Indigo in the context of "Denim"

Indigo dye is an organic compound with a distinctive blue color. Indigo is a natural dye obtained from the leaves of some plants of the Indigofera genus, in particular Indigofera tinctoria. Dye-bearing Indigofera plants were once common throughout the world. It is now produced via chemical routes from aniline. Blue colorants are rare. Since indigo is insoluble, it is also referred to as a pigment (C.I. Pigment Blue 66, C.I.).

Most indigo dye produced today is synthetic, constituting around 80,000 tonnes each year, as of 2023. It is most commonly associated with the production of denim cloth and blue jeans, where its properties allow for effects such as stone washing and acid washing to be applied quickly.

Indienne (/ˌændiˈɛn/, an-dee-EN; French: [ɛ̃.djɛn], lit. 'that which comes from Eastern India'), was a type of printed or painted textile manufactured in Europe between the 17th and the 19th centuries, inspired by similar textile originally made in India (hence the name). They received various other names in French such as madras, pékin (French for Peking), perse (French for Persia), gougouran, damas, and cirsacs. The original Indian techniques for textile printing involved long and complicated processes necessitating the use of mordants or metallic salts to fix the dyes. The beautiful, vibrant, colors came from the garance plant for red, indigo for blue, and gaude for yellow.

Indiennes were extremely popular, and attempts at import substitution were soon made. In 1640, Armenian merchants introduced Indian textile printing techniques at the port of Marseilles. Later, England (1670) and Holland (1678) would also adopt the technique.

Indium is a chemical element; it has symbol In and atomic number 49. It is a silvery-white post-transition metal and one of the softest elements. Chemically, indium is similar to gallium and thallium, and its properties are largely intermediate between the two. It was discovered in 1863 by Ferdinand Reich and Hieronymous Theodor Richter by spectroscopic methods and named for the indigo blue line in its spectrum.

Indium is used primarily in the production of flat-panel displays as indium tin oxide (ITO), a transparent and conductive coating applied to glass. It is also used in the semiconductor industry, in low-melting-point metal alloys such as solders and soft-metal high-vacuum seals. It is used in the manufacture of blue and white LED circuits, mainly to produce Indium gallium nitride p-type semiconductor substrates. It is produced exclusively as a by-product during the processing of the ores of other metals, chiefly from sphalerite and other zinc sulfide ores.

Georgetown is the third oldest city in the U.S. state of South Carolina and the county seat of Georgetown County, in the Lowcountry. As of the 2020 census it had a population of 8,403, a decrease from the 2010 census of 9,163. Located on Winyah Bay at the confluence of the Black, Great Pee Dee, Waccamaw, and Sampit rivers, Georgetown is the second largest seaport in South Carolina, handling over 960,000 tons of materials a year, while Charleston is the largest.

Beginning in the colonial era, Georgetown was the commercial center of an indigo- and rice-producing area. Rice replaced indigo as the chief commodity crop in the antebellum era. A timber industry also developed and sawmills were built.

Prinsep may mean any of several notable members of the British Prinsep family.

The family descended from John Prinsep, an 18th-century merchant who was the son of Rev. John Prinsep, rector of Saundby, Nottinghamshire, and Bicester, Oxfordshire. John Prinsep, his son, founded indigo production in India as well as the making of cotton fabrics in Bengal, opened a copper mint in India and was a founder of the Westminster Life Insurance Society in London, where he later served as Alderman and in Parliament. Prinsep arrived in India as a soldier in the army of the East India Company but became a merchant soon afterwards. During his 16 years in India, John Prinsep amassed a £40,000 fortune, which he used to set himself up as a London businessman and get himself elected to Parliament. Prinsep made two large fortunes and lost both. He was the first of three succeeding generations of Prinseps in India, all of whom were known for their artistic abilities. Among his descendants are the artist Valentine Cameron Prinsep, the Anglo-Indian antiquarian, scholar and architect James Prinsep.
