I. HINTS ON THE STUDY OF MINERALS
A. Aecessories
The following list of articles includes the most important that are
essential for collecting and studying minerals as well as for properly
performing the experiments mentioned in this handbook. They can be
obtained from your loeal dealer or direct from ECKERT MINERAL
RESEARCH.
MAGNIFYING GLASS—A small pocket magnifier of from 7 to 14
power is indispensable for close examination of the specimens.
POCKET KNIFE—For determining the relative hardness of the
minerals,
MAGNET—For the detection of magnetic minerals.
BUNSEN BURNER—Many of the experiments require the applicaté4on of heat. When gas is available a Bunsen Burner is mosé practical.
This is a heating device invented by Professor R. W. Bunsen of Germany. It consists of a straight tube about 5 inches long with one or
more holes at the bottom for the intake of air, Illuminating gas 1s
taken in at the bottom of the tube and the gas and air which are thus
mixed burn at the top with a feebly luminous, but intensely hot flame.
If gas is not available, an alcoho] lamp is satisfactory.
CHARCOAL BLOCK-—A rectangular piece of charcoal about % inch
thick which, when burned, should not leave much of a white ash. The
charcoal block fs used in conjunction with the blowpipe to oxidize or
reduce minerals.
TRIMMING HAMMER—A small light hammer of tempered steel,
with a flat square head and sharp edge for trimming specimens.
COLD CHISEL—A small size chisel] of tempered steel, for working
into cracks or where the point of the hammer will not reach,
STREAK PLATE—A piece of unglazed white porcelain on which the
mineral may be rubbed to show the actual color, as against the surface
color,
COLLECTING BAG—For transporting newly found specimens, preferably made of canvas.
RECORD BOOK—Very important; for recording the complete history of each specimen, the location where it was found, the date, the
characteristics, the experiments and the results.
