A Beginner’s Guide to Using Air Dry Clay

Air dry clay is a firm favourite amongst hobbyists and art enthusiasts. Its versatility, ease of use and the fact that it doesn’t need to be fired make it a perfect choice for children, beginners and even seasonal artists. In this comprehensive guide, we explain the basics of air dry clay, how to make it dry faster, how to store it properly and more.

What Is Air Dry Clay?

Air dry clay, or air hardening clay, is a type of modelling clay that hardens and dries naturally when exposed to room-temperature air, eliminating the need for baking in an oven or firing in a kiln. This air-drying clay mainly consists of natural clay, fibres and other additives. One of the key advantages of air dry clay is it’s suitable for all ages and skill levels. It is also available in a variety of colours including grey and red.

What Can I Make with It?

There are endless creative possibilities with air dry clay. Here are some examples of where it is often used:

• Jewellery
• Figurines
• Sculptures
• Seasonal ornaments such as Christmas tree decorations
• Vases
• Plant pots
• Decorative bowls, mugs and trays

How Do I Shape It?

Shaping the clay is where your masterpiece comes to life. Begin by kneading your clay to make it soft and pliable, removing any air bubbles that might cause cracks during the drying process. Pottery tools such as rolling pins, cutters and coilers can shape and texture the clay. For fine designs, use carving tools such as clay needles to imprint patterns.

Keep your hand wet or cover the clay with a damp cloth during work sessions to prevent it from drying out. For joining parts, score the surfaces to be joined and wet them with a little water before pressing them together, ensuring a secure bond as the clay dries. Use your fingers to smoothen any imperfections.

Can You Bake Air Dry Clay?

As mentioned before, air dry clay is designed to dry naturally at room temperature, so baking or firing is unnecessary. However, the clay can be baked according to the manufacturer's instructions to speed up the drying process. Typically, it can be oven-baked at 93°C (200°F) for no longer than 20 minutes. Always check if your air dry clay is suitable for baking beforehand. Don’t place the clay in a preheated oven, allow it to heat up slowly. Going from room temperature to 93°C can increase the risk of cracking. After 20 minutes, turn off the oven and allow the clay to cool down.

How Long Does It Take to Dry?

Once your project is finished, you can leave it to dry naturally. The drying time for air dry clay depends on several factors, including the thickness of your piece, environmental conditions, and specific brand of clay. On average, air dry clay takes 24 hours to dry. For thicker pieces, it may take up to 72 hours. Ensure that your piece is fully dry before painting or sealing. To check if the clay is fully dry, gently tap the surface and it could make a solid sound.

How Can I Make It Dry Faster?

Allowing your project to dry for 24 hours or more can seem too long. If you want to speed up the drying process, there are several ways to do so:

1. Increase Air Circulation - Keep your piece in a well-ventilated room or use a fan to improve airflow.
2. Elevate the Piece - Leave your piece to dry on a wire rack. This allows air to reach all sides and underneath.
3. Use Heat - As mentioned before, an oven on a low temperature or a hair dryer on a cool setting can help shorten the drying time. If you are using heat, make sure you closely monitor your piece to avoid cracking or warping.

What's the Best Way to Store Leftover Clay?

If you have any leftover clay, it can be kept for future projects. Simply wrap it in cling film and place it in an airtight container to retain its moisture. Store the container in a cool, dark place. If the clay begins to stiffen or becomes difficult to work with, add a few drops of water and knead it until it softens.

What Can I Use to Seal It?

Sealing air dry clay is crucial for preserving and protecting your creations. Once your piece is fully dry, it can be sealed with a varnish or glaze of your choice using a brush. Apply the sealant in light, even layers. Multiple light layers are better than one thick coat. Allow the sealant to dry according to the manufacturer's instructions. Sealing not only preserves and protects your creations but also gives them a polished and appealing finish.
