Easy to soften, this polymer clay hardens when baked. Once the creation has been modelled, simply put it in a domestic oven for 30 minutes at 130°C (no odours when baking). The object becomes solid and durable over time without any cracks. Cernit clay paste does not lose its colour. All the colours can be mixed together. As an added bonus, even after baking, its flexibility means that you can make solid, curved creations like bracelets without any risk of a breakage.
