wax crayons for ceramics only.

CERALINE Wax Crayons are made with a base of hydrocarbons, pigments and vitrificators. They can be used for decoration upon any ceramic foundation. Draw with CERALINE Wax Crayons, fill in with pigments, glazes or engobe, or cover it all with glaze. And discover how you too can obtain unique results in a safe and time saving way with CERALINE Wax Crayons

Colours and versions

CERALINE Wax Crayons exit in 10 basic colours and 4 oxides (FeO, CoO, CuO and MnO). All colours are available in 2 versions: SK 02a for earthenware and SK 7 for stoneware.

On demand and for a minimum volume the wax crayons are available in version SK 05a.

The version for low temperature can also be used at high temperature, but the installed line will fade out slightly. The version for high temperature cannot be used at low temperature, because the colours will fail to stick.

Indelible real colours

With CERALINE Wax Crayons you can draw upon any ceramic foundation, which is slightly rough. The installed lines are indelible. That is why it is possible to glaze with a brush without rubbing out the CERALINE lines. You can also apply a covering glaze over the CERALINE lines without masking it. The colours are stable, even after firing in reducing atmosphere.

Colouring surfaces and anti-flux

CERALINE Wax Crayons are not meant to colour surfaces. But because of the water-repellent quality of the wax, filling in the drawing with pigment or glaze will be faster and more accurate. Because of the anti-flux character of CERALINE there will be no overflow of the adjoining glaze while firing, similar to the ancient Cuerda Seca technique.


Our products are dust-free and contain no soluble salts. All applied pigments are silicon bounded (ceramic stains), with the exception of the oxide wax crayons. Contrary to common chalk crayons using CERALINE Wax Crayons will not release particles of dust, which will be a benefit to your health.

CERALINE bvba is the manufacturer of the patented wax crayons “CERALINE for ceramics only”.

Since 2004 these crayons are available at the specialist shops for ceramic requirements in different countries.

CERALINE Wax Crayons are designed by the Belgian ceramist Lucien Tinck. He first developed the wax crayons to decorate his own work in a style similar to the ancient Cuerda Seca technique.

After using these wax crayons for 15 years and improving their composition, the CERALINE Wax Crayons are now available for everyone to use. You can decorate all your ceramics with these in a simple and practical way, that brings you a lot of fun and makes you gain time.


On what surfaces CERALINE Wax Crayons can be used?

CERALINE Wax Crayons are to be used on fired clay, however the surface of the clay cannot be too smooth as the wax will not stick, just like common wax crayons on paper. Smooth clay first can be made rough with sandpaper.

Firing under reducing atmosphere.

All colours and oxides can be fired as well under oxidizing as under reducing atmosphere. Especially iron and copper oxide are more suitable for reduction firings and will give surprising results.

Colouring surfaces with CERALINE wax Crayons?

CERALINE Wax Crayons are not suitable for colouring surfaces. CERALINE is not a glaze in the shape of a crayon, it is a pigment liner. It is possible to shade with CERALINE, as long as there is enough space between the shading to allow the glaze to stick. If after glazing tick drops are formed upon the applied CERALINE lines, you can best spread them by using a soft brush.

Working temperature

CERALINE Wax Crayons should be stored and used below 30 °C, although it is possible to draw on fired clay, which is slightly warm (for instance with a hair-dryer). This will give you a fuller line and the opportunity to create more effects.

SK 02a or SK 7

SK 02a are designed for earthenware temperatures firing from 1050 °C to 1150 °C and SK 7 is for stoneware at temperatures firing from 1150 °C to 1300 °C.

CERALINE Wax Crayons for low temperature can be used at high temperature. The lines will fade out slightly in the adjoining glazes. CERALINE Wax Crayons for high temperature cannot be used for firing at low temperature. The pigments will not stick.

Glaze over CERALINE lines

You can make a drawing with CERALINE and fire it without glaze. To get the CERALINE lines well attached it is necessary to fire a little bit longer and at higher temperature as recommended.

CERALINE drawing with glaze

You can make an ornamental drawing by CERALINE lines. If you fill in the surfaces with underglaze, then you always need to apply a transparent glaze over the entire object. This will help to fix the CERALINE line optimally. You can also apply a covering glaze over the CERALINE lines by brush. The CERALINE lines will not be rubbed out and the glaze will not cover the lines while firing. The colours of the CERALINE lines stay unchanged.

CERALINE and working with sinter engobe

If you work with dark clay or smooth surfaced bisque ware, then we recommend first to spray a sinter engobe over the object. The CERALINE colours will stay nicer and fresher.
