Ceramics 1 Pretest Notes

1. Ceramics 1 Pretest Notes

2. Attention!!! • There will be a test over this information that you must pass with a 75% before you can work with clay.

3. Complete the questions from the textbook first • 1-12

4. Wedging • How to wedge clay

5. From the teacher: • 1. Dry clay goes in a bucket because it is recyclable. • 2. Wet clay goes in a bag. • 3. Slip is liquid clay.

6. Take the terms I will show you and write them down in your own words. Make sense of it using things you already know about. Sketch it out. Do not copy the screen. • Funny example (but the wrong answer)-“The math teacher saw that Larry wasn't paying attention in class. She called on him and said, 'Larry! What are 2 and 4 and 28 and 44?' Larry quickly replied, 'NBC, FOX, ESPN and the Cartoon Network!' “

7. 4. The 6 stages of clay and describe • Wet • Leatherhard • Bone dry • Greenware • Bisque ware • Glaze ware

8. Wet clay • Working with really wet clay

9. Leatherhard clay • Working with leatherhard clay

10. Bone dry clay: completely dry

11. Greenware: Unfired pottery or sculpture

12. Bisqueware: clay that has been fired once in the kiln and is now ceramic

13. Glaze Ware: ware that has been fired with glaze

14. 5. Wedging: a way of improving the workability of clay by reforming the mixture to make it homogeneous and even in texture while eliminating air bubbles. • Wedging clay

15. 6. Once clay has been fired to over 1115 degrees F, it becomes ceramic. • It can never be clay AGAIN! • Discuss #7 on the page.

16. Tools • Bat: two meanings • The plaster is porous, and soaks up the physical water from the clay. I will allow enough water to be drawn out of the clay so that it is once again useable, or plastic, capable of being shaped on the potter’s wheel.

17. Cutting wire: a wire used for cutting clay

18. canvas • Cover the board or table with canvas so the clay won’t stick to it.

19. Slab strips • To help you roll out a slab that is an even thickness

20. Rib or kidney • Used for hand- building or wheel throwing to smooth and shape clay, made of wood, rubber or metal

21. Potter’s needle • Use it for scoring clay or for cutting off the rim of a pot on the potter’s wheel. One of the primary uses of the potter's needle is to get an accurate measure of how thick a slab or the floor of a pot is. • It is not a pencil! Clay is not paper! It is also not a shank.

22. Modeling tools • These tools are very useful for creating smooth edges, or curves on items to be modeled.

23. Loop tools • For carving and removing clay

24. Fettling knife • Mainly used for cutting slabs of clay

25. Stamps: used to make impressions in clay

26. Slip trailer or underglaze applicator • Slip Trialing demo • You can create these • decorations with glaze or • well blended slip.

27. Slab roller • How to use a slab roller

28. Potter’s wheel • A potter's wheel is a machine used in the shaping of round ceramic ware. The wheel may also be used during the process of trimming the excess body from dried ware and for applying incised decoration or rings of color.

29. Splash guards • It keeps the extra water from going everywhere when you throw.

30. Wooden paddle: the wooden paddle is an inexpensive wood tool designed to shape clay leaving a smooth texture behind.

31. Banding wheel: a wheel head mounted on a pedestal base and turned by hand, used in the formation and decoration of pots. • Using a banding wheel to glaze

32. Pug mill: A pugmill is a fast continuous mixer used for recycling clay.

33. Wedging table: a table covered with canvas and/or plaster used for wedging clay

34. 5 hand-building methods • Pinching • Coiling • Slab building • Drape molding • Press molding

35. Pinching: a hand-building technique that involves squeezing the clay, usually between fingers and thumb. • How to make a small pinch pot bowl

36. Coiling: attaching rolls of clay together to form pottery • Rolling coils

37. Slab building: hand-building technique that involves shaping clay into a broad, flat, thick piece. Like rolling out and cutting cookie dough. • How to roll out a slab by hand

38. Drape molding: using a drape mold to hold the clay slab in a certain shape until it stiffens

39. Press molding: making shapes by pressing the clay slab into or onto molds.

40. Glazing Techniques

41. Brushing: applying glaze with a brush-needs 3 coatsDipping: a method of applying glaze or slip to a piece by immersing it and quickly shaking off the excess liquid. This applies 3 coats.

42. Pouring: pouring glaze onto or into a pot. This method is great for the inside of a pot. This applies 3 coats. .

43. Sponging: applying glaze with a sponge.Slip trailing: applying glaze or slip with a slip trailer to make fine lines or dots

44. Spraying: Using a spray gun and spray booth to apply glaze. It applies a fine, even coating of glaze.There will be safety instructions for this later.

45. Firing • Bisque firing- Cone 05, temp= 1886° F • Glaze firing- Cone 6, temp=2266° F • Put wax resist on the foot of the pot. • Before bisque firing, the ware must be in what condition? __________ • Glazes can be clear, transparent, semi-transparent, semi-opaque, or opaque. • See next slide for examples

46. Clear • Transparent • Semi-transparent • Translucent • Semi-opaque • opaque
