Plaster is a building material similar to mortar or cement. Like those materials, plaster starts as a dry powder that is mixed with water to form a paste which liberates heat and then hardens. Unlike mortar and cement, plaster remains quite soft after setting, and can be easily manipulated with metal tools or even sandpaper. These characteristics make plaster suitable for a finishing, rather than a load-bearing material.
The term plaster can refer to gypsum plaster (also known as ''plaster of Paris''), lime plaster, or cement plaster.
:2 CaSO4·2H2O → 2 CaSO4·0.5H2O + 3 H2O (released as steam).
When the dry plaster powder is mixed with water, it re-forms into gypsum.
A large gypsum deposit at Montmartre in Paris led gypsum plaster to be commonly known as "plaster of Paris".
One of the skills used in movie and theatrical sets is that of "plasterer", gypsum plaster often being used to simulate the appearance of surfaces of wood, stone, or metal. Nowadays, plasterers are just as likely to use expanded polystyrene, although the job title remains unchanged.

To make lime plaster, limestone (calcium carbonate) is heated to produce quicklime (calcium oxide). Water is then added to produce slaked lime (calcium hydroxide), which is sold as a white powder. Additional water is added to form a paste prior to use. The paste may be stored in air-tight containers. Once exposed to the atmosphere, the calcium hydroxide turns back into calcium carbonate, causing the plaster to set.
Lime plaster was a common building material for wall surfaces in a process known as lath and plaster, whereby a series of wooden strips on a studwork frame was covered with a semi-dry plaster that hardened into a surface. The plaster used in most lath and plaster construction was mainly lime plaster, with a cure time of about a month. To stabilize the lime plaster during curing, small amounts of plaster of Paris were incorporated into the mix. Because plaster of Paris sets quickly, "retardants" were used to slow setting time enough to allow workers to mix large working quantities of lime putty plaster. A modern form of this method uses expanded metal mesh over wood or metal structures, which allows a great freedom of design as it is adaptable to both simple and compound curves. Today this building method has been partly replaced with drywall, also composed mostly of gypsum plaster. In both these methods a primary advantage of the material is that it is resistant to a fire within a room and so can assist in reducing or eliminating structural damage or destruction provided the fire is promptly extinguished.
Lime plaster is used for true frescoes. Pigments, diluted in water, are applied to the still wet plaster.
Plaster may be cast directly into a damp clay mold. In creating this ''piece molds'' (molds designed for making multiple copies) or ''waste molds'' (for single use) would be made of plaster. This "negative" image, if properly designed, may be used to produce clay productions, which when fired in a kiln become terra cotta building decorations, or these may be used to create cast concrete sculptures. If a plaster positive was desired this would be constructed or cast to form a durable image artwork. As a model for stonecutters this would be sufficient. If intended for producing a bronze casting the plaster positive could be further worked to produce smooth surfaces. An advantage of this plaster image is that it is relatively cheap; should a patron approve of the durable image and be willing to bear further expense, subsequent molds could be made for the creation of a wax image to be used in lost wax casting, a far more expensive process. In lieu of producing a bronze image suitable for outdoor use the plaster image may be painted to resemble a metal image; such sculptures are suitable only for presentation in a weather-protected environment.
Plaster expands while hardening, then contracts slightly just before hardening completely. This makes plaster excellent for use in molds, and it is often used as an artistic material for casting. Plaster is also commonly spread over an armature (form), usually made of wire, mesh or other materials, a process raised details. For these processes, limestone or acrylic based plaster may be employed.
Plaster is also used within radiotherapy when making immobilization casts for patients. Plaster bandages are used when constructing an impression of the patients head and neck, and liquid plaster is used to fill the impression and produce a plaster bust. Perspex is then vacuum formed over this bust creating an immobilization shell.
In dentistry, plaster is used for mounting casts or models of oral tissues. These diagnostic and working models are usually made from dental stone, a stronger, harder and denser derivative of plaster which is manufactured from gypsum under pressure. Plaster is also used to invest or flask wax dentures, the wax being subsequently removed and replaced with the final denture base material which is cured in the plaster mold.
The finished plaster releases water vapor when exposed to flame, acting to slow the spread of the fire, for as much as an hour or two depending on thickness. It also provides some insulation to retard heat flow into structural steel elements, that would otherwise lose their strength and collapse in a fire. Early versions of these plasters have used asbestos fibres, which have by now been outlawed in industrialized nations and have caused significant removal and re-coating work. More modern plasters fall into the following categories:
One differentiates between interior and exterior fireproofing. Interior products are typically less substantial, with lower densities and lower cost. Exterior products have to withstand more extreme fire and other environmental conditions. Exterior products are also more likely to be attractively tooled, whereas their interior cousins are usually merely sprayed in place. A rough surface is typically forgiven inside of buildings as dropped ceilings often hide them. Exterior fireproofing plasters are losing ground to more costly intumescent and endothermic products, simply on technical merit. Trade jurisdiction on unionized construction sites in North America remains with the plasterers, regardless of whether the plaster is decorative in nature or is used in passive fire protection. Cementitious and gypsum based plasters tend to be endothermic. Fireproofing plasters are closely related to firestop mortars. Most firestop mortars can be sprayed and tooled very well, due to the fine detail work that is required of firestopping, which leads their mix designers to utilise concrete admixtures, that enable easier tooling than common mortars.
Some variations of plaster that contain powdered silica or asbestos may present health hazards if inhaled. Asbestos is a known irritant when inhaled in powder form can cause cancer, especially in people who smoke, and inhalation can also cause asbestosis. Inhaled silica can cause silicosis and (in very rare cases) can encourage the development of cancer. Persons working regularly with plaster containing these additives should take precautions to avoid inhaling powdered plaster, cured or uncured. (Note that asbestos is rarely used in modern plaster formulations because of its carcinogenic effects.)

She moved back to her parents’ house in New Jersey in 2004, working odd jobs and playing local gigs. During a regular Friday night stand at Kelly’s Tavern in nearby Neptune City, the audience kept requesting cover songs by local favorites Bruce Springsteen and Jon Bon Jovi. In response, Atkins got drunk and played a tongue-in-cheek version of Bon Jovi’s “Livin' on a Prayer”. She was not asked back.
During this time, she commuted into New York by train to play gigs and maintain a connection to the city’s underground music scene. In mid-2004, Atkins and David Muller, who had played drums with Fischerspooner and The Fiery Furnaces, started working on a demo CD entitled ''Party’s Over''. They recorded most of the album in Atkins’ parents’ house using a Casio keyboard, a ProTools rig, and a mini recorder. Drum parts were recorded at Muller’s apartment in Manhattan, with further tracks recorded at the Dietch Projects gallery in Brooklyn.
In January 2010, Atkins and The Black Sea started recording new material at Brooklyn's Seaside Lounge studio with producer Phil Palazzolo, with whom Atkins had previously worked during sessions for A.C. Newman's second solo album, ''Get Guilty''. Several other musicians joined Atkins in the studio to record the tracks for what would become her second album, ''Mondo Amore'', including guitarist Irina Yalkowsky and bassist Jeremy Kay. Along with drummer Ezra Oklan, Yalkowsky and Kay would form the core lineup of the The Black Sea with whom Atkins would tour in support of ''Mondo Amore''. In June 2010, Atkins signed with New York-based independent label Razor & Tie. The label released ''Mondo Amore'' on February 8, 2011.
Atkins also joined the 9th annual Independent Music Awards judging panel to assist independent musicians' careers.
When not on the road, she lives in Brooklyn, New York.

Her stage name, "Marina and the Diamonds", consists of Diamandis's first name and the translation of her surname which means "Diamonds" in Greek. Although "The Diamonds" is often mistakenly believed to refer to her backing band, it in fact refers to Diamandis's fans: she explains this on her Myspace page by saying "I'm Marina Diamandis. You are my fans."
Diamandis's musical style ranges from keyboard-based ballads to more up-tempo New Wave-style songs with full band backing. She has cited a wide-range of influences such as Daniel Johnston, Blondie, The Distillers, Patti Smith, Tom Waits, Nirvana, PJ Harvey, Yann Tiersen, Elliott Smith, Dolly Parton and Madonna.
Diamandis moved to London at the age of eighteen where she attended dance school for only two months. Following this, in 2005 she took a one year singing course at Tech Music Schools. Diamandis enrolled on a degree in music at the University of East London, transferring in her second year of studies to Middlesex University, but she later dropped out. She went for many auditions including the West End musical, ''The Lion King''. Diamandis admitted that she auditioned for a reggae boy band, held by Virgin Records, in 2005 to try to make it into the music business. She said she was "delusional with drive" and ultimately decided to dress up in male attire to try to amuse the record label to sign her, but she was unsuccessful. However, she was called back by the record label a week later.
Diamandis has a synaesthetic condition that involves seeing musical notes and days of the week in different colours.
Early demos of Marina and the Diamonds' songs were self composed and produced on the Apple software application Garageband. Through Gumtree she found someone to produce a few tracks, for which she paid £500. These ended up on her debut extended play ''Mermaid Vs. Sailor EP'' which was released on 23 November 2007. The record was created on hand-made CD-Rs by Diamandis and sold through her MySpace page. An estimated seventy copies were sold overall.
In January 2008, Diamandis was first discovered by music scouter Derek Davies of Neon Gold Records. Davies booked Diamandis to open for Australian singer Gotye later that year where Warner Music Group first saw her and ended up signing her in October 2008 to 679 Recordings. Diamandis's debut single was a double a-side consisting of "Obsessions" and "Mowgli's Road" which was issued on Neon Gold Records in the United States on 19 November 2008, followed by her second extended play ''The Crown Jewels EP'' on 1 June 2009 featuring her second single "I Am Not a Robot". Her first major label single, a re-recording of "Mowgli's Road", was released on 13 November 2009 under 679 Recordings in the UK and through Atlantic Records in the USA. On 7 December 2009 she was listed on the longlist for the BBC Sound of 2010 poll, and on 7 January 2010 it was announced that she had taken second place.
Early on in 2010, Diamandis has been collaborating with producer Benny Blanco and guitarist Dave Sitek in Los Angeles on new material which she describes to be "a really great opportunity for me as a songwriter. [We are] such a weird threesome - a combination of super pop and really indie".
In March 2010, Atlantic Records signed Marina and the Diamonds to Chop Shop Records in the United States. Before the album's American release on 25 May 2010, Diamandis released her third extended play, ''The American Jewels EP'', digitally and exclusively for the United States on 23 March 2010. Diamandis made her North American debut on 14 March 2010 through a series of performances.
Marina and the Diamonds was nominated for Critics' Choice at the 2010 BRIT Awards and came fifth in ''SHREDnews''
On 8th August 2011 at 4pm, Diamandis uploaded a new video to her Youtube page titled "Part 1: Fear & Loathing". In an interview with Popjustice, Marina explained the whole concept of "Electra Heart" with the album to be under the same title and "Fear & Loathing" as an album track, and to be released on iTunes on September the 25th. However this will not be an official single. The high concept video for it sees Marina slowly transforming into the character of Electra Heart, a guise Marina says "epitomises and embodies the lies, illusions and death of American ideologies involved in the corruption of self." but will however not be an alter-ego as Marina says it is too "clichéd". Asked to describe just what Electra Heart is and stands for, Marina told Popjustice: "Electra Heart is the antithesis of everything that I stand for. And the point of introducing her and building a whole concept around her is that she stands for the corrupt side of American ideology, and basically that’s the corruption of yourself. My worst fear - that’s anyone’s worst fear - is losing myself and becoming a vacuous person. And that happens a lot when you’re very ambitious." The second song, 'Radioactive' produced by Stargate premiered on BBC Radio 1 on 22 August 2011. It is set to be released on iTunes on 3rd October 2011. Further developing the Electra Heart concept "Part 2: Radioactive" the official music video for the single premiered.
Aside from music, Diamandis became the new face of Max Factor. The venture was confirmed early 2011 with a number of photoshoots since taking place.
Diamandis calls herself a "DIY musician" and describes her sound as an alternative to mainstream pop music. In an interview with ''ClashMusic'' Diamandis said that she does not come from a musical background and explained “I probably have a bit of a different sound because I don’t really know what I’m doing”. Lyrically, she says her music analyzes people and that if she wasn't a musician, she would be a psychologist.
Critics usually catalogue Marina and the Diamonds as a New Wave pop artist. In an interview with ''The Guardian'' she said, "I suppose I'm an indie artist with pop goals". Although Diamandis has urged that she never tries to sound like any other artist or copy a genre of music, she has been compared to a variety of artists such as Kate Bush and most commonly Florence and the Machine. ''PopMatters'' commented on her vocal delivery and attitude saying it "has a tendency to overshadow the music, which is often melodically inventive, but we are rarely given the chance to realise this." ''The Guardian''
As part of Selfridges' "Sound of Music", Diamandis designed her own window display for the London's Oxford Street branch in May 2010. She also appeared as a "live mannequin" for the display. Marina was featured on VOGUE.CO.UK throughout November 2010 for a popular sartorial section called Today I'm Wearing - where she blogged her daily style choices for the fashion website. On 20 December 2010, Diamandis announced on her Twitter that she would be the new face of the new make up range "Max Factor Max Colour Effects" and performed an intimate gig at London's Cuckoo Club.

In promotion for her album and "Hollywood", Diamandis performed at Brand New: 10 for 10 at London's Dingwalls, had an eleven minute 4Music special - ''4Play: Marina and the Diamonds'' - on Channel 4, performed at T4's Outside-In Festival, New to Q Sessions in January 2010, was a musical guest on GMTV, ''Friday Night with Jonathan Ross'', ''The Review Show'' in February, 2010 and ''Later... with Jools Holland'' and T4's ''Frock Me!'' in April, 2010. She performed at the Isle of Wight Festival 2010 and Glastonbury Festival 2010 in June 2010 and is planned to appear at other music festivals across the United Kingdom, mainland Europe and North America.
Diamandis had already sold out the first leg of her first headlining tour, The Family Jewels Tour (including the third leg of her tour, The Gem Tour) before the release of her debut album. Her entire tour currently consists of seventy dates across six legs around the United Kingdom, North America, Ireland and mainland Europe. Diamandis was accompanied by support acts Clock Opera and Alan Pownall for the first leg of her tour and Spark on The Gem Tour.
