Opaline Polymer Clay – Cernit


The finish of the Cernit Opaline is slightly translucent which makes them perfect for objects such as jewels, figurines, decorative objects and more. Mix Opaline and Translucent in the same ratios to vary the transparency effect. To create figurines, alternate Number One and Opaline for more realism. Thanks to the light transparency of the Cernit Opaline, your creations will have a ceramic-like, semi-translucent finish.

How to use (Cernit) polymer clay:

Once unpacked, the clay has to be kneaded in the palm before starting modelling so that it becomes softer and easier to work with. The clay should be used with clean hands on a clean surface as well to prevent any dirt or dust from getting in the clay.

How to bake (Cernit) polymer clay:

The Cernit clay polymerises between 110 and 130°C (230-266°F) in a preheated oven. Baking time is 30 minutes. The temperature should be respected as harmful gases could develop and the colour could be corrupted.

Please note that this clay cannot be baked in a microwave oven. After baking, the clay is waterproof. Also, it can be baked several times if you wish to add bits to your work.

When you are done baking, the clay can still be worked with. It can be sanded, drilled, varnished according to the finish you like. For polishing, start with sanding the clay with fine-grain sandpaper. Finish with a polisher to get a maximum glossy effect.  The clay could lose some of the glossiness. Then, it has to be polished again. The result will be the same as with varnish. However, the varnish will resist the rubbing and does not need to be applied again.

As soon as your piece of clay is baked and maybe polished, you can still work on it by adding acrylic paints, oil paints, mica powders or varnish.


Cernit does not contain any phthalates. Children should not be left without a watch while using the clay. This product must not be put in the mouth and we advise washing hands after each use.

One should not eat, drink or smoke in an area that is dedicated to modelling Cernit.

Please note: we do not stock the complete range. Currently we do not have the Porcelain, the Glamour and the Shiny range.
