Where Does Ink Come From?
Video Transcript Where Does Ink Come From? Where does ink come from? Well obviously ink in many many forms has been around for quite some time, thousands of years in fact. Early Chinese illustrators, I guess for lack of a better word, used to get their ink from different types of soot, from fire combined with certain foods and from different animal skins and carcasses and could write or draw using that. Today ink basically is a combination of different types of pigments, dyes and it’s used for many many things obviously in the world we live in, not just for writing but for you know, coloring the clothes we wear and basically anything that involves some form of color in this day and age, on either printed materials or clothing or anything, comes from a certain form of ink. Ink is, I guess you could say, comprised primarily from solvents, pigments, dyes, resins, lubricants, many many many materials that when put together obviously create a form of colored dye, essentially that we can con
From a previous Yahoo Answer by Mgaribay74 Approximately 5000 years ago, an ink for blacking the raised surfaces of pictures and texts carved in stone was developed in China. This early ink was a mixture of soot from pine smoke, lamp oil, and gelatin from animal skins and musk. Other early cultures also developed many colors of ink from available berries, plants and minerals. In an article for the Christian Science Monitor, Sharon J. Huntington describes these other historical inks: About 1,600 years ago, a popular ink recipe was created. The recipe was used for centuries. Iron “salts,” such as ferrous sulfate (made by treating iron with sulfuric acid), was mixed with tannin from gallnuts (they grow on trees) and a thickener. When first put to paper, this ink is bluish-black. Over time it fades to a dull brown. Scribes in medieval Europe (about AD 800 to 1500) wrote on sheepskin parchment. One 12th century ink recipe called for hawthorn branches to be cut in the spring and left to dry.
Ingredients Iron gall ink is essentially created by the chemical reaction between tannic acid and iron(II) sulfate in an aqueous solution. The primary active components in tannin are gallotannic and gallic acid. With iron(II) sulfate, these tannic acids produce a black pigment, called ferrogallotannate or ferrotannate, upon exposure to oxygen. A small amount of pigment forms by reacting with oxygen in the water, but much more pigment is produced after the ink has been applied to paper and exposed to air for several days. Even though iron gall ink has been highly prized for centuries for its durability and rich color, it is known to be chemically unstable, and may, over time, change color or damage the paper on which it is applied (visit ink corrosion for more information). Recent research indicates that a 3:1 ratio of gallotannic acid to iron sulfate produces the most stable inks. Although tannic acid and iron sulfate in water will produce a colored solution, it is not a true ink until
An ink cartridge is a replaceable component of an ink jet printer that contains the ink (and sometimes the print-head itself) that is spread on paper during printing. Each ink cartridge contains one or more partitioned ink reservoirs; certain manufacturers also add electronic contacts and a chip that communicates with the printer. I hope it helps!
