Cernit Polymer Clay is modelling clay which is permanently hardened by baking in a domestic oven. Cernit polymer clay after baking gives a porcelain-like finish.


Advice for use:

Suitable for ages 8 and above with adult supervision.


Roll a piece of Cernit by hand and knead gently. This makes the material supple and shapeable in any direction. It can be drawn out finely like pastry and folded like cloth. Always work with clean hands on a clean surface. All colours can be mixed with each other, and blended, marbled or lightened with opaque white.

Structure and decoration:

You can cut shapes from Cernit, make deep impressions for moulding, sculp with nails, brushes, scissors and surface decorate with impressions from leaves, lace, feathers or other raised surfaces.


Pre-heat electric ovens at 110° to 130°C /230°F to 266°F. Do not use a microwave oven. After baking Cernit is so firm that it can be drilled, filed or sanded. Use acrylic paints or water colours and enhance with decorative powders or even varnish. Allow your creativity to run free!

Safety rules:

Safety rules in accordance with EU standard EN 71/1/3/5/9 Modelling materiel should not be put in the mouth. Do not exceed maximum 130°C / 266°F baking temperature as harmful gases could develop. Do not exceed a baking time of 30 minutes. Clean all equipment after use and assure hands are washed. Do not eat, drink or smoke in the activity area.
