    How to use polymer clay Cernit ?

    Once unpacked, the clay has to be kneaded in the palm of the hand before starting modelling so that it goes 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 to get in the clay.

    There are as many uses as one could imagine ! Cernit can be moulded, sculpted, with or without tools, printed or mixed with stones, beads, feathers, powders, paints....

    How to bake polymer clay Cernit ?

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

    Be careful, 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 gently the clay with a fine-grain sandpaper. Finish with a polisher to get a maximum glossy effect. After some time, if it rubs clothing the clay could loose some of the glossy. Then, it has to be polished again. The result will be the same as with varnish. However, 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.

The polymer clay Cernit was born in the sixties, in Prague, in Czech Republic. A couple of scientifics creates this clay that will be named according to the first name of the lady which was called Cerna.

Forced to emigrate in Germany in 1963, they both decide to publish a newspaper ad to find

an investor who would help them develop the product.

Soon, Mr Manfred Guder notice the ad and decides to collaborate with the inventors. When they decide to retire, Mr Guder hire a chemist in charge of the development of the clay colour range. At that time, production takes place in the Frankfurt factory in Germany.

Over the years, the sales are running out and Cernit is only sold to 2 clients who represent together 50% of the turnover.

From 2000, Mr Guder collaborate with the company Bodson-Nélis, manufacturer of the Darwi air-drying clay. He will be distributing the clays Darwi Classic, Darwi Roc, Darwi Extra-light, to the Cernit brand.

Only 7 years later, Cernit is offered for sale, having as potential buyers Fimo, Sculpey and the belgian company, who had turned into “Darwi”. The next year, Cernit becomes officially belgian when it is taken over by Darwi.

Ever since, the Cernit range has been extended with various accessories for modelling, creating jewellery, dolls, flowers, etc. New colours and new developments are still coming... Do not miss them!
