Clay Sio2

Sio-2 is a natural modelling clay made from minerals and clays. It feels smooth and pliable in the hands, holds detail well, and is easy to shape whether you’re making something small or a larger piece. It hardens in the open air, so there’s no kiln, oven, or firing schedule to plan around.

Once dry, the clay becomes solid and durable. You can then sand, carve, or drill it, and paint or varnish it to add colour, detail, or a glossy finish.

Working tips

1. Knead the clay in your hands for a moment to warm it and make it pliable.
2. To join two pieces, dampen both surfaces slightly and press them together.
3. Let your finished piece dry in the open air, away from direct heat and strong sun. Larger or thicker pieces need more time.
4. Once dry, sand, carve, drill, paint, or varnish as you like.
5. Wrap unused clay tightly in cling film or an airtight bag so it stays soft between sessions.

Good to know

• Air-drying clay is not food-safe and isn’t meant for items that will hold food or drink.
• Pieces for outdoor use should be sealed with varnish.
• Check the pack for age guidance before using it with young children.
