5. Is it too hard to be scratched by quartz?

When the luster, color, and hardness of a mineral have been determined,

you may find that several minerals on the charts fit the description. To

narrow your choice, you can then test other properties of the mineral.

Notice the “remarks” column on the charts. In it, is mentioned anything

that is distinctive about the mineral.

For more complete mineral identification lists and tables, you can use

textbooks, such as _Dana’s Manual of Mineralogy_, revised by C. S.

Hurlbut, Jr., or _Mineralogy_, by E. H. Kraus, W. F. Hunt, and L. S.

Ramsdell.
