Talc is known for being the softest mineral on earth. It is number 1 on the Mohs hardness scale, and can be easily scratched by a fingernail.Talc is not commonly seen in collections, as it is usually uninteresting and fairly common, although a few deeply colored and crystallized examples are known and well sought after.
Sep 11, 2013· The Mohs hardness scale is based 10 reference minerals, from talc the softest (Mohs hardness of 1), to diamond the hardest (Mohs hardness of 10). It is a relative, or nonlinear, scale. A hardness of 2.5 simply means that the mineral is harder than gypsum (Mohs hardness of 2) and softer than calcite (Mohs hardness of 3).

BACKGROUND Minerals can be identified by various properties.Students will become familiar with mineral characteristics the more they study and examine minerals. Characteristics commonly used to identify minerals include color, hardness, crystal shape, texture, cleavage, density (or specific gravity) and magnetism.The students should be familiar with at least some of these terms.
Sep 01, 2020· The mohs scale is based on 10 reference minerals that have hardness 1 to 10 as follows talc, gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, corundum and diamond.
