Cobalt Oxide Ceraline Wax Crayon
Ceraline Crayons are a new and exciting medium formulated to impart coloured surfaces to ceramics. The crayons unique feature combines ceramic stains and metallic coloring oxides in a wax base which can be used to decorate ceramic surfaces.
They can be applied to bisque in any number of imaginative ways from simple line drawings to applications of wide areas of color. They impart vibrant color, which is indelible and will not "dust" or rub off during applications.

Each crayon is 5.75" long.
Earthenware - can be fired from 1046∞C - 1101∞C. Ceraline crayons can be fired to higher temperatures, but colors will vary.
Stoneware - Fire to1270∞C
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.
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.
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.

CERALINE drawing without glaze
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.
