Product Information

Color Line Paints & Pens are ready to use enamels for glass or ceramics in a fantastic range of intense colours. Available in handy squeeze bottles which, while ideal for dispensing paint can also be used directly as lining pens.

The firing range is from 700°C to 820°C (1300°F – 1510°F). All colours have extremely strong pigmentation, are lead-free and freely mixable to obtain further shades.
They are homogenous and smooth in a water friendly medium, environmentally friendly, and easy to use in exactly the required amount ensuring low wastage.

All auxiliary products are also lead-free.


All Color Line paints mix extremely well together. Mixing only a few drops of one colour into another can dramatically change the mood.

For brightening colours or to give them a more translucid quality, the Color Line Paints can be mixed with Color Line Mix White or Color Line Flux (also see Lab Notes).



All of our paint bottles have been sealed to ensure long shelf life and to prevent spillage during transport.

Unscrew the cap and remove the seal (A).
Make sure that the white foam ring (
B) remains inside the cap.

Color Line Pens need to be shaken well – approx. 30 seconds – before use. This ensures that the medium and paint remain homogenous. If the paint appears too thick and you are using it directly from the bottle (i.e. as a pen), add a small amount of Color Line Paint Thinner and shake again vigorously. Water may be added to the paint you are working with. However, the residues of this should not be returned to the original bottle. It can be kept in a separate container for future use, but will have a shortened shelf life.


Now the paint is ready for use. You can apply it in any way you can imagine. Some of the typical application techniques are shown in the section “Techniques”, but you can explore many other methods to achieve different results.

For fine line application attach one of the metal tips (C) directly onto the black nozzle and screw it tight. When interrupting the work keep the bottle upside down in a bit of water to keep the nozzle from drying. After use rinse the metal tip thoroughly with water, ideally use a squeeze bottle.


Best firing results are guaranteed if the paint application is evenly and thoroughly dried. You can air dry or dry at a low temperature in your kiln, leaving the vent holes open. The thicker the coat, the longer the drying time.


Recommended firing temperatures are 700°C to 820°C (1310°F – 1500°F). Fires glossy from 740°C (1365°F) onwards. Up to 650°C (1200°F) keep the kiln ventilated to allow the medium to exhaust. This is especially important for the red colours (more info see section “Lab Notes”). When using the paint between layers, fire the individual layers first separately. Stack or combine the components for a subsequent firing.

Do not eat, drink or smoke while working with this product. Avoid contact with eyes and do not ingest. This paint is lead free. Food safe when fired. Store in cool and dry conditions.

Auxiliary Products


Add some of Color Line Mix White to any of the colours for a very strong lightening effect without changing the density of the colour. The addition of Mix White has no effect on the firing temperature.
We recommend to use Color Line Mix White instead of White 128 when
mixing with other Color Line Paints to avoid unpredictable results.


Color Line Paints are basically opaque. Add some of Color Line Flux to any colour or colour mix to add brilliance and translucence. The paint layer is very glossy with a perception of depth. The addition of Color Line Flux does not influence the shade or the firing temperature.


Get a nice RED

The red in vitreous products is known for its special character. It has always been difficult to make a consistent red glass, those who mastered it tended to keep it secret.

Color Line offers 3 brilliant reds – 125 Carmine, 011 Red and 074 Lacquer Red – which luckily are easy to use and behave much less capriciously than many other red enamels, however, there are few things to note:

  1. Outofall Color Line products,Carmine,Red and Lacquer Red are the brightest inexpressionand shade.The yare also the most difficult to get off your fingers and clothes. If you want to be on the safe side, wear old clothes and gloves when you work with these colours.

  2. Even though the pigmentation appears and infactis very strong, you need to use a good amount of paint to havea strong registration after firing, this is especially true when you airbrush the colour.

  3. All Color Line Paints are freely mixable – including the reds. However, some mixes end up as a brownish/greyish shade after firing – looking very different from the unfired product. To be sure of your colour when mixing reds, we advise you to run some tests prior to working on a larger project.

  4. We have discovered that trying to obtain a light pink when mixing red and white is tricky. Based on the problems mentioned under point 2 the red colour tends to burn out, leaving you with the white only. In our testing we found that a ratio of 1 part red and 6 parts Mix White resulted in a pleasant pink.

  5. Reds like to be fired alone, i.e. fire the other colours before and add the red in a further separate firing. This is recommended to avoid too much medium being burnt off in the presence of red. When the medium in the paints burns off, oxygen is consumed and creates a reductive atmosphere in the kiln, which can influence the red colours.

  6. Finally, (and this is the solution to many firing problems), keep the kiln vent holes open during the firing. Especially the reds do not like the slightly reductive (oxygen poor) atmosphere you tend to have in any firing. By leaving the vent holes open, or the door slightly ajar, the kiln will draw in oxygen from outside and guarantee a neutral atmosphere and a stable and brilliant red.
