This line of oil colours have been "re-developed" to offer the modern painter the tonalities of the Master Artists of the Italian Renaissance - in paint composition, in pigment size and the use of rare semi-drying oils that are non-yellowing and crystal clear.
These are coarsely ground oil colours not finely ground as modern oil colours, so the application (either with a brush or palette knife) and end result, are different due to the larger size of the pigment particles. Each colour has a high pigment concentration and is prepared with grain size and dispersion in walnut oil similar to those of Renaissance compositions. Most of the pigments in this range correspond to the originals; however the more toxic, unstable and hard to mix pigments have been replaced with modern alternatives. These colours can be thinned solely with Walnut oil or Safflower oil but it is best to avoid thinning with the solvents typically used to dilute oil colours - e.g. White Spirit and Turpentine
