There is a lot of confusion between foam clay, air dry clay. But essentially, foam clay is a type of air dry clay. It’s confusing because all of these different types of clays fit under the “air dry clay” category. Below is the comparison between three of the most popular types of air dry clay. For a more detailed comparison, see my blog post where I do a comprehensive comparison between the two materials.

Always store unused foam clay in an airtight container or resealable plastic bag to prevent it from drying out. Ensure there's minimal air inside the container to maintain its pliability. Covering the clay with a damp cloth before sealing can help keep it moist.

Utilize tools such as toothpicks for adding fine details, sculpting knives for shaping and cutting, and small paintbrushes for smoothing and blending. Keeping a bowl of water and a damp cloth nearby can assist with blending and smoothing the clay as you work.

Before using foam clay, stretch and knead it thoroughly to remove air pockets and make it more pliable. Be cautious not to overwork the clay, as this can weaken its structure and increase the likelihood of cracks. Ensuring an even thickness throughout your project also helps minimize cracking.

When making rolls with foam clay, use your palms instead of your fingers to achieve a more even thickness. Rolling with your fingers can lead to uneven shapes and textures. Ensure you're rolling on a clean, smooth surface to prevent any imperfections in your clay.

If your foam clay starts to dry out, add a few drops of water to rehydrate it. Knead the water into the clay thoroughly to restore its moldability. Using a damp sponge or brush while working can help keep the clay moist and easy to shape.
