harden. Leather hard clay can be carved into, or shaped using tools. It is strong enough to withstand the pressure of the tools, but soft enough that it can still break with little effort.

6. Bone Dry Clay that is completely dry. When the clay is completely formed and carved, it is left out to dry for several days. When all of the moisture evaporates out of the clay, the clay turns to a light gray color, and is warm to the touch, it is bone dry and ready for firing.

7. Bisque ware Clay that has been fired in the kiln. When clay is fired, it is no longer called “clay” it is called “ceramic.” A bisque fire is the first time you fire your clay. Bisque ware is hard, solid clay- it will break if you drop it.

8. Glaze ware Clay that has been glazed, and fired a second time. Glaze ware is what we call a piece of ceramic that has been glazed and fired, again. Glaze is a paint-like substance made up of several particles, including glass, that melts when heated and as it cools, turns a color and solidifies.

9. The Kiln We use electric kilns where coiled wires bring up the heat (much like a large toaster ). They can go up to about 5,000 degrees. Both the inside AND the outside are extremely hot!

11. Lanterns… • What is a lantern? • a transparent or translucent, usually portable, case for enclosing a light and protecting it from the wind, rain, etc. • What are they used for? • a source of light, decoration, offerings.

12. Loi Krathong (Floating Crown) • A festival celebrated annually throughout Thailand and certain parts of Laos and Burma .

13. Jack-O-Lantern • A hollowed out pumpkin with a scary face carved into it with a light inserted into it to create a glowing face. These originated in Ireland and were used to ward off evil spirits on Halloween.

14. Japanese Garden Lantern • The Ancient Japanese used to make lanterns for their gardens as offerings to Buddah.

15. How to Make a Lantern 1. Form the clan into a softball sized ball 2. Cut the clay in half and form two equally sized/shaped pinch pots

16. How to Make a Lantern 3. Score the outter lip of both pinch pots using the scoring tool. 4. Generously apply slip to the scored edges.

17. How to Make a Lantern 5. Blend the two pinch pots together so the seam isn’t visible. You may need to add a coil reinforcement. 6. When leather hard, roll your egg to make the sides even.

18. How to Make a Lantern 7. Cut an opening at the top/bottom of your lantern and smooth out the edges. 8. Using a pin tool sketch your approved design into your lantern. 9. Using the xacto knife, pierce your design into the lantern.

19. Pierced Decoration When making the pattern, the parts of clay left between the holes must be strong enough not to break, the more spaces there are, the weaker it becomes. While cutting, support the piece from behind with your other hand or hold an object against it. If the cutting has left a rough edge, smooth it out with a wet soft brush.

20. You Will Be Graded On: The structure of your lantern: Did you follow directions? Can I see the seam? Is it symmetrical? Is it large enough? • The design of your lantern: • Is it interesting? • Is it clean? • Is it original? • Your effort & time management: • Is your project done on time? • Did you utilize every class period? • Did you use all tools properly? • Did you follow clean-up procedures? • The glaze application: • Is it even? • Does it have unity? • Does it add to or distract from your piece?
