Classroom Minerals
Mineral specimens are cut in a variety of sizes to meet various user needs, with common uses including identification on the part of students, displays to be used during lectures and demonstrations, or as chips for convenient physical identification tests in labs. These mineral specimens also demonstrate a number of classic geological features, such as cleavage, and collections of minerals can be used to test the Mohs hardness of other minerals and compare them.
