Diarylide yellow is a deep warm translucent yellow. It is offered by commercial artists paint manufacturers as a replacement for Indian Yellow, a historical pigment that was brought from India. According to 19th century authors the historical pigment was processed from cow’s urine and used in Europe in the 18th and 19th centuries for watercolor. Diarylide yellow has similar warm tones as Indian Yellow. Its lightfastness is very good, and is stable when used full strength, but is less so in tints.Composition and Permanence

Ceracolors is water-soluble wax paint that can be used for encaustic and wax painting techniques. Ceracolors makes encaustic painting versatile because heat, electricity and special tools are not required.
Ceracolors is a wax paint for professional artists made from pharmaceutical-grade beeswax blended with other waxes derived from natural sources to provide higher melting temperatures. Ceracolors provide a wide range of painting techniques from thick impastos that can be sculpted to thin watercolor-like washes. They are fast-drying colors suitable for all supports used for encaustic painting, yet they do not require any special tools and heated instruments. Use any brush suitable for water-based paint. Once dry Ceracolors can be used in encaustic technique, allowing further sculpting and manipulation of the paint. The ingredients in Ceracolors are found in food and cosmetics so they are not considered to be toxic.
The current range of Ceracolors are available in 50ml aluminum collapsible tubes and mediums are available in 4 and 8 fluid ounce jars.Properties Drying
Ceracolors dry in two stages. First, the paint dries rapidly due to the evaporation of water, so it is touch dry within a short time. After this initial period, the paint can be reopened with a wet brush. During the second stage, wax crystals coalesce as the paint cures. This can take several days or several weeks for thicker applications of paint.Water Solubility
Ceracolors are thinned with water. The paint comes out of the tube as a paste and can be diluted to the consistency of watercolors. The water solubility of Ceracolors allows easy handling and cleaning.Color and Optical Quality
Ceracolors are available in a wide range of colors that are used by artists in other professional-quality mediums. Ceracolors are formulated for high tinting strength and the optical qualities of wax provide outstanding chroma.Hardness
Ceracolors are made with a blend of waxes microemulsified in water. Wax is soft with low scratch resistance so works require care when handling and storing.Durability
Water-soluble wax paint is durable, as attested by the present state of preservation of Roman and Roman-Egyptian paintings of the first century in many museums throughout the world.Toxicity
Ceracolors are composed of ingredients that are not considered toxic—ingredients that are often found in food and cosmetics. There are no hazardous solvents or additives.Supports
Rigid supports, such as wood, are best for wax painting technique, but canvas and paper can also be used. Ceracolors can be applied onto other materials, such as ceramics, glass, metal or plastic.Use Directions Heat Setting
Uncured paint has limited wet scrub resistance, especially in thick layers. This resistance increases when the paint is fused by heat. Heat can be applied by a heat gun, hair dryer or pastry torch.Impasto
With Ceracolors you can apply thick passages of paint. However, like all paints that use water as a vehicle, you will experience some shrinkage during drying due to the evaporation of water. We recommend that thick impastos be built up by layering thinner applications of paint and then fusing each layers with heat. The addition of Ceracolors Impasto Medium helps to avoid excessive volume loss upon drying.Clean Up
Cleaning brushes and equipment is easy with soap and water. Dried Ceracolors water-soluble wax paint can be cleaned with household ammonia.
