represented: hardness, streak, colour, luster,<br />
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 />
property chart, penny, and nail. Sh. wt.<br />

of luster of some minerals is an aid to<br />
identification. This collection provides<br />
examples of both metallic and nonmetallic<br />
types of luster. Contains 15<br />
numbered 1½" natural specimens in a<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 />
Sh. wt. 0.40 kgs.<br />

a coloured streak on unglazed tile<br />
which gives a key to identification<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 />
wt. 0.48 kgs.<br />
