GLY 4200 - Lecture 2 –Fall, 2016. 2. Hardness . Hardness may be measured in several ways. Moh’s scale – developed by Austrian mineralogist Friedrich Mohs in 1824. Absolute scales – Brinell, Knoop, Rockwell, Vicker’s. If you closed your eyes and tasted different foods, you could probably determine what the foods are by noting properties such as saltiness or sweetness. . You can also determine the identity of a mineral by noting different properties.. Chapter 5. Minerals of Earth’s Crust. Chapter. 5. Standards. SES3d.

There are over 3000 types of minerals in the Earth’s crust. As you could see with the quartz, often times even the . A pure substance, such as a mineral, can be identified from observations and tests performed to determine its physical properties. These properties are based on the unique structure of the substance.. What is a Mineral?. Must be a solid.. Must occur in nature.. Must have a definable chemical composition (. NaCl. )..
