Polymer clay vs air-dry clay: Which one is better?

If you’ve ever fallen down a crafty rabbit hole on TikTok or Pinterest, you’ve likely come across both polymer clay and air-dry clay. But what’s the actual difference between the two? More importantly, which one should you use for your next at-home project?

Whether you're moulding a pair of earrings, sculpting mini plant pots, or crafting with kids on a rainy day, understanding polymer clay vs air-dry clay is the first step to choosing the right medium. Let’s break it all down.

What is air-dry clay?

Air-dry clay is exactly what it sounds like—a soft, pliable clay that hardens when exposed to air. No oven, kiln, or fancy equipment needed.

Key benefits:

• No baking required: Just sculpt, set aside, and let it dry.

• Perfect for beginners and kids: Easy to handle and less messy.

• Ideal for home crafts: From trinket dishes to fridge magnets.

If you’re looking for an easy, creative afternoon project, our air-dry clay kits are a great place to start. They come with everything you need—tools, paint, and of course, clay.

What is polymer clay?

Polymer clay is a synthetic, oven-bake clay that stays soft until it’s cured in a home oven. Think jewellery, buttons, charms—anything you want to be lightweight and ultra-durable.

Key benefits:

• More durable: Once baked, it’s waterproof and chip-resistant.

• Bright, vibrant colours: Often doesn’t need painting after.

• Better for intricate details: Great for miniatures and fine work.

Our polymer clay kits are made with beginners in mind. It includes a curated selection of colours, tools for shaping, and an easy-to-follow guide.

How to paint your air-dry clay creations at home

Whether you're painting a ring dish or a name sign, here’s how to get that pro finish:

1. Wait until it’s bone dry: Rushing this will lead to cracks.

2. Sand lightly (optional): For a smooth surface, use fine sandpaper.

3. Prime if needed: Optional, but it helps paint stick better.

4. Paint: Use acrylics for bold, vibrant colour.

5. Seal: Use a waterproof sealer if it’ll be handled often.

Everything you need for this process is included in our DIY at-home clay kit. No guesswork required.

So… which one should you choose?

• Choose air-dry clay if you’re crafting with kids, short on time, or want something easy and fuss-free.

• Choose polymer clay if you want more durability, detail, or are making functional items, such as jewelry.

Honestly? There’s a reason to love both, and no rule against using both depending on the project.
