Tips for Slab-Building MethodUpdated 20 hours ago

Clay Consistency

Air-dry clay tends to dry out faster than other types, so always keep unused clay covered in plastic wrap or in an airtight container to prevent it from becoming too dry. If the clay starts drying out while you're working, mist it lightly with water to rehydrate it.

Drying Times

Drying time: Air-dry clay takes longer to dry depending on the thickness of your project. Typically, it will take 24-48 hours for a piece to dry completely at room temperature, but thicker pieces might need additional time. Make sure to allow your slab to dry completely before assembling to avoid cracking.

Slow Drying: To prevent cracking during drying, avoid placing the clay in a direct heat source (like a heater or oven) or in direct sunlight. Instead, dry your pieces at room temperature in a dry and well-ventilated area.

Work in Stages

Since air-dry clay can be sensitive to rapid changes in humidity, it’s best to work in stages. Complete a part of your project (e.g., the base or the body), allow it to dry slightly to a leather-hard stage, and then proceed to the next stage. This ensures more manageable handling and minimizes the risk of distortion.

Smoothing Surfaces

Air-dry clay can develop a slightly rough texture as it dries. You can smooth the surfaces by gently sanding them once dry. Use fine-grit sandpaper or a soft sponge for the best results.

Avoid Overworking

Unlike fired clay, air-dry clay can't be re-wet and worked with as easily after it begins to dry. Try to avoid overworking the clay once you've started shaping or sculpting, as this can lead to cracks or weaker bonds.
