Measuring the Hardness of Minerals
Bushby, Jessica
Australian Primary Mathematics Classroom, v10 n2 p26-29 2005
The author discusses Moh's hardness scale, a comparative scale for minerals, whereby the softest mineral (talc) is placed at 1 and the hardest mineral (diamond) is placed at 10, with all other minerals ordered in between, according to their hardness. Development history of the scale is outlined, as well as a description of how the scale is used and its relationship to other systems. The writer's research notes that although there may be alternative ways of identifying a mineral, Moh's scale is currently the only way of measuring a mineral's hardness. (Contains 1 figure and 1 table.)
