  1. CERAMICS- VOCABULARY Sossaman Middle School Mrs. Breckenridge

  2. Plan • Today- PowerPoint, notes, tool review (hover cam) • Thursday- Create base, stamp base • Friday- As a class we will roll coils and start your coil pot • Monday- Review, mini quiz, work day • Tuesday- Show how to smooth coils properly • Followed by work days (determined by class)

  3. Ceramics • The art of making things out of clay.

  4. Clay • A naturally occurring material composed primarily of fine-grained minerals. Organic materials which do not impart plasticity may also be a part of clay deposits.

  5. Can you name the stages that clay goes through in order?

  6. Stages of clay • Slip- half water half clay • Wet clay • Leather hard • Bone dry • Bisqueware (when it has been bisque fired) • Glazeware (when it has been glaze fired, it is now a completed artwork!)

  7. Leather hard • This is the stage when some of the water has dried out of the clay. It is still a little bit pliable but it will break if you try to fold it. • This is a good time to draw, carve, or scratch designs or words into your clay.

  8. Bone dry • This is when all of the moisture is dried out of the clay. • This is when it is ready to be bisque fired. • Bisque fire- is the first fire. It has to be bisque fired before it can be glaze fired.

  9. Bisqueware • This is when it has been fired for the first time. It becomes very strong after the bisque fire and it turns white. It is now ready to be glazed. • A bisque fire is done at a lower cone (temperature) than a glaze fire • This firing is done at Cone 04

  10. Glazeware • This is when your project has been glazed and glaze fired. Your ceramic project is now complete. • There are a wide variety of glazes including underglaze, overglaze, high fire glaze, and low fire glaze. We will be using low fire glaze. I bought a wide variety of colors! • This firing is done at Cone 05-06 for our low fire glazes

  11. Wedge • Method of kneading clay to get rid of air pockets in the clay. • Why is it important to get all of the air pockets out?

  12. Wedge • Method of kneading clay to get rid of air pockets in the clay. • Why is it important to get all of the air pockets out? • Answer: The culprit is too much moisture in your greenware. At 212°F degrees water turns into steam. The pressure from the steam, and nowhere for it to escape, causes the piece to explode. If there’s too much moisture in your greenware, especially moisture inside hollow air pockets within the clay, you run the risk of having your greenware explode. (claygeek)

  13. Can you name some ways to prevent projects from exploding in the kiln?

  14. Some ways to prevent explosions • Air dry projects for as long as possible (you) • Create a hole in hollow forms for steam to escape (you) • Don’t build thicker than 1 inch (you) • Fire using a long preheat (me) • Fire Slow (me) • Go teamwork!

  15. Can you name some different types of building?

  16. Hand Building • Pinch • Slab • Coil • Throwing on the wheel

  17. Score and Slip • This is a technique used to attach two pieces/bodies of clay together. • Score- when you make marks in your clay, this helps the clay hold/fuse together • Slip- This is your glue- it is clay

  18. Potter’s Wheel • A machine that spins a BAT at different speeds so that you can make a more even bowl, vase, teapot, or other ceramic vessel. • What is a bat?

  19. Potter’s Wheel • A machine that spins a BAT at different speeds so that you can make a more even bowl, vase, teapot, or other ceramic vessel. • What is a bat? A bat is the tray that you will put your clay on when you use the wheel.

  20. Clean Up Procedures • Return all supplies to the bins and return the bins to their cabinet. • Wipe any extra clay scraps into your hands and put them into the slip cups. • Use a sponge WITH THE WATER SQUEEZED OUT to wipe the table. • Do a final wipe down with a wipe. If we do not have wipes get a paper towel or a very clean sponge, get it wet, then wipe the table down again.
