| Demo notes: GP bowl |
Preparation | - wedge & knead 4 pounds of soft clay & divide it into 4 1-pound balls
- bat
- bucket 1/2 full of water
- throwing stick
- small sponge
- needle tool
- cut-off wire
- plastic sheet or clay bag for scrap clay
|
Pat down the clay | - Dry hands, dry clay
- Start the wheel turning very slowly
- pat clay down firmly onto the bat
|
Center the clay
| - Wet hands, wet clay
- Speed up the wheel (3/4 top speed on kickwheel; as fast as you can go on electric)
- Brace your elbows against your hips or thighs
- squeeze the clay from the sides up into a cone
- press the clay back down into a hemisphere (3x)
|
Open the
clay | - Slow down the wheel to medium-fast speed
- With fingers of left hand, make conical hole until clay at bottom is ¼ inch thick
- Make an undercut with left thumb outside bottom at 4 o'clock
|
Make the first pull
| - Slow wheel down to medium-slow speed
- Re-wet the clay and your hands before each pull
- Right hand outside, edge of hand against wheelhead at about 4 o'clock
- left fingertips inside at very center
- Left fingertips smoosh the clay up against right palm
|
2nd & 3rd & 4th pulls | - Start each pull at the very bottom on the outside and very center on the inside
pulls happen at about 4 o'clock, left fingers inside and right fingers outside- For each pull, left fingertips press outward against right fingertips
|
Finish & cut off
| - Remove excess clay at the base with the throwing stick; left fingers inside keep the clay from bulging inward
- use the throwing stick to smooth & clean slurry from the outside of the bowl
- Use a sponge to remove excess water from the inside bottom
- Dry hands & wheelhead
- Clean your wire
- Keep the wire taught and tight against the bat
- Pull wire towards you and follow through
- Let the bowl dry to leatherhard on the bat
|
Tips
| - The softer the clay, the easier it will be to center
- The more thoroughly you wedge your clay, the easier it will be pull up
- If you have lots of air bubbles in your clay, it needs to be kneaded more thoroughly
- wet your hands each time you touch the clay
