| indentation | 1. The act of indenting or state of being indented. 2. A notch or recess, in the margin or border of anything; as, the indentations of a leaf, of the coast, etc. 3. A recess or sharp depression in any surface. 4. The act of beginning a line or series of lines at a little distance within the flush line of the column or page, as in the common way of beginning the first line of a paragraph. The measure of the distance; as, an indentation of one em, or of two ems. Hanging, or Reverse, indentation, indentation of all the lines of a paragraph except the first, which is a full line.

| Brinell hardness number | A number related to the size of the permanent impression made by a ball indenter of specified size (usually 10 mm in diameter) pressed into the surface of the material under a specified load: where P = applied load in kg, D = diameter of the ball in mm, and d = diameter of the impression in mm.

| hardness | <chemistry> Total concentration of calcium and magnesium ions, expressed as the equivalent concentration (mg/L) of calcium carbonate. Hard water is water that contains lots of calcium carbonate and other minerals. (09 Oct 1997) |
| hardness scale | A qualitative scale in which minerals are classified in order of their increasing hardness, based on the fact that the harder of two materials will scratch the softer and will not be scratched by it. The scale lists 15 substances: 1, talc; 2, gypsum; 3, calcite; 4, fluorite; 5, apatite; 6, orthoclase, periclase; 7, vitreous pure silica; 8, quartz, stellite; 9, topaz; 10, garnet; 11, tantalum carbide, fused zirconia; 12, fused alumina; 13, silicon carbide; 14, boron carbide; 15, diamond. Synonym: Mohs scale. (05 Mar 2000) |
| Knoop hardness number | A number obtained by dividing the load in kg applied to a pyramid-shaped diamond of specific size divided by the projected area of the impression: KHN = L/A, where A= the projected area of the impression in mm2 and L= the load in kg; used for measurements of hardness of any materials, especially very hard and brittle substances such as tooth dentin and enamel.
