Bronze is a metal alloy consisting primarily of copper, usually with tin as the main additive. It is hard and brittle, and it was particularly significant in antiquity, so much so that the Bronze Age was named after the metal. However, since "bronze" is a somewhat imprecise term, and historical pieces have variable compositions, in particular with an unclear boundary with brass, modern museum and scholarly descriptions of older objects increasingly use the more cautious and inclusive term "copper alloy" instead.^[1]

The word bronze is borrowed from French: bronze, itself borrowed from Italian: bronzo (compare Medieval Latin: bronzium), whose origin is unclear. It might be connected with Venetian: bronza "glowing coals", or German: Brunst "fire", but it could equally go back to, or be influenced by, the Latin name Brundisium of the city of Brindisi (aes Brundusinum, meaning "copper of Brindisi", is attested in Pliny). However, perhaps it is ultimately taken from the Persian word for brass, birinj.^[2]

History[link]

The discovery of bronze enabled people to create metal objects which were better than previously possible. Tools, weapons, armor, and various building materials, like decorative tiles, made of bronze were harder and more durable than their stone and copper ("Chalcolithic") predecessors. Initially bronze was made out of copper and arsenic to form arsenic bronze. It was only later that tin was used, becoming the sole type of bronze in the late 3rd millennium BC. Tin bronze was superior to arsenic bronze in that the alloying process itself could more easily be controlled (as tin was available as a metal) and the alloy was stronger and easier to cast. Also, unlike arsenic, tin is not toxic.

The earliest tin-alloy bronzes date to the late 4th millennium BC in Susa (Iran) and some ancient sites in China, Luristan (Iran) and Mesopotamia (Iraq).

Copper and tin ores are rarely found together (exceptions include one ancient site in Thailand and one in Iran), so serious bronze work has always involved trade. In Europe, the major source for tin was Great Britain's deposits of ore in Cornwall, which were traded as far as Phoenicia in the Eastern Mediterranean.

Though bronze is generally harder than wrought iron, with Vickers hardness of 60–258^[3] vs. 30–80,^[4] the Bronze Age gave way to the Iron Age; this happened because iron was easier to find and easier to process. Bronze was still used during the Iron Age, for example officers in the Roman army had bronze swords^{[citation needed]} while foot soldiers had iron, but, for many purposes, the weaker wrought iron was found to be sufficiently strong. Archaeologists suspect that a serious disruption of the tin trade precipitated the transition. The population migrations around 1200–1100 BC reduced the shipping of tin around the Mediterranean (and from Great Britain), limiting supplies and raising prices.^[5] As ironworking improved, iron became cheaper; and as cultures advanced from wrought iron to forged iron, they learned how to make steel, which is stronger than bronze and holds a sharper edge longer.^[6]

Composition[link]

There are many different bronze alloys but modern bronze is typically 88% copper and 12% tin.^[7] Alpha bronze consists of the alpha solid solution of tin in copper. Alpha bronze alloys of 4–5% tin are used to make coins, springs, turbines and blades. Historical "bronzes" are highly variable in composition, as most metalworkers probably used whatever scrap was to hand; the metal of the 12th century English Gloucester Candlestick is bronze containing a mixture of copper, zinc, tin, lead, nickel, iron, antimony, arsenic with an unusually large amount of silver - between 22.5% in the base and 5.76% in the pan below the candle. The proportions of this mixture may suggest that the candlestick was made from a hoard of old coins. The Benin Bronzes are really brass, and the Romanesque Baptismal font at St Bartholomew's Church, Liège is described as both bronze and brass.

Commercial bronze (90% copper and 10% zinc) and Architectural bronze (57% Copper, 3% Lead, 40% Zinc) are more properly regarded as brass alloys because they contain zinc as the main alloying ingredient. They are commonly used in architectural applications.^[8][9]

Bismuth bronze is a bronze alloy with a composition of 52% copper, 30% nickel, 12% zinc, 5% lead, 1% bismuth. It is able to hold a good polish and so is sometimes used in light reflectors and mirrors.^[10]

Other bronze alloys include aluminium bronze, phosphor bronze, manganese bronze, bell metal, arsenical bronze, speculum metal and cymbal alloys.

Properties[link]

Assorted ancient bronze castings

Bronze is considerably less brittle than iron. Typically bronze only oxidizes superficially; once a copper oxide (eventually becoming copper carbonate) layer is formed, the underlying metal is protected from further corrosion. However, if copper chlorides are formed, a corrosion-mode called "bronze disease" will eventually completely destroy it.^[11] Copper-based alloys have lower melting points than steel or iron, and are more readily produced from their constituent metals. They are generally about 10 percent heavier than steel, although alloys using aluminium or silicon may be slightly less dense. Bronzes are softer and weaker than steel—bronze springs, for example, are less stiff (and so store less energy) for the same bulk. Bronze resists corrosion (especially seawater corrosion) and metal fatigue more than steel and is a better conductor of heat and electricity than most steels. The cost of copper-base alloys is generally higher than that of steels but lower than that of nickel-base alloys.

Copper and its alloys have a huge variety of uses that reflect their versatile physical, mechanical, and chemical properties. Some common examples are the high electrical conductivity of pure copper, the excellent deep drawing qualities of cartridge case brass, the low-friction properties of bearing bronze, the resonant qualities of bell bronze, and the resistance to corrosion by sea water of several bronze alloys.

The melting point of Bronze varies depending on the actual ratio of the alloy components and is about 950 °C (1,742 °F).

Bronze is nonmagnetic.

Uses[link]

Bronze was especially suitable for use in boat and ship fittings prior to the wide employment of stainless steel owing to its combination of toughness and resistance to salt water corrosion. Bronze is still commonly used in ship propellers and submerged bearings.

In the twentieth century, silicon was introduced as the primary alloying element, creating an alloy with wide application in industry and the major form used in contemporary statuary. Sculptors may prefer silicon bronze because of the ready availability of silicon bronze brazing rod, which allows color-matched repair of defects in castings. Aluminium is also used for the structural metal aluminium bronze.

It is also widely used for cast bronze sculpture. Many common bronze alloys have the unusual and very desirable property of expanding slightly just before they set, thus filling in the finest details of a mold. Bronze parts are tough and typically used for bearings, clips, electrical connectors and springs.

Spring bronze weatherstripping comes in rolls of thin sheets and is nailed or stapled to wood windows and doors. There are two types, flat and v-strip. It has been used for hundreds of years because it has low friction, seals well and is long lasting. It is used in building restoration and custom construction.

Bronze also has very low metal-on-metal friction, which made it invaluable for the building of cannon where iron cannonballs would otherwise stick in the barrel.^{[citation needed]} It is still widely used today for springs, bearings, bushings, automobile transmission pilot bearings, and similar fittings, and is particularly common in the bearings of small electric motors. Phosphor bronze is particularly suited to precision-grade bearings and springs. It is also used in guitar and piano strings.

Unlike steel, bronze struck against a hard surface will not generate sparks, so it (along with beryllium copper) is used to make hammers, mallets, wrenches and other durable tools to be used in explosive atmospheres or in the presence of flammable vapors.

Bronze is used to make bronze wool for woodworking applications where steel wool would discolor oak.

Bronze statues[link]

Indian Hindu artisans from the period of the Chola empire in Tamil Nadu, used bronze to create intricate statues via the lost wax casting method with ornate detailing depicting the Gods of Hinduism mostly, but also the lifestyle of the period. The art form survives to this day, with many silpis, craftsmen, working in the areas of Swamimalai and Chennai.

In antiquity other cultures also produced works of high art using bronze. For example: in Africa, the bronze heads of the Kingdom of Benin; in Europe, Grecian bronzes typically of figures from Greek mythology; in east Asia, Chinese bronzes of the Shang and Zhou dynasty — more often ceremonial vessels but including some figurine examples.

Bronze continues into modern times as one of the materials of choice for monumental statuary.

Musical instruments[link]

Bronze is the most popular metal for top-quality bells, particularly bell metal, which is about 23% tin.

Nearly all professional cymbals are made from a bronze alloy. The alloy used in drum kit cymbal bronze is unique in the desired balance of durability and timbre.

Modern cymbals consist of several types of bronze, the most common being B20 bronze, which is roughly 20% tin, 80% copper, with traces of silver. Zildjian and Sabian use this alloy for their professional lines. A Swiss company, Paiste, uses a tougher B8 bronze which is made from 8% tin and 92% copper in the majority of their cymbals. Zildjian and Sabian use this metal too, in their budget priced cymbals. Paiste also use a secret Bronze alloy in their top-end cymbal ranged, thought to be B12 or B14, adding brightness without much compromise on strength^{[citation needed]}

As the tin content in a bell or cymbal rises, the timbre drops.^[12] As well as B8 and B20, Meinl Percussion uses B10 (10% tin) and B12 (12% tin) alloys for cymbals, which have timbres roughly between B8 and B20.^[13]

Bronze is also used for the windings of steel and nylon strings of various stringed instruments such as the double bass, piano, harpsichord, and the guitar.. Bronze strings are commonly reserved on pianoforte for the lower pitch tones, as they possess a superior sustain quality to that of high-tensile steel.^[14]

Bronzes of various metallurgical properties are widely used in struck idiophones around the world, notably bells, singing bowls, gongs, cymbals and other idiophones from Asia. Examples include Tibetan singing bowls, temple bells of many sizes and shapes, gongs, Javanese gamelan and other bronze musical instruments. The earliest bronze archeological finds in Indonesia date from 1–2 BCE, including flat plates probably suspended and struck by a wooden or bone mallet.^[14][15] Ancient bronze drums from Thailand and Vietnam date back 2,000 years. Bronze bells from Thailand and Cambodia date back to 3,600 BCE.

Some companies are now making saxophones from phosphor bronze (3.5 to 10% tin and up to 1% phosphorus content). Bell Bronze is used to make the tone rings of many professional model banjos. The tone ring is a heavy(usually 3 lbs.) folded or arched metal ring attached to a thick wood rim, over which a skin, or most often, a plastic membrane(or head)is stretched-it is the bell bronze that gives the banjo a crisp powerful lower register and clear, bell-like treble register-especially in bluegrass music.

Medals[link]

Bronze has been used in the manufacture of various types of medals for centuries, and are known in contemporary times for being awarded to the second-runner up in sporting competitions and other events. The later usage was in part attributed to the choices of Gold, Silver and Bronze to represent the first three Ages of Man in Greek mythology: the Golden Age, when men lived among the gods; the Silver age, where youth lasted a hundred years; and the Bronze Age, the era of heroes, and was first adopted at the 1904 Summer Olympics. At the 1896 event, silver was awarded to winners and bronze to runners-up, while at 1900 other prizes were given, not medals.

Robin Charles Thicke ( /ˈθɪk/; born March 10, 1977) is an American R&B singer-songwriter, musician, composer, and actor. Thicke's albums, which he previously released under the name Thicke, are noted for their feature of a predominantly R&B sound.^[1][2] Thicke has written hits for popular artists such as Jennifer Hudson, Usher, Mary J. Blige and Raven-Symoné. Thicke has also been acknowledged for his work in popular albums such as Confessions and Tha Carter III.

Thicke is a judge on the ABC show Duets.^[3]

Career[link]

Early years[link]

Before his days as a singer-songwriter, Thicke had written "Love Is On My Side" on Brandy's self-titled album and a number of songs for 3T's "Sexual Attention" and collaborated with Jordan Knight, Jimmy Jam and Terry Lewis on several songs in Knight's 1999 album Jordan Knight. He also co-wrote the songs "When You Put Your Hands On Me" for Christina Aguilera's debut album and "No Tears on My Pillow" for Mýa's sophomore release, Fear of Flying. As an artist, he recorded and performed solely under his surname, Thicke. He would continue to do so until 2005.

2002–2004: Early commercial success[link]

In 2000, Thicke, who simply went by his last name, went to work on material for his debut album, initially titled Cherry Blue Skies. The album focused more on soul than his pop-offerings for other artists.

In 2002, Thicke released his debut single "When I Get You Alone". The track samples Walter Murphy's "A Fifth of Beethoven", which itself is a disco rendition of Beethoven's Fifth Symphony. The music video for the song received some rotation on MTV2 and BET's Rated Next and was spun moderately on pop and urban radio, peaking at #49 on Radio & Records Pop chart.^{[citation needed]} Globally, however, "When I Get You Alone" became a chart success when it peaked within the top 20 in Australia, Belgium, and Italy, and reached the top ten of the singles charts in New Zealand and the top three in the Netherlands.^{[citation needed]} The tune was featured for the soundtrack of Agent Cody Banks.^{[citation needed]}

The moderate success was enough to signal the release of the album, with its name changed to A Beautiful World. Despite the release of a second single, "Brand New Jones", the album received very little promotion, and debuted at a low number 152 on the US Billboard 200, eventually selling 63,000 copies.^[4]

Runner-up Blake Lewis performed "When I Get You Alone" during the 2007 season of American Idol when the top 3 chose a song to sing. Lewis has often put Robin Thicke in his list of musical influences in interviews and on the American Idol website. The song was also performed by Blaine Anderson (played by Darren Criss) on Glee during the season 2 episode "Silly Love Songs".^{[citation needed]}

[edit] 2005–2007: The Evolution of Robin Thicke

In 2005, Thicke performed as a guest on the remix of Will Smith's song, "Switch". After being signed to The Neptunes label, Star Trak, he began working on his second album entitled The Evolution of Robin Thicke. The first single, "Wanna Love U Girl", featured producer Pharrell and experienced chart success on urban radio in the United Kingdom. For the video, Thicke changed his appearance, cutting off his trademark long hair. In 2006, a remix version of the song was filmed with rapper Busta Rhymes. Nearly a year after the single was released, the album was released on October 3, 2006. To promote the album Thicke toured with India.Arie, and then opened for John Legend in late 2006.

His second single, the ballad "Lost Without U", began getting a lot of radio airplay in Urban & Rhythmic stations towards the end of 2006 and early 2007.^{[citation needed]} With the assistance of radio airplay, the song became his breakout hit, reaching as high as number fourteen on the Billboard Hot 100, and number one on the Billboard Hot R&B/Hip-Hop Songs, the first Caucasian male artist to top that chart since George Michael.^[5] With album sales over 1.5 million copies sold domestically after the re-release as a Deluxe Edition (with three new bonus tracks) on February 13, 2007, The Evolution of Robin Thicke became a commercial success in the United States.^{[citation needed]}

The album peaked at number five on the Billboard 200 and number one on the Billboard Top R&B/Hip-Hop Albums chart,^[4] garnering Thicke his first R&B number one album of his career. In early 2007 the single "Lost Without U" and album The Evolution of Robin Thicke simultaneously spent two consecutive weeks at number one on the R&B singles and albums charts respectively. On the March 3, 2007 issue of Billboard magazine, Thicke simultaneously topped four Billboard charts; Top R&B/Hip-Hop Albums, Hot R&B/Hip-Hop Songs, Hot R&B/Hip-Hop Airplay, and Hot Adult R&B Airplay.^{[citation needed]} In March 2007, The Evolution of Robin Thicke was certified Platinum by the RIAA.^{[citation needed]} Thicke and his record label Interscope soon considered potential tracks to be released as the album's next and third single. Thicke's preference was the track "Can U Believe", which peaked at number fifteen on the Billboard Hot R&B/Hip-Hop Songs and at number ninety-nine on the Billboard Hot 100 chart.^[5][6] On October 2, 2007 the track "Got 2 Be Down" was released as the album's fourth official single. The single peaked at number sixty on Billboard's Hot R&B/Hip-Hop Singles & Tracks.^[5]

Late in 2007, Thicke finished promotion for the album as the featured opening act for the North American leg of Beyoncé's US tour, The Beyoncé Experience.^[7] Thicke also performed a one off UK concert in London's Koko Arena on September 24, 2007. As of February 10, 2009, the album was certified Double-Platinum by the RIAA.

[edit] 2008–10: Something Else and Sex Therapy

There's so many meanings behind that title. Number one, it reflects what we're going through as a nation here in America. I just felt, with Barack Obama and the new energy he's bringing, that it is time for some fresh hope and new attitudes. Then, in terms of me as an artist, because I'd been singing all these songs about self-reflection - like '2 The Sky' and 'Angels' - I just thought it was time for me to start singing about something ELSE! Also, I felt that - with my music being a little different from everything else you can get out there - the music IN ITSELF is also something different and something else!"

—Robin Thicke interview by Pete Lewis, Blues & Soul, November 2008.[8]

Thicke released his third solo album, entitled Something Else, on September 30, 2008.^{[citation needed]} It debuted at number three on the Billboard 200 charts and sold nearly 140,000 records the first week.^{[citation needed]} The first single from the album was "Magic" a further expansion of the R&B sound that powered his 2006 breakthrough, The Evolution of Robin Thicke.^{[citation needed]} "Magic" went on to peak at number two on the Urban AC charts.^{[citation needed]} He followed this success with the second single, "The Sweetest Love", which also peaked at number two on the Urban AC charts and remained in the top five for twelve consecutive weeks.^{[citation needed]}

During an interview to promote his third album, Thicke explained:

Thicke appeared on an episode of ABC's The Bachelor to perform “Magic” and “The Sweetest Love” for the remaining female contestants. Thicke wrote and produced a track for the movie Precious in which his wife Paula Patton also starred.^[10] He co-headlined a U.S. tour with Jennifer Hudson, which began March 31, 2009 in Albany, New York, and wrapped up 25 shows later in Biloxi, Mississippi.^[11] At the start of the tour, Thicke released "You're My Baby" as the official third single from Something Else, despite filming and releasing a music video for the track "Dreamworld".^[11] As of April 2009, Something Else has shifted over 435,000 units in the U.S.

Seven months after the release of Something Else, Billboard.com announced that Thicke would release his fourth studio album in the fall of 2009, which would not be self-produced.^[11] The album, titled Sex Therapy, had its release date postponed to winter, on December 15, 2009. Jay-Z is featured on the track "Meiple (Me I Play)". The first single from the album was the self-titled track, produced by Polow Da Don and released in October 2009. In November 2009, Thicke premiered the second single to radio, "Shakin' It for Daddy", featuring rapper Nicki Minaj. It was also produced by Polow Da Don.

Speaking of the musical background to Sex Therapy, Thicke told Pete Lewis - Deputy Editor of Blues & Soul - "I'm always gonna have the influence of Marvin Gaye, Stevie Wonder and Al Green in my music. But with this album I also wanted to show my HIP HOP side. I grew up listening to Run DMC and NWA and Biggie and Pac and Jay-Z... So I really wanted to make a record that represented how much that music has influenced me."^[12] Earlier in 2009, on October 14, Leighton Meester's debut single "Somebody to Love", featuring Thicke, was released. Thicke told MTV he was glad to have Lil Wayne on the album. He also pointed out that he was featured on Lil Wayne's last two albums, and Lil Wayne was on his last two albums. "We're kind of good luck charms for each other."^{[citation needed]}

Thicke appeared on ABC's New Year's Rockin' Eve on January 1, 2010 and performed three songs in Las Vegas, in a pre-recorded segment. Also in 2010, it was confirmed that he, along with Melanie Fiona, would feature on The Freedom Tour with Alicia Keys. As of October 2011, the album has sold 269,000 copies in the United States.^[13]

[edit] 2011–present: Love After War

During 2011, Thicke was confirmed to go on tour with Jennifer Hudson, with whom he toured in 2009.^[14] Later that year, Robin Thicke released his fifth studio album, Love After War, on December 6, 2011.^[15] The album has produced two singles. There is the title track and lead single, "Love After War". The second single is "Pretty Lil' Heart", which features Lil Wayne. Robin Thicke appeared on ABC's New Year's Rockin' Eve 2012 performing via remote feed from Los Angeles, California.^{[citation needed]}

Thicke is appearing as a judge on a new ABC television show called Duets which premiered May 24, 2012 and which also features John Legend, Jennifer Nettles, and Kelly Clarkson.^[3]

Artistry[link]

Songwriting and producing[link]

Thicke began his songwriting career by writing hits for popular artists. He co-wrote and produced the Color Me Badd hit "Sexual Capacity" in 1996. The Thicke original "When I Get You Alone" was performed by Guy Sebastian, the winner of the first Australian Idol 2003, during the competition and at the Idol grand finale. "When I Get You Alone" was a popular song choice for Sebastian; he put the live idol performance on his four-times platinum debut single "Angels Brought Me Here"; it was the fastest selling single in Australia debuting at #1 and immediately breaking an Aria record.^[16] In 2004, Thicke co-wrote "Out With My Baby" with Guy Sebastian, from Sebastian's second album, Beautiful Life. Thicke also produced this single for Sebastian.^[17] During this same year, he wrote a song with the singer and actress Raven-Symoné for the album This Is My Time, with the song "Set Me Free".

In April 2007, Thicke co-wrote a song with singer/songwriter Angela Via called "Wrong for You". In 2008, Thicke was enlisted by producer Polow da Don to play piano on the Usher track, "Love in This Club".^[18] At the 2009 Grammy Awards, Thicke was recognized for his work on Lil Wayne’s sixth studio album Tha Carter III, as well as Jennifer Hudson’s self titled debut album. Thicke wrote and produced the song "Tie My Hands" on Tha Carter III, which went on to win Best Rap Album. Thicke wrote and produced the song "Giving Myself" for the album Jennifer Hudson, which went on to win Best R&B Album.

Collaborations[link]

In 2007, Thicke appeared on 50 Cent's album Curtis, which was released on September 11, 2007, on a song called "Follow My Lead". The following year, he worked with Ashanti on her fourth studio album, The Declaration, which was released on June 3, 2008.^[6][7] Also that year, Thicke reunited with Lil Wayne and was featured on his album Tha Carter III on a track entitled "Tie My Hands", which Thicke also produced.
