# Taking It Further

You have your basic form open, now let's refine it and avoid the most common problems.

## Even Walls

The goal is walls that are the same thickness all the way around and from bottom to rim. To check:

*   Hold the pot up to a light source and look through the walls. Thinner spots let more light through.
*   Gently squeeze around the outside: you can feel thick and thin spots.

When you find a thick area, pinch just there. When you find a thin area, leave it alone.

## Cracks at the Rim

The rim almost always wants to crack. This is because it gets thinner and drier faster than the rest of the pot.

**The Fix**: Dip a finger in water and smooth the rim regularly. Never let it dry out. You can also compress the rim between two fingers at regular intervals.

## The Flat Bottom Problem

Round-bottomed pots tip over! To flatten the base:

*   Set the pot down on the table and gently press the bottom flat.
*   You can also paddle the base softly with a small flat tool.

## Surface Cracks While Pinching

If you see hairline cracks forming on the surface, the clay is drying too fast as you work.

**The Fix**: Work more quickly, or cover the pot with plastic for a minute to let the surface re-hydrate slightly.

## Upgrade Drill

Make three pinch pots in one session:

*   Pot 1: focus on even wall thickness.
*   Pot 2: focus on clean rim compression.
*   Pot 3: focus on shape control and stable base.

Target one skill per pot and improvement accelerates fast.

## Pro Tip

Two pinch pots joined rim-to-rim make a hollow sphere: the starting point for animals, rattle beads, and closed forms!

## Go Deeper

Joining two pinch pots rim-to-rim requires [slip](https://en.wikipedia.org/wiki/Slip_%28ceramics%29) as a bonding agent, the same liquid clay used in all handbuilding joins. The light-test for checking wall thickness relies on the [translucency](https://en.wikipedia.org/wiki/Translucency) of thin clay, a property that porcelain potters exploit deliberately in their finished work.

## Check your understanding

### Question 1: What causes cracks at the rim of a pinch pot?

- [ ] A. Pinching too slowly
- [ ] B. Too much water
- [x] C. The rim thins and dries faster
- [ ] D. Bad clay quality

Tip: The rim gets thinner and dries faster than the rest of the pot, causing it to crack.

### Question 2: How can you check if your pinch pot walls are even?

- [ ] A. Weigh it on a scale
- [x] B. Hold it up to light and feel the walls
- [ ] C. Ask someone else to look
- [ ] D. Tap it with a tool

Tip: Hold it up to a light: thin spots let more light through. You can also feel for thick and thin spots by squeezing gently.

### Question 3: Your pinch pot keeps tipping. What is the best correction?

- [ ] A. Thin the walls at the rim even more
- [x] B. Gently flatten and true the base
- [ ] C. Add a thick glaze foot
- [ ] D. Dry it faster under heat

Tip: Gently flatten and stabilize the base while the clay is still workable. A stable base prevents wobble and distortion later.
