The Mohs Hardness Scale

The Agate Festival also featured a demonstration of the Mohs hardness scale, inviting visitors to experience the varying hardnesses of different types of rock via the “scratch test.”

The Mohs scale provides a quantitative way for geologists and rockhounds to identify the hardness of minerals in the field. It ranges from a value of 1 (the softest), for talc, to 10 (the hardest), for diamond. The scale is named after a German geologist/mineralogist, Friedrich Mohs, who introduced it in 1812. The scale is based on the ability of one natural sample of mineral to visibly scratch another mineral.

The Ultraviolet Light Tent

In our Ultraviolet Light Tent will be a display of fluorescent minerals, whose vibrant colors are only visible under ultraviolet light.


Rock Doc

Got a rock you can’t identify or are curious about? The Rock Doc will be available to answer your questions about your mystery rock.
