Mercury gold plating is a time-honored process where a real layer of gold is carefully applied to the Metal Wall Hangings. Skilled artisans expertly handle the amalgamation of gold with mercury, ensuring precise application and stunning results. This method not only imparts a rich and lustrous appearance to the Metal Wall Hangings but also enhances its durability, allowing the gold plating to last for an extended period.

Detailed Description of Mercury Gilding
The process of Fire Gold plating is both time-consuming and intricate, requiring skilled artisans to carefully apply the gold layer using specialized tools and techniques. Despite the labor-intensive nature of the process, the end result is a stunning work of art that is sure to impress anyone who sees it.

Fire-gilding or Wash-gilding is a process by which an amalgam of gold is applied to metallic surfaces, the mercury being subsequently volatilized, 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 chamois leather 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 nitric acid. A deposit of mercury is obtained on a metallic surface using quicksilver water, a solution of mercury(II) nitrate, the nitric acid attacking the metal to which it is applied, and thus leaving a film of free metallic mercury.

The amalgam is equally spread over the prepared surface of the metal, the mercury is then sublimed by 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 brass 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 beeswax mixed with some of the following substances: red ochre, verdigris, copper scales, alum, vitriol, and borax. 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 potassium nitrate, alum, or other salts, ground together, and mixed into a paste with water or weak ammonia. The piece of metal thus covered is exposed to heat, and then quenched 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 mercury toxicity 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 neurological damage and endocrine disorders 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 nickel substrate, which is more economical and less dangerous



Fire Gold Plating In Nepal

These mandalas, concentric diagrams, have spiritual and ritual significance in both Buddhism and Hinduism. The term is of Hindu origin and appears in the Rig Veda as the name of the sections of the work, but is also used in other Indian religions, particularly Buddhism. In the Tibetan branch of Vajrayana Buddhism, mandalas have been developed into sandpainting. They are also a key part of anuttarayoga tantra meditation practices.

Hinduism and buddhism
Buddhism
Tibetan for mandala in Vajrayana Buddhism usually depicts a landscape of the "Buddha-land", or the enlightened vision of a Buddha, which inevitably represents the nature of experience and the intricacies of both the enlightened and confused mind, or "a microcosm representing various divine powers at work in the universe." Such mandalas consist of an outer circular mandala and an inner square (or sometimes circular) mandala with an ornately decorated mandala "palace" placed at the center. Any part of the inner mandala can be occupied by Buddhist glyphs and symbols, as well as by images of its associated deities, which "symbolise different stages in the process of the realisation of the truth."

Kvarne (1975: p. 164) in his extended discussion of sahaja, discusses the relationship of sadhana interiority and exteriority in relation to mandala thus:

"...external ritual and internal sadhana form an indistinguishable whole, and this unity finds its most pregnant expression in the form of the mandala, the sacred enclosure consisting of concentric squares and circles drawn on the ground and representing that adamant plane of being on which the aspirant to Buddha hood wishes to establish himself. The unfolding of the tantric ritual depends on the mandala; and where a material mandala is not employed, the adept proceeds to construct one mentally in the course of his meditation."

Mandalas are commonly used by tantric Buddhists as an aid to meditation. More specifically, a Buddhist mandala is envisaged as a "sacred space," a "Pure Buddha Realm," and also as an abode of fully realised beings or deities. While on the one hand, the mandala is regarded as a place separated and protected from the ever-changing and impure outer world of samsara, and is thus seen as a "Buddhafield" or a place of Nirvana and peace, the view of Vajrayana Buddhism sees the greatest protection from samsara being the power to see samsaric confusion as the "shadow" of purity (which then points towards it). By visualizing "pure lands," one learns to understand experience itself as pure, and as the abode of enlightenment. The protection that we need, in this view, is from our own minds, as much as from external sources of confusion. In many tantric mandalas, this aspect of separation and protection from the outer samsaric world is depicted by "the four outer circles: the purifying fire of wisdom, the vajra circle, the circle with the eight tombs, the lotus circle." The ring of vajras forms a connected fence-like arrangement running around the perimeter of the outer mandala circle.

The mandala is also "a support for the meditating person," something to be repeatedly contemplated to the point of saturation, such that the image of the mandala becomes fully internalised in even the minutest detail and can then be summoned and contemplated at will as a clear and vivid visualized image. With every mandala comes what Tucci calls "its associated liturgy...contained in texts known as tantras," instructing practitioners on how the mandala should be drawn, built and visualised, and indicating the mantras to be recited during its ritual use.

As a meditation on impermanence (a central teaching of Buddhism), after days or weeks of creating the intricate pattern of a sand mandala, the sand is brushed together and placed in a body of running water to spread the blessings of the mandala.

A mandala can also represent the entire universe, which is traditionally depicted with Mount Meru as the axis mundi in the center, surrounded by the continents. A "mandala offering" in Tibetan Buddhism is a symbolic offering of the entire universe. Every intricate detail of these mandalas is fixed in the tradition and has specific symbolic meanings, often on more than one level.

The mandala can be shown to represent in visual form the core essence of the Vajrayana teachings. In the mandala, the outer circle of fire usually symbolises wisdom. The ring of 8 charnel grounds represents the Buddhist exhortation to always be mindful of death, and the impermanence with which samsara is suffused: "such locations were utilized in order to confront and to realize the transient nature of life." Described elsewhere: "within a flaming rainbow nimbus and encircled by a black ring of dorjes, the major outer ring depicts the eight great charnel grounds, to emphasize the dangerous nature of human life." Inside these rings lie the walls of the mandala palace itself, specifically a place populated by deities and Buddhas.

One well-known type of mandala, in Japan is the mandala of the "Five Buddhas", archetypal Buddha forms embodying various aspects of enlightenment. Such Buddhas are depicted depending on the school of Buddhism, and even the specific purpose of the mandala. A common mandala of this type is that of the Five Wisdom Buddhas (a.k.a. Five Jinas), the Buddhas Vairocana, Aksobhya, Ratnasambhava, Amitabha and Amoghasiddhi. When paired with another mandala depicting the Five Wisdom Kings, this forms the Mandala of the Two Realms.



Hindisum
A yantra is a two- or three-dimensional geometric composition used in sadhanas, or meditative rituals. It is thought to be the abode of the deity. Each yantra is unique and calls the deity into the presence of the

practitioner through the elaborate symbolic geometric designs. According to one scholar, "Yantras function as revelatory symbols of cosmic truths and as instructional charts of the spiritual aspect of human experience"

Many situate yantras as central focus points for Hindu tantric practice.Yantras are not representations, but are lived, experiential, nondual realities. As Khanna describes:
Despite its cosmic meanings a yantra is a reality lived. Because of the relationship that exists in the Tantras between the outer world (the macrocosm) and man's inner world (the microcosm), every symbol in a yantra is ambivalently resonant in inner-outer synthesis, and is associated with the subtle body and aspects of human consciousness
