The manufacturing process in each of the preparation, mixing, grinding, adjustment and filling stages is monitored by reference to optimum quality standards. Throughout the production process, Holbein chemists ensure its quality standards by test inspection of pigment purity, color tone, applicability and adhesion, physical stability, light stability, thermo stability and anti-bacterial stability. The result is a World-Class artist quality oil color without equal.
The successful Oil colorist knows that of all the colors used, the quality of white is critical. Ground 4 to 5 times, the Holbein superiority will be obvious to the user. There are six painting whites and one under painting/foundation white, all of which are high percentage pigment colors, namely: Titanium White. Permanent White SF (Super Fine), Zinc White, Silver (Flake/Lead) white, Ceramic White and Quick Drying White (an under painting white), all in poppy oil. Economically priced Permanent White EX (Extra Fine) in Safflower Oil.
Titanium White **** The most popular white, Titanium White is inert and non-reactive under most ordinary conditions. It has greater opacity than lead or zinc but tends to yellow in the short term. It is slower drying than lead but faster than zinc. It handles and mixes well, and its surface qualities may be strengthened by mixture with zinc oxide which also helps reduce the sometimes too intense tinting power inherent in titanium pigment.
Ceramic White **** A painting white developed by a joint research project of the Holbein Works Ltd. Laboratory and Japanese Government Industrial Laboratory, Ceramic White was developed to combine the most positive qualities of other painting whites when taken collectively. It contains titanium and strontium pigment which will not react with sulphur. Ceramic White offers superior surface strength without brittleness, increases tinting and covering power over lead and zinc, but when compared to titanium white, it offers increased transparency, drying time and visual whiteness. Excellent handling qualities.
Silver White *** S (Flake/Lead White) One of the first artificially produced pigments, white lead mixes well with oil to a smooth uniform viscosity and has excellent opacity and brush handling qualities. Possessing great surface strength, it is nevertheless toxic in nature and will react by darkening when exposed to sulphur compounds or fumes. The latter reactivity is not too important as lead pigment in use is normally well protected by the oils and varnishes with which it is mixed.
Permanent White **** A titanium white with the same general handling qualities but with a barium sulphate additive which inhibits yellowing in early drying while reducing tinting power and increases transparency. Available in two variations: Permanent White SF is produced using poppy oil, while Permanent White EX is produced using safflower oil.
Quick Drying White **** Made of titanium white, calcium carbonate, poppy oil, alkyd resin and petroleum solvent. This quick-drying white is best suited as an undercoat offering exceptional qualities of surface adhesion and durability. Non-yellowing and non-cracking, this white, when coated thinly (0.15mm) will dry in 4 to 5 hours, while application by brush, knife, squeegee or spatula in 2mm to 3mm textured thickness will take approximately 24 hours. Dilute and clean petroleum solvent.
**** Absolutely Permanent
S – Leaden Chemical origin colors, should avoid admixture with sulfide origin colors.
Many artists overlook or are unaware of the advantages of underpainting. Underpainting with a proper foundation not only provides a barrier between oil painting and primed surface, but will greatly enhance the full and lasting qualities of color. Use of the Holbein Foundation Colors will improve adhesive qualities of color applied on top and deepen the color tone. Quick-drying (24-30 hours), Holbein Foundation Colors may be used to build a foundation through application of rough but thin layers and may be used to prepare excellent impasto surfaces. Thick applications should be avoided as it may lessen the adhesion qualities of the finished painting. For best application results, it’s recommended to mix foundation colors with turpentine, using a palette knife, to achieve a consistency similar to mayonnaise. This will result in a level application and improved drying time. Foundation colors are available in White, Greenish, Grey, and Umber 110ml tubes.
Eleven intense colors offering excellent transparent characteristics. Holbein Transparent Colors have been designed for glazing in thin layers, permitting colors below to be visible and increased luminosity of your painting. Allow each color layer of glaze to completely dry before applying additional layers.
Colors available: Transparent Rose, Transparent Red, Transparent Vermilion, Transparent Lemon, Transparent Yellow, Transparent Green, Transparent Blue, Transparent Garnet, Transparent Violet, Transparent Brown and Transparent Black.
