# Building a Bottle in Three Stages

A bottle is really three forms stacked into one: a wide, rounded body at the bottom; a shoulder that curves inward; and a narrow neck at the top. Each stage requires different techniques.

## Stage 1: Throw the Body

Open and pull the walls to create a wide cylinder or rounded form: the body of your bottle. Leave the walls slightly thicker than usual near the top, because you will be collaring that clay inward and it needs the extra mass.

## Stage 2: Create the Shoulder

Using gentle inward pressure from the outside, begin collaring the top of the cylinder inward to form the shoulder curve. Move slowly. The shoulder should curve gracefully; abrupt angles at this stage are hard to fix later.

*   Keep the wheel spinning at a medium speed during this stage.
*   Support the outside of the shoulder with one hand while using the other to guide the curve inward.

## Stage 3: Throw the Neck

Once the shoulder is established, continue collaring to draw the opening up into a neck. At this stage, the opening is narrow enough that you must work entirely from the outside.

*   Use two or three fingers wrapped around the neck to guide the clay upward and compress it.
*   Keep the neck walls even in thickness: thin areas will wobble or collapse.
*   Finish the lip with a light pinch and smooth it cleanly.

The bottle is one of the most satisfying forms to throw. Take your time with the shoulder: that transition from wide body to narrow neck is what gives a bottle its character.

## The Bigger Picture

The bottle form has been central to ceramics for thousands of years, from ancient [earthenware](https://en.wikipedia.org/wiki/Earthenware) storage vessels to the refined [porcelain](https://en.wikipedia.org/wiki/Porcelain) bottles of the Chinese Song dynasty. The shoulder curve that defines a bottle's character is a direct result of the collaring technique, and studying historical examples is one of the best ways to develop your eye for proportion.

## Common Mistakes and Quick Fixes

*   **Thin top walls before shoulder stage**: Leave extra mass near the top at the start.
*   **Abrupt shoulder transitions**: Build shoulder curves gradually with controlled support.
*   **Neck wobble from uneven thickness**: Pause and even wall thickness before narrowing more.
*   **Overworking the lip at the end**: Finish quickly with light compression and stop.

## Practice Exercise

Throw a three-bottle series with identical body width but different neck heights and shoulder arcs. Line them up and evaluate proportion. This develops shape judgment faster than repeating one profile blindly.

## Check your understanding

### Question 1: Why should you leave the top walls slightly thicker when starting a bottle?

- [ ] A. Thick walls at the top make the bottle easier to handle after firing
- [x] B. That clay mass is needed for collaring the shoulder and neck
- [ ] C. Thick tops prevent the bottle from warping in the kiln
- [ ] D. It balances the weight of the wider base

Tip: The top walls will be collared inward to form the shoulder and neck. Extra thickness at the top provides enough clay mass to work with during those stages.

### Question 2: What gives a bottle its most distinctive visual character?

- [ ] A. The width of the base, which determines how stable it looks
- [x] B. The shoulder curve: the transition from body to neck defines the bottle's entire character
- [ ] C. The height of the neck relative to the body height
- [ ] D. The wall thickness of the body, which affects how the glaze pools

Tip: The shoulder (the curved transition from the wide body to the narrower neck) defines the whole character of a bottle. A gradual, confident shoulder curve reads as elegant and resolved. An abrupt or awkward shoulder makes the whole form feel unintentional.
