Weigh and bag a set of throwing balls
Production potters pre-weigh all their clay before a throwing session. You should too.
The task
- Weigh out five balls of clay at exactly 300 g each
- Pat each into a smooth sphere (no cracks, no seams)
- Wrap each tightly in plastic and press out all the air
- Label with weight and date
48-hour test
Leave them wrapped for 2 days, then unwrap and check. The clay should be:
- Still soft and workable
- Same moisture level as when you wrapped it
- No dry edges, no mold
This is the foundation of consistent throwing. Same weight = same size pots.
