Model and sculpt easily with Gédéo concrete-gray self-hardening clay, ideal for solid creations with a mineral finish.
This self-hardening clay is a natural, ready-to-use clay that hardens in the air without firing. Highly malleable, it offers excellent plasticity for shaping precise shapes and fine details. Thanks to the presence of natural cellulose fibers, it dries without cracking, even on voluminous pieces, and becomes particularly resistant once hardened. Its concrete-gray hue gives it a raw, contemporary look, perfect for decorative objects with a modern, mineral feel. Easy to clean with water, it can be worked by hand or on a potter's wheel. Once completely dry (4 to 5 days), it can be sanded, polished, drilled, painted or varnished, depending on the desired effect.
What can I do with self-hardening clay?
For your DIY projects, this clay is perfect for creating decorative or artistic pieces.

You can also create Beads caps, photophores, wall ornaments or mini sculptures with a sleek, designer look. For waterproof, non-food items, you can apply Gédéo waterproofing afterwards.
