Why Your Pot Keeps Collapsing on the Wheel

Common causes of collapsed pots and how to strengthen your throwing technique.

It happens to almost every new thrower — the pot starts off well, then suddenly sags, wobbles, or folds in on itself. Don’t panic. It’s part of learning.

Here’s why pots collapse — and what to do about it:

1. Your Clay Isn’t Centred
Even a slightly off-centre mound can cause uneven walls. Revisit centering basics until the clay spins true.

2. Walls Are Too Thin
Pulling the clay too quickly or too far thins out the walls. Aim for even thickness, especially near the base.

3. Too Much Water
Using excess water softens the clay. Keep your hands damp, not dripping, and sponge the wheel head regularly.

4. Wheel Speed Is Too Fast
When you go too fast, the clay can’t support itself. Use a slower speed once the form begins to rise.

5. Clay is Overworked
If you’re reshaping too much, the clay loses structure. Sometimes the best fix is starting over with fresh clay.

Final Tip
Collapse isn’t failure — it’s feedback. Learning to read the clay takes time, pressure, and patience.
