Product Description

Rublev Colours Sun-Thickened Walnut Oil is made by exposing filtered, cold-pressed walnut oil to sunlight in shallow tanks covered with clear glass and exposed to the atmosphere for a period of three months. No driers or other additives are used in the making of this oil. The exposure to sunlight thickens it. This walnut oil is naturally bleached to almost water white, so it can be used with palest colors and whites.

Use
Use to make oil colors and thin oil colors. This oil is excellent for making and thinning whites and pale colors. Some woodworkers prefer walnut oil as a finish for implements that come in contact with food, such as cutting boards and wooden bowls because of its safety. People who formulate wood finishes value walnut oil as an ingredient because of the edibility of both ingredients. The oil typically is combined with beeswax in a mixture of 1:2 oil to beeswax. Use turpentine, spike oil or mineral spirits as the solvent for oil painting mediums and for brush and studio clean up.

Source
Walnut oil is a pale yellow drying oil derived from freshly dried walnuts (Juglans regia) grown in California. Over 99% of walnut oil sold in the United States of America is produced in California. There are also producers in France, Australia and New Zealand. There are two types of walnut oil commercially available: cold pressed and refined. Cold pressed walnut oil is typically more expensive due to the loss of a higher percentage of the oil. Refined walnut oil is expeller pressed and saturated with solvent to extract the highest percentage of oil available in the nut meat. The solvents are subsequently eliminated by heating the mixture to around 200&#176 C (400&#176F). Both methods produce food grade oils. However, cold pressing preserves more of the nutrients and flavorÜnot important for use in paint.

History
As early as the fifth century walnut oil was recommended by Aetius for varnishing wax pictures and gilt surfaces. It is recommended for all light pigments in the treatises on painting by Leonardo da Vinci, Vasari, Borghini, Lornazzo, Armenini, Bisagno, Volpato, and others.

Health and Safety
There are no acute or known chronic health hazards associated with the anticipated use of this product (most chemicals are not fully tested for chronic toxicity). Always protect yourself against potentially unknown chronic hazards of this and other chemical products by keeping them out of your body. Do this by avoiding ingestion, excessive skin contact, and inhalation of spraying mists, sanding dusts and vapors from heating. Conforms to ASTM D-4236.

WARNING: Rags or paper towels contaminated with vegetable drying oils, particularly those containing iron oxide pigments are susceptible to spontaneous combustion. To prevent unexpected fires, used rags or paper towels contaminated with oil-based materials should be collected in a closable, air-tight container. Store water-dampened rags or paper towels in a metal container with an air-tight top. Alternately, washing contaminated rags will remove contaminating materials and eliminate risk.

Storage
For best results store in a cool, dry place tightly closed.

  1. violin varnish

    Posted by Chris on 15th Apr 2019

    This is what I use for violin varnish. Makes a high quality varnish. Because it is sun thickened it dries a little faster than raw walnut oil from the greengrocers. I will use this every time from now on.
