Homemade ink 1. Black Ink: There are several ways to make black ink. Here’s an easy one: take one egg yolk‚ ½ teaspoon lamp black‚ ½ cup honey and one teaspoon gum arabic. Lamp black is available commercially or you can make it yourself by holding a plate or any receptacle over a lit candle - it will take some time to collect half a teaspoon though. Mix all of the ingredients to make a thick paste and add enough water to this paste to dilute it so that it flows easily as a fluid. 2. Gall-Iron

5.05 Mixtures and solutions Lab report Ink Chromatography Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sorbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge‚ alterations or changes can be detected in the substance. Chromatography serves mainly as a tool for the examination and

Termite Handedness Summary: Animal behavior is the underlying concept of how living organisms act when presented a certain situation or environment. Understanding animal behavior in simple organisms such as termites can give us basic insight into how animal behavior works. In our experiment we tested termite “handedness” – if termites prefer to turn left or right. We did this by placing a termite in an ink path with a fork in it which would cause the termite to choose between going left or right

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

Wikepedia Book‚ 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;
