cleavage and fracture, specific gravity,<br />

tenacity, and magnetism. Included are 25<br />

numbered mineral specimens (about 1" x<br />

1" in size), streak plate, glass plate, physical<br />

Scale of Hardness<br />

Collection<br />

This collection is the traditional Mohs’<br />

scale, which assigned a “hardness” to 10<br />

key minerals with talc No. 1 (the softest)<br />

and diamond No. 10 (the hardest). The<br />

first nine minerals are included in this<br />

set. The 1" specimens are numbered in a<br />

compartmentalized container.<br />

of that mineral. Examples of this<br />

property can be demonstrated<br />

with this collection. Contains eight<br />

numbered 1" natural specimens in<br />

a compartmentalized container. Sh.<br />
