By mastering basic techniques, potters can create an array of beautiful and functional pieces.

Pinch pottery, as the name suggests, involves shaping clay using your hands, and is ideal for creating simple pots and sculptural pieces.

Coil building, on the other hand, is a technique where clay coils are stacked and joined to form a variety of shapes and textures.

For those who like precision and angular shapes, slab construction offers a way to build pottery using flat slabs of clay.

Lastly, mold-assisted hand building uses molds to shape clay, making it easier to create consistent and intricate shapes.

Pinch Pottery Technique

The pinch pottery technique, one of the oldest forms of pottery making, is a testament to the timeless nature of this art.

Historical traces of pinch pottery can be found as far back as 20,000 years ago in China, marking the emergence of pottery in human civilization.

Creating a pinch pot begins with a ball of clay that is subsequently shaped by applying pressure with your fingers and thumb.

The simplicity and adaptability of the pinch pot method make it a favorite among beginners, allowing for the creation of diverse forms such as pinch pots, cups, coffee mugs, pitchers, and bowls.

The recommended clay for this technique is stoneware or earthenware with added grog due to its strength and reduced susceptibility to cracking.

Coil Building Technique

The coil building technique, often referred to as coil pottery, is a more intricate form of pottery making that involves the stacking and joining of clay coils to create larger, more complex designs.

This technique allows for a wider range of designs, including:

• Custom shapes
• Pots
• Sculptures
• Large-scale brick sculptures

In the coil building process, we start by:

1. Rolling out a clay coil and placing it on top of a base.
2. Affixing the coil to the base by bonding pinch.
3. Stacking and interconnecting additional coils to construct the pot walls.

It’s recommended to use stoneware or earthenware clay with added grog for this technique, as it provides the necessary plasticity and strength to maintain the structure’s shape.

To refine the technique, start with gentle pressure when shaping the coils, and as the coil lengthens, allow your hands to move outward while rolling.

Depending on the desired outcome, the coils can be left visible or smoothed to achieve a uniform surface.

Slab Construction Technique

Slab building is a hand building technique that uses flat clay slabs to create angular or square slab pots, plates, and other functional or decorative items.

The clay slabs are cut into the desired shape and size, then joined together using the “score and slip” method, which is one of the many slab building techniques.

In slab construction, maintaining a uniform thickness holds utmost importance.

The clay slab should not exceed three or four times the desired thickness, with the recommended thickness being between 1/4” to 3/8”.

To prevent common challenges like warping, it’s important to adequately compress the slab after rolling it out.

This can be achieved by thoroughly compressing one side of the slab with a rib or a wooden tool.

Also, maintaining the clay’s flatness by wedging it to ensure even moisture content and avoiding excessive handling and bending of the clay can aid in preventing warping.

Mold-Assisted Hand Building

Mold-assisted hand building, as the name suggests, utilizes molds to shape the clay.

This technique allows for the creation of uniform and intricate shapes, making it easier for beginners to achieve consistency in their pottery pieces.

There are different types of molds used in mold-assisted pottery hand building, such as:

• Slump/hump molds: These expose the inside surface of a pot.
• Drape molds: These are in contact with the interior side of the pot.
• Press molds: These are used to create uniform shapes, make use of excess clay scraps, and create larger and more stable pieces.

The choice of mold depends on the desired shape and form.
