Rationale The history and usage of ink can be traced back to the 18th century B.C.‚ with the utilization of natural plant dyes‚ animal and mineral inks based on such materials. Ink is a pigment in a liquid form or paste form used as colorants and dyes. Ink provides much of the color on paper in the modern world and has many uses in different cultures around the globe. Also‚ they are becoming more and more expensive because of their increasing purposes. Although ink is universally available today‚

of the study Ink is a liquid or paste that contains pigments or dyes 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‚ 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‚ fluorescers‚ and other materials. The components of inks serve many purposes;

Ink Chromatography Lab Background Information Paper chromatography is an analytical method that is used for separating and identifying mixtures of substances into their smaller parts. Paper chromatography works because the ink used contains several dyes (pigments) that when place on porous paper are dissolved in a solvent by capillary action. When the pigments (solutes) are dissolved in the solvent (water & alcohol mixture) they move through the paper at different rates depending on their

Thermochromism Thermochromism refers to the phenomenon of color changes by the agency of heat. Obviously‚ the color changes are made possible by the temperature-induced chemical or physical changes of materials incorporated into the inks. Sometimes‚ the color change occurring at a temperature is permanent‚ and at other times the original color can be regained on cooling. Accordingly‚ we have an irreversible or reversible thermochromic system. The required chemistry can be adopted based
