Before Class:
- Have students prepare temper before class

- After clay is fully dried, prepare watermelon tub
- Add sawdust to kiln
- Using a twisted piece of newspaper or a safety lighter light a section of the sawdust on fire
- Allow the fire to spread throughout the tub, agitate with a stick if necessary
- Wrap dried clay pieces individually with newspaper

- Use a spray bottle with water to keep clay moist during hand-building
- Keep loose scraps of excess clay for another project
- Use a wire clay cutter when sectioning of clay pieces
