BLACK CERALINE 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 colouring oxides in a wax base which can be used to decorate ceramic surfaces.
These crayons can be applied to bisque in any number of imaginative ways from simple line drawings to applications of wide areas of colour. They impart vibrant colours, which are permanent and will not "dust" or rub off during applications.
Each crayon is 14.60 cm long and can be fired from cone 05 to 01. 1050 ⁰C - 1150 °C .Ceraline crayons can be fired to higher temperatures, but colours may vary.
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.
SK 02a or SK 7
- SK 02a are designed for earthenware temperatures firing from 1050 °C to 1150 °C
- SK 7 is for stoneware at temperatures firing from 1150 °C to 1300 °C.
CERALINE lines cannot be covered by glaze. While glazing and firing the lines form a barrier between the surfaces to be glazed. The result is a mat coloured line between glazed surfaces, comparable to the ancient Cuerda Seca technique.
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.
