Natron
Natron is a naturally occurring mixture of sodium carbonate decahydrate ( Na2CO3·10H2O, a kind of soda ash) and around 17% sodium bicarbonate (also called baking soda, NaHCO3) along with small quantities of sodium chloride and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities. Natron deposits are sometimes found in saline lake beds which arose in arid environments. Throughout history natron has had many practical applications that continue today in the wide range of modern uses of its constituent mineral components. In modern mineralogy the term ''natron'' has come to mean only the sodium carbonate decahydrate (hydrated soda ash) that makes up most of the historical salt. Etymology The English and German word ''natron'' is a French cognate derived from the Spanish ''natrón'' through Latin ''natrium'' and Greek ''nitron'' (). This derives from the Ancient Egyptian word ''nṯrj''. ''Natron'' refers to Wadi El Natrun or Natr ...

Natron (software)
Natron is a free and open-source node-based compositing application. It has been influenced by digital compositing software such as Avid Media Illusion, Apple Shake, Blackmagic Fusion, Autodesk Flame and Nuke, from which its user interface and many of its concepts are derived. Natron supports plugins following the OpenFX 1.4 API. Most open-source and commercial OpenFX plug-ins are supported. Origin of the name Natron is named after Lake Natron in Tanzania which, according to Natron lead programmer Alexandre Gauthier, provides "natural visual effects" by preserving its dead animals. History Natron was started by Alexandre Gauthier in June of 2012 as a personal project. The project was the winner of the 2013 ''Boost Your Code'' contest by Inria. The prize was a 12-month employment contract to develop Natron as a free and open-source software within the institute. The first widely available public release was 0.92 (June 6th, 2014), which brought rotoscoping and chroma keying ...

Lake Natron
Lake Natron is a salt or alkaline lake located in north Ngorongoro District of Arusha Region in Tanzania. It is in the Gregory Rift, which is the eastern branch of the East African Rift. The lake is within the Lake Natron Basin, a Ramsar Site wetland of international significance. The lake is fed principally by the Southern Ewaso Ng'iro River, which rises in central Kenya, and by mineral-rich hot springs. It is quite shallow, less than deep, and varies in width depending on its water level. The lake is a maximum of long and wide. The surrounding area receives irregular seasonal rainfall, mainly between December and May totalling per year. Temperatures at the lake are frequently above . High levels of evaporation have left behind natron (sodium carbonate decahydrate) and trona (sodium sesquicarbonate dihydrate). The alkalinity of the lake can reach a pH of greater than 12. The surrounding bedrock is composed of alkaline, sodium-dominated trachyte lavas that were laid down ...
