- n. A yellow or red crystalline compound, C16H14O6·3H2O, the coloring material of logwood, that is used in dyes, inks, and stains.
Century Dictionary and Cyclopedia
- n. A dye obtained from the logwoodtree, Hæmatoxylon Campechianum, and having the chemical formula C16H14O6 + 2H2O. It forms small crystalline laminæ;, which when pure are colorless and free from bitter or astringent taste. It affords the fine red, blne, and purple colors prepared from logwood by the action of an alkali and the oxygen of the air. The staining-fiuid used in vegetable histology is made by dissolving 35 gram of hematoxylin in 10 grams of water, and adding a few drops of an alum solution, which acts as a mordant in fixing the color. It is one of the best staining-fluids known for the nucleus, coloring it a deep blue. Also hematoxyline, hematin.
