Ammonia
Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals and is used in many commercial cleaning products. Although common in nature and in wide use, ammonia is both caustic and hazardous in its concentrated form.
The global industrial production of ammonia for 2012 was anticipated to be 198,000,000 tonnes (195,000,000 long tons; 218,000,000 short tons), a 35% increase over the estimated 2006 global output of 146,500,000 tonnes (144,200,000 long tons; 161,500,000 short tons).
NH3 boils at −33.34 °C (−28.012 °F) at a pressure of one atmosphere, so the liquid must be stored under pressure or at low temperature. Household ammonia or ammonium hydroxide is a solution of NH3 in water. The concentration of such solutions is measured in units of the Baumé scale (density), with 26 degrees baumé (about 30% (by weight) ammonia at 15.5 °C or 59.9 °F) being the typical high-concentration commercial product.

Ufomammut
Ufomammut (Italian pronunciation: [ufomamˈmut]) is an Italian psychedelic metal band.
History
Hailing from Italy, Ufomammut is a psychedelic sludge metal trio formed in 1999 in Italy by Poia, Urlo and Vita. The band has cultivated a unique sound by playing lengthy songs built on heavily repeated riffs with droning vocals and a large use of effects and sound manipulation. The band's music is based largely on long sludgy riffs reminiscent of Electric Wizard and a heavy use of psychedelic effects.
Ufomammut released their first album, Godlike Snake, under Beard of Stars Records in 2000. This was followed in 2004 by the release of Snailking, their second full-length release. Snailking was subsequently reissued by Supernatural Cat Records in 2009. In 2007 the band recorded Supernaturals: Record One with Lento. Ufomammut's fourth album, Idolum was released in 2008.
In 2010 the band released Eve, their fifth album. Eve consists of one 45-minute atmospheric track, divided into five distinctive movements; it depicts Eve as a figure reminiscent of both Lucifer (in her rebellion against God) and Prometheus (in bringing knowledge to humanity). At 44:44, the album is similar to Idolum, layered with sludgy heavy riffing and yet also bearing some of the calmer, more reflective passages found on their Lucifer Songs LP.
