Proven Lightfastness: The pigments used are exclusi- vely chosen artist’s quality pigments, which have the highest colour strength, purity, and especially proven permanency. This pigment selection and the high pigment concentration, guarantees the best colour strength, brilliance and luminosity of LUKAS BERLIN.
Drying Time: The surface drying time for all shades is between 5 and 7 days. The same slow oxidation pro- cess takes place during the drying time. Therefore, heavy impasto painting may require up to one year to be completely dry, depending on the thickness of the layers and the pigment. The colour brilliance is in the wet as well as in the dry state consistently.
Consistency: LUKAS BERLIN contains a small propor- tion of beeswax, like the other LUKAS Artists’ Oil Colour ranges, which give the buttery consistency and the typical satin brilliance. Moreover, it contributes to a more resistant picture surface and facilitates easier varnishing and cleaning of the painting as confirmed by leading restorers.
Dilution Behaviour: LUKAS BERLIN has the same thinning characteristics as classic oil colours. By adding small amounts of water a considerable dilution appears. In contrary to classical oil colours LUKAS BERLIN must not be thinned with mediums including solvents (turpentine, citrus turpentine, other painting mediums), but simply with water. Clean up is easy with just soap and water.
Mixing Behaviour: LUKAS BERLIN can be mixed wi- thout a problem with all classic oil colours, but it loses the water miscibility benefit. You can also mix LUKAS BERLIN with Acrylics or Gouache colours. (Note: cracking may take place if not completely mixed; do not work impasto with Gouache colours). Mixing with airbrush colours (1:1 with water) can produce interesting results.
Which Mediums are available for LUKAS BERLIN?
LUKAS BERLIN Linseed Oil modified (art. no. 2250) is a drying retarder and makes the colour “more fat”. Therefore it is suitable for the wet-on- wet technique. It can also be used to produce your own water mixable oil colours.
Beyond that, all other LUKAS oil painting mediums in small concentrations (up to 30%) are useable and will achieve the same result as with classic LUKAS Oil Colours, without losing the water misci- bility. By adding larger amounts of mediums (over 30%), water miscibility will completely disappear. Mediums should be shaken before use, carefully mixed with the colour and if required, add water for thinning.
