In archaeology , a button can be a significant artifact. In the applied arts and in craft , a button can be an example of folk art , studio craft , or even a miniature work of art. However, buttons may be sewn onto garments and similar items exclusively for purposes of ornamentation. Buttons serving as fasteners work by slipping through a fabric or thread loop or by sliding through a buttonhole. Other types of fastenings include zippers , Velcro , and magnets.

Initially, these buttons were predominantly made of brass though horn and rubber buttons with stamped or moulded designs also exist and had loop shanks.

Chasingchased workor embossing refer to a similar technique, in which the if is hammered on the front side, sinking the metal. The two techniques Brass hollow ware methods of construction often used in conjunction. These techniques are very qare and have been extensively used all over the world, as they require only the simplest tools and materials, and yet allow great diversity of expression. Toolmarks are often intentionally left visible in the result. Chasing comes from the French word, chasser meaning to drive out, or to chase around which is what the artists are doing as they metohds the forms on their metal in order to create their final design.
During the Freee porn videa millennium BC, in the Middle East, a variety of semi-mass production methods were introduced to avoid repetitive free-hand work. The alternative to pressing gold sheet into a die is to work it over a design in cameo relief.
Here the detail would be greater on the back of the final design, so some final chasing from the front was often carried out to sharpen the detail. The use of patterned punches dates back to the first half of the 2nd millennium BCif not far earlier. The simplest patterned punches were produced by loops or scrolls of wire. The lapis lazuli and other stones were inlaid in chased areas after the height of the form was completed.
The ceremonial beard, Nekhbet vulture, and Uraeus were attached constructipn. By Hellenistic times, combined punches and dies were in use. Classical pieces using repoussage and chasing include the bronze Greek armour plates from the 3rd century BC. These vessels are generally made using sheets of copper or silver. The metal plate Brass hollow ware methods of construction usually be annealed —that Brass hollow ware methods of construction, heated for some time at a temperature somewhat below its melting point—to make it Brass hollow ware methods of construction malleable as possible.
This process may have to be repeated several times, as many metals harden and become brittle as they are deformed by the hammering. The plate must conetruction be fixed on a suitable support. A commonly used technique is to place the metal over a layer of chasers pitch. At room temperature, the pitch must be hard enough to adhere to the metal and hold it in place, but still soft and plastic enough to "give" as the metal is hammered into it.
The pitch is often cast as a thick layer over some softer backing material that Pheonix bondage model absorb larger deformations. Pitch residues stuck to the plate must be Brxss with an appropriate solvent.
Once the plate is firmly held by the pitch, front side up, the outline of the desired design is lightly chased "lined" on it by a special tool a "liner"that creates narrow raised lines on the other side. The metal is turned over, and firmed again over the pitch, with the back side up.
Once that filling has hardened, the plate is again turned over and placed on top of a nollow of softened pitch. Once the pitch has hardened, the design is then refined by chasing. That is accomplished by heating the piece to a high enough temperature to make it malleable, as in forging. In this case pitch must be dispensed with, or replaced by some material like sand that can withstand the heat and provide the right kind of "giving" support.
The tools needed for these techniques are . Other tools are usually handy, such as tweezers or tongs to hold the hot plates. The punches are usually made of steel, especially tool steel —a hard alloy that can keep its shape Tg latex powdered gloves after years Brazs use—and are forged and tempered at the tip.
They usually have a beveled rear end, to better handle the hammer blows.

Brass is a metal composed primarily of copper and zinc. Copper is the main component, and brass is usually classified as a copper alloy. Brass is stronger and harder than copper, but not as strong or hard as steel. It is easy to form into various shapes, a good conductor of heat, and generally resistant to corrosion from salt water. Because of these properties, brass is used to make pipes and tubes, weather-stripping and other architectural trim pieces, screws, radiators, musical instruments, and cartridge casings for firearms. Ancient metalworkers in the area now known as Syria or eastern Turkey knew how to melt copper with tin to make a metal called bronze as early as B. Sometimes they also made brass without knowing it, because tin and zinc ore deposits are sometimes found together, and the two materials have similar colors and properties. By about 20 B.
