Chemistry is interested in the composition of all the substances that make up our universe, their properties and their transformations. Chemists seek to better understand how our world works. Chemistry is subdivided into several major areas such as analytical, environmental, organic or inorganic chemistry, physical chemistry and many more. Chemistry has served the world of art! it is illustrated in several fields, pigments, chemical progress constantly improves them, photography, it is thanks to Daguerre, Niecpe and Arago that we fixed an image on paper. The expertise of works of art is also covered by conservation and restoration scientists who are often organic chemists or pros in the chemistry of matter. The IR and UV spectra can show us the inside of a statute or writings hidden under the repaints of paintings... Finally, art and science come from Technè and it's not for nothing. Hoping at the end to have new chemistry enthusiasts.
