  • Mineral Hardness Scale Ruler

    The Mineral Hardness Ruler is a stimulating visual aid, educates in one phase of mineralogy, and provides the standard ruler measurement scales needed in classes.


    Rockhounds, mineral enthusiasts, students, teachers, geologists, and any one interested in rocks and minerals will find the Mineral Hardness Ruler a handy visual aid for quick information on mineral hardness.



    The two-sided, flexible, glossy, vinyl ruler consists of five scales: three measurement scales and two mineral hardness scales. The measurement scales are in standard ruler measurements of tenths of inches, sixteenths of inches, and millimeters. Mohs' relative hardness numbers are integrated into the inch scales, while a separate scale exists for an absolute mineral hardness scale by Rosiwal.


    On one side of the ruler are pictures of the ten common minerals, in full color, selected by Mohs for his relative hardness scale. On the reverse side of the ruler are six common items with their relative hardnesses. These items, along with known minerals, can be used as a handy field kit to test the relative hardness of an unknown mineral.


    Hardness is one property of a mineral that can be used to distinguish among similar minerals. A given mineral can scratch any other mineral of the same or softer hardness. Over a hundred years ago, the German mineralogist Frederick Mohs devised the relative hardness scale that has found favor with mineralogists for over a century. Others, such as Rosiwal, formed absolute hardness scales using the same minerals as Mohs. For example, diamond, the hardest substance in Nature is not twice as hard as apatite, 10 versus 5, but over twenty thousand times as hard, 140,000 versus 6.5.

  • Under Michigan : The Story of Michigans Rocks and Fossils

    Most people recognize Michigan by its mitten-shaped Lower Peninsula and the Great Lakes embracing the state. Underneath the earth’s surface, however, is equally distinctive evidence of an exciting history. Michigan rests on sedimentary rocks that reach down into the earth’s crust more than fourteen thousand feet—a depth three-and-a-half times deeper than the Grand Canyon. Within these layers of rock rest all sorts of ancient fossils and minerals that date back to the eras when tropical seas spread across Michigan and hot volcanoes flung molten rock into its skies—long before mile-thick glaciers bulldozed over Michigan and plowed through ancient river valleys to form the Great Lakes.

    Under Michigan
    is the first book for young readers about the geologic history of the state and the structure scientists call the Michigan Basin. A fun and educational journey, Under Michigan explores Earth’s geological past, taking readers far below the familiar sights of Michigan and nearby places to explain the creation of minerals and fossils and show where they can be found in the varying layers of rock. Readers will learn about the hard rock formations surrounding Michigan and also discover the tall mountain ridges hidden at the bottom of the Great Lakes. With beautiful illustrations by author Charles Ferguson Barker, a glossary of scientific terms, and charming page to keep field notes, Under Michigan is a wonderful resource for young explorers to use at home, in school, or on a trip across Michigan.
