Wire

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 comes in solid core, stranded, or braided forms. Although usually circular in cross-section, wire can be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-woundcoil springs, such as the Slinky toy, are made of special flattened wire.

History

In antiquity, jewelry often contains, in the form of chains and applied decoration, large amounts of wire that is accurately made and which must have been produced by some efficient, if not technically advanced, means. In some cases, strips cut from metal sheet were made into wire by pulling them through perforations in stone beads. This causes the strips to fold round on themselves to form thin tubes. This strip drawing technique was in use in Egypt by the 2nd Dynasty. From the middle of the 2nd millennium BC most of the gold wires in jewellery are characterised by seam lines that follow a spiral path along the wire. Such twisted strips can be converted into solid round wires by rolling them between flat surfaces or the strip wire drawing method. The strip twist wire manufacturing method was superseded by drawing in the ancient Old World sometime between about the 8th and 10th centuries AD. There is some evidence for the use of drawing further East prior to this period.

Gazelle Twin

Gazelle Twin is the stage name of Elizabeth Bernholz (née Walling), a British composer, producer and musician from Brighton, England.

Walling conceived the project when she watched Fever Ray perform at the 2009 Loop Festival. She noted how "her show reminded me how powerful and liberating costume is, and I became interested in the power of disguise".

Her debut album, The Entire City, was released in July 2011 to critical acclaim. The album includes her two previously recorded singles, "Changelings" (2010) and "I Am Shell I Am Bone" (2011). In 2014 Gazelle Twin released her second album, Unflesh, to further critical praise. She has also remixed music by John Foxx. She married the local musician Jez Bernholz who also performs with her on-stage.
