For the surname, see. The term gilding covers a number of decorative techniques for applying fine or powder to solid surfaces such as wood, stone, or metal to give a thin coating of.
A gilded object is also described as 'gilt'. Where metal is gilded, it was traditionally in the West, to make (or ) objects, but is commonly used in China, and also called if it is Western. Methods of gilding include hand application and glueing, chemical gilding, and, the last also called. Parcel-gilt (partial gilt) objects are only gilded over part of their surfaces. This may mean that all of the inside, and none of the outside, of a or similar vessel is gilded, or that patterns or images are made up by using a combination of gilt and un-gilt areas. A gilded Tibetan mentions that the gilded wood and metals, and many such objects have been excavated.
Certain Ancient Greek statues of great prestige were, i.e., made of gold (for the clothing) and (for the flesh); these however, were constructed with sheets of gold over a timber framework, not gilded. Extensive ornamental gilding was also used in the ceiling coffers of the. Informs us that the first gilding seen at was after the destruction of, under the censorship of, when the Romans began to gild the ceilings of their temples and palaces, the being the first place on which this process was used. But he adds that luxury advanced on them so rapidly that in very little time you might see all, even private and poor people, gild the walls, vaults, and other parts of their dwellings. Owing to the comparative thickness of the gold leaf used in ancient gilding, the traces of it that remain are remarkably brilliant and solid. Fire-gilding of metal goes back at least to the 4th century BC, and was known to Pliny (33,20,64–5), (8,8,4) and in the Early Mediaeval period to Theophilus (De Diversis Artibus Book III). In Europe, silver-gilt has always been more common than gilt-bronze, but in China the opposite has been the case.
The ancient Chinese also developed the gilding of, which was later taken up by the French and other European potters. Processes Modern gilding is applied to numerous and diverse surfaces and by various processes; those used in modern technology are described in.
More traditional techniques still form an important part of and are sometimes still employed in general, -work, decorative painting and, and ornamental work, and in the decoration of, porcelain, and. Mechanical gilding. Gilded page edges on a book. Mechanical gilding includes all the operations in which gold leaf is prepared, and the processes to mechanically attach the gold onto surfaces. The techniques include, water gilding and oil-gilding used by wood carvers and gilders; and the gilding operations of the house decorator, sign painter, the paperstainer and several others. Polished iron, steel and other metals are gilded mechanically by applying gold leaf to the metallic surface at a temperature just under red-hot, pressing the leaf on with a burnisher, then reheating when additional leaf may be laid on.
The process is completed by cold burnishing. 'Overlaying' or folding or hammering on gold foil or gold leaf is the simplest and most ancient method, and is mentioned in 's (Bk vi, 232) and the. The of about 2600–2400 BCE from uses this technique on wood, with a thin layer of underneath to help adhesion. The next advances involved two simple processes. The first involves gold leaf, which is gold that is hammered or cut into very thin sheets.
Gold leaf is often thinner than standard paper today, and when held to the light is semi-transparent. In ancient times it was typically about ten times thicker than today, and perhaps half that in the. If gilding on canvas or on wood, the surface was often first coated with. 'Gesso' is a substance made of finely ground or chalk mixed with glue. Once the coating of gesso had been applied, allowed to dry, and smoothed, it was re-wet with a made of and water ('water gilding', which allows the surface to be subsequently burnished to a mirror-like finish) or boiled mixed with ('oil gilding', which does not) and the gold leaf was layered on and left to dry. Those gilding on canvas and parchment also sometimes employed stiffly-beaten egg whites ('glair'), and/or as sizing, though egg whites and gum both become brittle over time, causing the gold leaf to crack and detach, and so honey was sometimes added to make them more flexible. Other gilding processes involved using the gold as pigment in paint: the artist ground the gold into a fine powder and mixed it with a binder.
Then the gold was applied in the same way as with any paint. Sometimes, after either gold-leafing or gold-painting, the artist would heat the piece enough to melt the gold slightly, ensuring an even coat.
These techniques remained the only alternatives for materials like wood, leather, the vellum pages of, and gilt-edged stock. Chemical gilding. Silver gilt toilette set by Johann Jacob Kirstein (1733–1816) in the Chemical gilding embraces those processes in which the gold is at some stage of chemical combination. These include: Cold gilding In this process the gold is obtained in a state of extremely fine division, and applied by mechanical means. Cold gilding on silver is performed by a solution of gold in, applied by dipping a linen rag into the solution, burning it, and rubbing the black and heavy ashes on the silver with the finger or a piece of leather or cork. Wet gilding Wet gilding is effected by means of a dilute solution of with twice its quantity of. The liquids are agitated and allowed to rest, to allow the ether to separate and float on the surface of the acid.
The whole mixture is then poured into a funnel with a small aperture, and allowed to rest for some time, when the acid is run off and the ether separated. The ether will be found to have taken up all the gold from the acid, and may be used for gilding iron or steel, for which purpose the metal is polished with fine emery and. The ether is then applied with a small brush, and as it evaporates it deposits the gold, which can now be heated and polished. For small delicate figures, a pen or a fine brush may be used for laying on the ether solution. The gold(III) chloride can also be dissolved in water in wherein the gold is slowly reduced out of solution onto the surface to be gilded.
When this technique is used on the second surface of glass and backed with silver, it is known as '. Fire-gilding Fire-gilding or Wash-gilding is a process by which an of gold is applied to metallic surfaces, the being subsequently, leaving a film of gold or an amalgam containing 13 to 16% mercury. In the preparation of the amalgam, the gold must first be reduced to thin plates or grains, which are heated red-hot, and thrown into previously heated mercury, until it begins to smoke.
When the mixture is stirred with an iron rod, the gold is totally absorbed. The proportion of mercury to gold is generally six or eight to one. When the amalgam is cold, it is squeezed through to separate the superfluous mercury; the gold, with about twice its weight of mercury, remains behind, forming a yellowish silvery mass with the consistency of butter. When the metal to be gilded is wrought or chased, it ought to be covered with mercury before the amalgam is applied, that this may be more easily spread; but when the surface of the metal is plain, the amalgam may be applied to it directly. When no such preparation is applied, the surface to be gilded is simply bitten and cleaned with. A deposit of mercury is obtained on a metallic surface by means of quicksilver water, a solution of, the nitric acid attacking the metal to which it is applied, and thus leaving a film of free metallic mercury.
The amalgam being equally spread over the prepared surface of the metal, the mercury is then by a heat just sufficient for that purpose; for, if it is too great, part of the gold may be driven off, or it may run together and leave some of the surface of the metal bare. When the mercury has evaporated, which is known by the surface having entirely become of a dull yellow color, the metal must undergo other operations, by which the fine gold color is given to it. First, the gilded surface is rubbed with a scratch brush of wire, until its surface is smooth. It is then covered with gilding wax, and again exposed to fire until the wax is burnt off.
Gilding wax is composed of mixed with some of the following substances:, copper scales, and. By this operation the color of the gilding is heightened, and the effect seems to be produced by a perfect dissipation of some mercury remaining after the former operation. The gilt surface is then covered over with, alum or other salts, ground together, and mixed into a with water or weak. The piece of metal thus covered is exposed to heat, and then in water. By this method, its color is further improved and brought nearer to that of gold, probably by removing any particles of copper that may have been on the gilt surface. This process, when skillfully carried out, produces gilding of great solidity and beauty, but owing to the exposure of the workmen to mercurial fumes, it is very unhealthy. There is also much loss of mercury to the atmosphere, which brings extremely serious environmental concerns as well.
This method of gilding metallic objects was formerly widespread, but fell into disuse as the dangers of became known. Since fire-gilding requires that the mercury be volatilized to drive off the mercury and leave the gold behind on the surface, it is extremely dangerous. Breathing the fumes generated by this process can quickly result in serious health problems, such as and, since inhalation is a very efficient route for mercuric compounds to enter the body. This process has generally been supplanted by the electroplating of gold over a, which is more economical and less dangerous. Depletion gilding. Main article: In depletion gilding, a subtractive process discovered in, articles are fabricated by various techniques from an alloy of copper and gold, named by the.
The surface is etched with acids, resulting in a surface of porous gold. The porous surface is then down, resulting in a shiny gold surface.
The results fooled the into thinking they had massive quantities of pure gold. The results startled modern, because at first the pieces resemble electroplated articles.
Gilded Edge Framing
Is a special technique of silver-gilding, using. Ceramics. Buddha, 16th Century, gilt on wood. The Walters Art Museum. The gilding of decorative has been undertaken for centuries, with the permanence and brightness of gold appealing to designers. Both porcelain and are commonly decorated with gold, and in the late 1970s it was reported that 5 tonnes of gold were used annually for the decoration of these products. Some wall also have gold decoration.
Application techniques include, banding machines, and direct or indirect. After application the decorated ware is fired in a to fuse the gold to the and hence ensure its permanence.
The most important factors affecting coating quality are the composition of applied gold, the state of the surface before application, the thickness of the layer and the firing conditions. A number of different forms and compositions are available to apply gold to ceramic, and these include:. Acid-etched gilding – developed in 1860s at, and patented in 1863.
The glazed surface, usually a narrow border, is with a waxlike resist, after which the glaze is etched with dilute prior to application of the gold, after which the design's raised elements are selectively burnished to give a bright and matte surface; the process demands great skill and is used for the decoration only of ware of the highest class. Bright Gold or Liquid Gold is a solution of gold sulphoresinate together with other metal resinates and a bismuth-based flux. It is particularly bright when drawn from the decorating kiln and so needs little further processing. This form of gilding was invented or at least improved. Rhodium compounds are used to improve the binding to the substrate. Burnish Gold or Best Gold is applied to the ware as a suspension of gold powder in essential oils mixed with lead borosilicate or a bismuth-based flux. This type of gold decoration is dull as taken from the kiln and requires burnishing, usually with agate, to bring out the colour.
As the name suggests it is considered the highest quality of gold decoration. One -free burnish gold composition was reported to consist of 10 to 40% gold powder, 2 to 20%, 3 to 30% an aqueous acrylate resin and 5 to 50% water. See also.
