Oiling
Oiling may refer to; * Oiling (leather processing) * Applying a drying oil finish to wooden items * Lubrication Lubrication is the process or technique of using a lubricant to reduce friction and wear and tear in a contact between two surfaces. The study of lubrication is a discipline in the field of tribology. Lubrication mechanisms such as fluid-lubric ...

Oiling (leather Processing)
Oiling is a process whereby leather is hand coated (usually by brush or tampon) with either a raw (un-emulsified) oil or a combination of raw oil, blended with emulsified oils and a penetrating aid. Hand oils can include fragrant oils that help with the smell associated with the leather, e.g., Pine Oil. Hand oils commonly consist of sulfated vegetable oils, e.g. sulfated castor oil. Oiling provides the leather with lubrication and allows it to flex repeatedly without cracking. Leather fibres that are dry and un-lubricated break very easily. Oiling does impart colour and an element of water resistance. Oiling would normally be performed on full grain aniline leathers. The most common type of leather oiled is vegetable tanned leather. See also * Currying * Russia leather Russia leather is a particular form of bark-tanned cow leather. It is distinguished from other types of leather by a processing step that takes place after tanning, where birch oil is worked into the rear face of ...

Drying Oil
A drying oil is an oil that hardens to a tough, solid film after a period of exposure to air, at room temperature. The oil hardens through a chemical reaction in which the components crosslink (and hence, polymerize) by the action of oxygen (not through the evaporation of water or other solvents). Drying oils are a key component of oil paint and some varnishes. Some commonly used drying oils include linseed oil, tung oil, poppy seed oil, perilla oil, and walnut oil. Their use has declined over the past several decades, as they have been replaced by alkyd resins and other binders. Since oxidation is the key to curing in these oils, those that are susceptible to chemical drying are often unsuitable for cooking, and are also highly susceptible to becoming rancid through autoxidation, the process by which fatty foods develop off-flavors. Rags, cloth, and paper saturated with drying oils may spontaneously combust (ignite) after a few hours as heat is released during the oxidation ...
