Wire wrapping is one of the oldest techniques for making handmade jewelry. This technique is done with jewelry wire and findings similar to wire (for example, head-pins) to make components. Wire components are then connected to one another using mechanical techniques with no soldering or heating of the wire. Frequently, in this approach, a wire is bent into a loop or other decorative shape and then the wire is wrapped around itself to finish the wire component. This makes the loop or decorative shape permanent. The technique of wrapping wire around itself gives this craft its name of wire wrapping.
Examples of wire and beaded jewelry made using wire wrapping techniques date back to thousands of years BC. The British Museum has samples of jewelry from the Sumerian Dynasty, found in the cemetery of Ur that contain spiraled wire components. This jewelry is dated at approximately 2000 BC. Other samples of jewelry from Ancient Rome show wire wrapped loops (one of the important techniques in making wire wrapped jewelry). This Roman jewelry is dated to approximately 2000 years ago. In the manufacture of this early jewelry the techniques for soldering did not exist. Later, as the technique for soldering developed, the wire wrapping approach continued because it was an economical and quick way to make jewelry components out of wire.
Wire wrapping techniques are not frequently used for mass-produced jewelry because machines can cast (mold) jewelry components faster, more cheaply, and more precisely. The wire wrapping approach to making jewelry is primarily employed by individuals.
Wire wrapped jewelry is jewelry made of wire with mechanical connections instead of soldered connections. The key differences between making jewelry by wire wrapping and other approaches to making jewelry are two-fold;
A key element in wire wrapped jewelry is a loop made in wire. Loops are connected to one another to make the mechanical connections between components. A “P” loop is made by bending the wire until it touches the wire again (but this is too crude looking for serious jewelry use). The best-looking loop is the eye loop, with a full circle of wire centered over the stem of wire (like a lollipop).
P loops and eye loops are “open” loops. This means that the loop can be opened mechanically to allow it to connect to another component, which allows it to open too easily when strained. A stronger (and better looking) loop is the closed loop, where the end of the wire is wrapped around the stem of the loop three or four times, so that the loop is permanent and can't be opened, this is called a "wrapped loop". A connection between two wrapped loops must be performed BEFORE the second loop is wrapped closed.
In the simplest example of handmade wire wrapped jewelry, a bead is threaded onto a jewelry making finding called a head–pin. The bead is held in place by the “head” on the head pin. The portion of the head pin coming out of the opposite side of the bead is essentially wire. This wire is bent into a loop using hand tools and the excess wire is cut off. The resulting bead hanging from a loop is called a “bead dangle”. To complete a simple earring, the loop in the bead dangle is connected to the loop at the end of an ear wire finding leaving a completed earring.
Four tools are essential and several other tools are useful in the construction of wire wrapped jewelry. The basic tools are a flush cutter, round nose pliers, flat nose pliers and chain nose or bent chain nose pliers. A flush cutter is a special type of cutter that leaves one end of the cut wire flush or flat, while the opposite end of the cut wire is sharp or pointed. Round nose pliers are pliers with conical jaws and are used for making loops in wire. Chain nose or bent chain nose pliers have flat smooth jaws and are used for gripping and holding wire and for bending wire. Flat nose pliers are just what the name implies...they are flat on both inside surfaces and are used to keep areas flat or to make 90-degree bends in your wire.
Other useful tools used in making wire wrapped jewelry are nylon jaw pliers, a ruler, step jaw pliers, a pin vise to twist the wire, a chasing hammer, an anvil or bench block, a cup bur, loop closing or bent closing pliers and a jewelry making jig.
Wire is available is shapes such as round, square, half-round and patterns, such as flat and pre-twisted. It is also available in a variety of materials. Copper and brass wire are easy to shape and manipulate. Copper wire can be hammered quite thin. Brass wire is a little stiffer than copper, but it can be manipulated very easily. Sterling silver is soft enough to manipulate, but holds its shape well once it has been formed. Gold-filled wire is made by fusing a layer of 12-or 14-karat gold to a supporting material. Silver-filled wire is made in the same manner. The bond between the two materials is permanent.
Wire is measured by diameter, which is indicated by gauge numbers. The lower the gauge, the thicker the wire. A 12 or 14-gauge wire is fairly heavy, but ideal for making bangles and chokers. 10-gauge wire is very thick and stiff, while 26-gauge wire is very fine, almost as thin as hair. This thin wire is well-suited for coiling embellishments. 16-gauge wire is good for making jump rings and links for necklaces and bracelets, and 18-gauge wire is good to use for adding embellishments and making finer links.
Precious Metal Wire also comes in three hardnesses:
A craftsperson can purchase pre-made components instead of making them. Pre-made components come under the generic name findings. The most important findings used in making jewelry are ear wires, clasps, head pins, and jump rings.
A wire is a single usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. The term 'wire' is also used more loosely to refer to a bundle of such strands, as in "multistranded wire", which is more correctly termed a wire rope in mechanics, or a cable in electricity.
Wire wrap is an electronic component assembly technique that was invented to wire telephone crossbar switches, and later adapted to construct electronic circuit boards. Electronic components mounted on an insulating board are interconnected by lengths of insulated wire run between their terminals, with the connections made by wrapping several turns of uninsulated sections of the wire around a component lead or a socket pin.
A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.
Point-to-point construction is a non-automated method of construction of electronics circuits widely used before the use of printed circuit boards (PCBs) and automated assembly gradually became widespread following their introduction in the 1950s. Circuits using thermionic valves were relatively large, relatively simple, and used large sockets, all of which made the PCB less obviously advantageous than with later complex semiconductor circuits. Point-to-point construction is still widespread in power electronics where components are bulky and serviceability is a consideration, and to construct prototype equipment with few or heavy electronic components. A common practice, especially in older point-to-point construction, is to use the leads of components such as resistors and capacitors to bridge as much of the distance between connections as possible, often removing the need to add additional wire between the components.
An electrical connector is an electromechanical device used to join electrical conductors and create an electrical circuit. Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket. The connection may be removable, require a tool for assembly and removal, or serve as a permanent electrical joint between two points. An adapter can be used to join dissimilar connectors.
Surface-mount technology (SMT) is a method in which the electrical components are mounted directly onto the surface of a printed circuit board (PCB). An electrical component mounted in this manner is referred to as a surface-mount device (SMD). In industry, this approach has largely replaced the through-hole technology construction method of fitting components, in large part because SMT allows for increased manufacturing automation which reduces cost and improves quality - It also allows for more components to fit on a given area of substrate. Both technologies can be used on the same board, with the through-hole technology often used for components not suitable for surface mounting such as large transformers and heat-sinked power semiconductors.
An earring is a piece of jewelry attached to the ear via a piercing in the earlobe or another external part of the ear. Earrings are worn by both sexes and have been used by different civilizations in different times.
Stripboard is the generic name for a widely used type of electronics prototyping board characterized by a 0.1 inches (2.54 mm) regular (rectangular) grid of holes, with wide parallel strips of copper cladding running in one direction all the way across one side of the board. It is commonly also known by the name of the original product Veroboard, which is a trademark, in the UK, of British company Vero Technologies Ltd and Canadian company Pixel Print Ltd. In using the board, breaks are made in the tracks, usually around holes, to divide the strips into multiple electrical nodes. With care, it is possible to break between holes to allow for components that have two pin rows only one position apart such as twin row headers for IDCs.
Pliers are a hand tool used to hold objects firmly, possibly developed from tongs used to handle hot metal in Bronze Age Europe. They are also useful for bending and compressing a wide range of materials. Generally, pliers consist of a pair of metal first-class levers joined at a fulcrum positioned closer to one end of the levers, creating short jaws on one side of the fulcrum, and longer handles on the other side. This arrangement creates a mechanical advantage, allowing the force of the hand's grip to be amplified and focused on an object with precision. The jaws can also be used to manipulate objects too small or unwieldy to be manipulated with the fingers.
Safety wire or locking-wire is a type of positive locking device that prevents fasteners from falling out due to vibration and other forces. The presence of safety wiring may also serve to indicate that the fasteners have been properly tightened.
Lineman's pliers, Kleins, linesman pliers and combination pliers, or simply pliers are a type of pliers used by linemen, electrical contractors and other tradesmen primarily for gripping, twisting, bending and cutting wire, cable and small metalwork components. They owe their effectiveness to their plier design, which multiplies force through leverage.
Perfboard is a material for prototyping electronic circuits. It is a thin, rigid sheet with holes pre-drilled at standard intervals across a grid, usually a square grid of 0.1 inches (2.54 mm) spacing. These holes are ringed by round or square copper pads, though bare boards are also available. Inexpensive perfboard may have pads on only one side of the board, while better quality perfboard can have pads on both sides. Since each pad is electrically isolated, the builder makes all connections with either wire wrap or miniature point to point wiring techniques. Discrete components are soldered to the prototype board such as resistors, capacitors, and integrated circuits. The substrate is typically made of paper laminated with phenolic resin or a fiberglass-reinforced epoxy laminate (FR-4).
Jewelry wire is wire, usually copper, brass, nickel, aluminium, silver, or gold, used in jewelry making.
Wire sculpture is the creation of sculpture or jewelry out of wire. The use of metal wire in jewelry dates back to the 2nd Dynasty in Egypt and to the Bronze and Iron Ages in Europe. In the 20th century, the works of Alexander Calder, Ruth Asawa, and other modern practitioners developed the medium of wire sculpture as an art form.
Stonesetting is the art of securely setting or attaching gemstones into jewelry.
Soldering is a process in which two or more items are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Unlike welding, soldering does not involve melting the work pieces. In brazing, the work piece metal also does not melt, but the filler metal is one that melts at a higher temperature than in soldering. In the past, nearly all solders contained lead, but environmental and health concerns have increasingly dictated use of lead-free alloys for electronics and plumbing purposes.
An electrical crimp is a type of solderless electrical connection.
Round nose pliers, often called rosary pliers in the jewelry trade, are a specialized type of pliers characterized by their jaws of approximately round cross-section, usually of smooth surface finish and diameter tapering toward the tips.
Yemenite silversmithing refers to the work of Jewish silversmiths from Yemen. They were highly acclaimed craftsmen who dominated craft production in precious metals in the southern Arabian peninsula from the 18th through the mid-20th century, a period and region during which Muslims did not engage in this work. These Yemenite silversmiths were noted for their use of fine granulation and filigree, producing such ornaments as women's bracelets, necklaces, finials, etc.
In telecommunications, a line splice is a method of connecting electrical cables or optical fibers.
