# Building the Seat Into the Pot

A gallery is a ledge thrown into the inside of a pot's rim. It is the seat the lid rests on. When you throw a gallery into a pot, you are building a precision fit directly into the vessel, and that demands a steady hand and the right technique.

## What a Gallery Looks Like

Imagine looking down into the top of a teapot or canister. Inside the rim, there is a small horizontal step, about 1cm wide. The lid rests on this step. From outside, the pot looks normal. From inside, there is this neat ledge.

## Throwing the Gallery

The gallery is formed while the pot is still on the wheel, immediately after throwing the walls.

1.  **Slow the wheel** to medium-low.
2.  **Place two fingers** (index and middle) inside the rim, positioned at the depth where you want the gallery to sit, typically 1–1.5cm below the top of the rim.
3.  **Press outward** with those two fingers while your outside hand supports the wall. This pushes clay outward to form the horizontal shelf of the gallery.
4.  **Define the inner wall**: The inside edge of the gallery should be vertical and clean. Use a finger to compress and define this inner step.
5.  **Measure the gallery opening**: Use your caliper to measure the inner diameter of the gallery. This is the measurement to throw the lid to.

## The Gallery Rim

The outer rim above the gallery can be left straight, or slightly flared outward; this gives visual elegance and provides a guide for placing the lid.

## Pro Tip

Throw the gallery slightly deeper and wider than you think necessary. Clay is much easier to remove later than to add back.

## Gallery Quality Check
After throwing the gallery:
* Inner gallery wall is clean and vertical
* Shelf is wide enough for stable seating
* Caliper measurement captured immediately

These checks save hours of lid adjustment later.

## The Bigger Picture

The gallery is a precision feature that demands the same careful measurement with a [caliper](https://en.wikipedia.org/wiki/Caliper) as any other lid-fitting detail. In the [Japanese tea ceremony](https://en.wikipedia.org/wiki/Japanese_tea_ceremony), lidded vessels like the mizusashi (water jar) rely on gallery fits that are snug yet easy to open with one hand. The gallery technique is also central to teapot making in the [studio pottery](https://en.wikipedia.org/wiki/Studio_pottery) tradition, where a well-fitted lid elevates a functional pot into something truly refined.

## Check your understanding

### Question 1: What measurement do you take from a gallery to throw the matching lid?

- [ ] A. The outer diameter of the pot rim
- [x] B. The inner diameter of the gallery
- [ ] C. The height of the rim above the gallery
- [ ] D. The depth of the gallery shelf

Tip: Measure the inner diameter of the gallery: that is the opening the lid must fit into.

### Question 2: When is the gallery formed during the throwing process?

- [ ] A. At the leather-hard stage before trimming
- [x] B. Immediately after throwing the walls, still on the wheel
- [ ] C. After the pot is trimmed
- [ ] D. After bisque firing

Tip: The gallery is formed immediately after throwing the walls, while the pot is still on the wheel and the clay is still soft.

### Question 3: Your gallery lid fits perfectly at leather hard, but after bisque the lid rocks slightly on the gallery. What is the best fix?

- [ ] A. Abandon the lid; there is no fix after bisque
- [x] B. Carefully sand or trim the underside of the lid contact area to remove the high spot
- [ ] C. Apply a thick glaze layer to glue the lid in place
- [ ] D. Add soft clay between gallery and lid and refire as bisque

Tip: Minor rocking at bisque can often be corrected by carefully sanding or trimming the underside of the lid's contact area so it seats on three solid points instead of a high spot.
