French Polish
French polishing is a wood finishing technique that results in a very high gloss surface, with a deep colour and chatoyancy. French polishing consists of applying many thin coats of shellac dissolved in denatured alcohol using a rubbing pad lubricated with one of a variety of oils. The rubbing pad is made of absorbent cotton or wool cloth wadding inside of a piece of fabric (usually soft cotton cloth) and is commonly referred to as a ''fad'', also called a rubber, tampon, or (Spanish for 'rag doll'). French polish is a process, not a material. The main material is shellac, although there are several other shellac-based finishes, not all of which classify as French polishing. The French polish technique is an effective method to accent exotic wood grain. The finish is softer than modern varnishes and lacquers, and is particularly sensitive to spills of water or alcohol, which may produce white cloudy marks, as does heat damage. On the other hand, French polish is simpler to repa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacquer
Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity. Asian lacquerware, which may be called "true lacquer", are objects coated with the treated, dyed and dried sap of ''Toxicodendron vernicifluum'' or related trees, applied in several coats to a base that is usually wood. This dries to a very hard and smooth surface layer which is durable, waterproof, and attractive in feel and look. Asian lacquer is sometimes painted with pictures, inlaid with shell and other materials, or carved lacquer, carved, as well as maki-e, dusted with gold and given other further decorative treatments. In modern techniques, lacquer means a range of clear or pigmented coatings that dry by solvent evaporation to produce a hard, durable finish. The finish can be of any sheen level from ultra wikt:matte, matte to high Gloss (material appearance), glos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carnauba Wax
Carnauba (; ), also called Brazil wax and palm wax, is a wax of the leaves of the carnauba palm '' Copernicia prunifera'' (synonym: ''Copernicia cerifera''), a plant native to and grown only in the northeastern Brazilian states of Ceará, Piauí, Paraíba, Pernambuco, Rio Grande do Norte, Maranhão and Bahia. It is known as the "Queen of Waxes". In its pure state, it is usually available in the form of hard yellow-brown flakes. It is obtained by collecting and drying the leaves, beating them to loosen the wax, then refining and bleaching it. As a food additive, its E number is E903. Composition Carnauba consists mostly of aliphatic esters (40 wt%), diesters of 4-hydroxycinnamic acid (21.0 wt%), ω-hydroxycarboxylic acids (13.0 wt%), and fatty alcohols (12 wt%). The compounds are predominantly derived from acids and alcohols in the C26-C30 range. It is distinctive for its high content of diesters and its methoxycinnamic acid. It is sold in grades of T1, T3 and T4 accordi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copal
Copal is a tree resin, particularly the aromatic resins from the copal tree '' Protium copal'' ( Burseraceae) used by the cultures of pre-Columbian Mesoamerica as ceremonially burned incense and for other purposes. More generally, copal includes resinous substances in an intermediate stage of polymerization and hardening between "gummier" resins and amber. Copal that is partly mineralized is known as copaline. It is available in different forms; the hard, amber-like yellow copal is a less expensive version, while the milky-white copal is more expensive. Etymology The word "copal" is derived from the Nahuatl language word , meaning "incense". History and uses Subfossil copal is well known from New Zealand ( kauri gum from '' Agathis australis'' (Araucariaceae)), Japan, the Dominican Republic, Colombia, and Madagascar. It often has inclusions and is sometimes sold as "young amber". When it is treated or enhanced in an autoclave (as is sometimes done to industrialized Balt ...

Sandarac
Sandarac (or sandarach) is a resin obtained from the small cypress-like tree '' Tetraclinis articulata''. The tree is native to the northwest of Africa with a notable presence in the Southern Morocco part of the Atlas Mountains. The resin exudes naturally on the stems of the tree. It is also obtained by making cuts on the bark. It solidifies when exposed to the air. It comes to commerce in the form of small solid chips, translucent, and having a delicate yellow tinge. Morocco has been the main place of origin of sandarac. A similar resin is obtained in southern Australia from some species of the Australian cypress-like trees '' Callitris'', but the resin has not been systematically collected in Australia.''Analysis of Resins, Balsams and Gum-Resins'' by Karl Dieterich (1920), Chapter II, Section ...

Boiled Linseed Oil
Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colorless to yellowish oil obtained from the dried, ripened seeds of the flax plant (''Linum usitatissimum''). The oil is obtained by pressing, sometimes followed by solvent extraction. Owing to its polymer-forming properties, linseed oil is often blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum. Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins—which function similarly but resist yellowing.

Olive Oil
Olive oil is a vegetable oil obtained by pressing whole olives (the fruit of ''Olea europaea'', a traditional Tree fruit, tree crop of the Mediterranean Basin) and extracting the oil. It is commonly used in cooking for frying foods, as a condiment, or as a salad dressing. It can also be found in some cosmetics, pharmaceuticals, soaps, and fuels for traditional oil lamps. It also has additional uses in some religions. The olive is one of three core food plants in Mediterranean cuisine, with wheat and grapes. Olive trees have been cultivated around the Mediterranean since the 8th millennium BC. In 2022, Spain was the world's largest producer, manufacturing 24% of the world's total. Other large producers were Italy, Greece, and Turkey, collectively accounting for 59% of the global market. The composition of olive oil varies with the cultivar, altitude, time of harvest, and extraction process. It consists mainly of oleic acid (up to 83%), with smaller amounts of other fatty acids ...

Walnut Oil
Walnut oil is oil extracted from walnuts, ''Juglans regia''. The oil contains polyunsaturated fatty acids, monounsaturated fatty acids, and saturated fats. Composition According to gas chromatographic and HPLC analysis, virgin walnut oil consists of linoleic acid (60–62%). It also contains many phenolc compounds including γ-tocopherol, tanins, and flavanoids. Several of these exhibit antioxidant properties. According to another source, walnut oil is composed largely of polyunsaturated fatty acids (72% of total fats), particularly alpha-linolenic acid (14%) and linoleic acid (58%), oleic acid (13%), and saturated fats (9%). Walnuts typically contain high concentrations of phenolics including ellagic acid. Culinary use Walnut oil is edible and is generally used less than other oils in food preparation, often due to high pricing. It is light-coloured and delicate in flavour and scent, with a nutty quality. Although chefs sometimes use walnut oil for pan-frying, most ...

Abrasive Buffing
An abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away by friction. While finishing a material often means polishing it to gain a smooth, reflective surface, the process can also involve roughening as in satin, matte or Bead (woodworking), beaded finishes. In short, the ceramics which are used to cut, grind and polish other softer materials are known as abrasives. Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. This gives rise to a large variation in the physical and chemical composition of abrasives as well as the shape of the abrasive. Some common uses for abrasives include Grinding (abrasive cutting), grinding, polishing, buffing, honing (metalworking), honing, cutting, drilling, sharpening, lapping, and sanding (see abrasive machining).

Nitrocellulose
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. It was also used to replace gunpowder as a low-order explosive in mining and other applications. In the form of collodion, it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s. In the 20th century, it was adapted to automobile lacquer and adhesives. Production The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. The quality of the cellulose is important. Hemicellulose, lignin, pentosans, and mineral salts give inferior nitrocelluloses. In organic chemistry, nitrocellulose is a nitrate ester, not a ...

Wood Finishing
Wood finishing refers to the process of refining or protecting a wooden surface, especially in the production of furniture where typically it represents between 5 and 30% of manufacturing costs. Finishing is the final step of the manufacturing process that gives wood surfaces desirable characteristics, including enhanced appearance and increased resistance to moisture and other environmental agents. Finishing can also make wood easier to clean and keep it sanitized, sealing pores that can be breeding grounds for bacteria. Finishing can also influence other wood properties, for example tonal qualities of musical instruments and hardness of flooring. In addition, finishing provides a way of giving low-value woods the appearance of ones that are expensive and difficult to obtain. Planning the finish Finishing of wood requires careful planning to ensure that the finished piece looks attractive, performs well in service and meets safety and environmental requirements.
