Ink
liquid or paste that contains pigments or dyes
Ink is a gel, sol, or solution that contains at least one colorant, such as a dye or pigment, and is used to color a surface to produce an image, text, or design. Ink is used for drawing or writing with a pen, brush, reed pen, or quill. Thicker inks, in paste form, are used extensively in letterpress and lithographic printing.
Ink can be a complex medium, composed of solvents, pigments, dyes, resins, lubricants, solubilizers, surfactants, particulate matter, fluorescents, and other materials. The components of inks serve multiple purposes; the ink's carrier, colorants, and other additives affect the flow and thickness of the ink and its dry appearance.
History
Many ancient cultures around the world have independently discovered and formulated inks due to the need to write and draw. The recipes and techniques for the production of ink are derived from archaeological analyses or from written texts themselves. The earliest inks from all civilizations are believed to have been made with lampblack, a kind of soot, easily collected as a by-product of fire.
Ink was used in Ancient Egypt for writing and drawing on papyrus from at earliest the 26th century BC. Egyptian red and black inks included iron and ocher as pigments, in addition to phosphate, sulfate, chloride, and carboxylate ions, with lead also used as a drier.
The earliest Chinese inks may date to four millennia ago, to the Chinese Neolithic Period.
This brief starts where responsible research should: with the source description of “Ink” as liquid or paste that contains pigments or dyes. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as liquid or paste that contains pigments or dyes. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 6, 2026. The linked authority identifier is Q127418. The Library of Congress control number is sh85066453. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
