Ceramics 2: In Case you missed it...

- Clean up is key! Clay dust can build up and make a messy, less safe environment
- All clay goes into the proper Reclaim Bin. Check your clay!
- Clay must be wedged in order to use it.
- Do not make clay dust go airborne (clapping dusty hands, etc.) That is NOT SAFE.
- Do not eat near clay and always wash your hands first. Do not have an open beverage near clay/glazes.
- Don't poke one another with tools or spray one another. Come on now....
- NO CLAY IN THE SINK. ONLY DUSTY HANDS OR TOOLS THAT NEED WASHING.
- Understand the proper use of all tools (especially sharp tools).
- Keep all tools and equipment in good working order.
- I will be giving you a new handout like the one in Ceramics 1 but with more tools labeled for you.
1. Clay is plastic when sufficiently wet.
2. Clay shrinks when it dries and it vitrifies in the kiln by about 10%
3. Clay of very different water content and type can't be joined together. (bone dry + plastic)
4. Clay walls of different thickness shrink at different rates and this may cause cracking.
5. Clay hardens as it dries.
6. Non-shrinking materials can't be used as support

1. Hand building: includes pinch pot, coil, slab, slump and hump molds and modeling.
2. Potters wheel: equipment used by artists which spins to create cylinders of various kinds.
3. Molds: liquid clay called slip is poured into an existing mold shape.
1. Read assignment sheet carefully
2. Brainstorm
3. Choose an idea (must meet requirements)
4. Make sketch and construction plan
5. Plans must be approved by Mrs. Sexton
6. Get building
7. Carefully store between work periods
8. Keep covered until leatherhard
9. Leatherhard: underglaze or sgraffito if desired
10. Let it dry by laying plastic over it until bone dry
11. Bisque fire
12. Glaze DURING NEXT PROJECT CREATION PERIOD
13. Glaze fire
14. Hand in project AND COMPLETED PLANNER sheet
15. Take home
- When connecting VERY PLASTIC CLAY, all you really need is pressure.
- When connecting PLASTIC CLAY, all you really need is moisture and pressure. (MUST HAVE HIGH PLASTICITY)
- ANYTHING ELSE NEEDS TO BE SCORED AND SLIPPED
- Clay likes pressure during creation but does not like tension now or later.
1. Wedge clay on covered desk to eliminate air bubbles (clay will dry out while wedging on plaster).
2. Always join clay appropriately! Attaching large areas (laminating) is not a good idea.
3. Hollow any piece larger than your thumb.
4. Pieces in progress should be wrapped in a wrapped in ziploc or thick plastic bag. As you want the clay to dry, wrap accordingly.
5. Smooth/clean up surfaces! It is better to take care of any rough spots or hard edges before firing.
6. Your initials or name must appear on the bottom.
