Pumice
Pumice has a dull,
nonmetallic luster but it is
rather hard. It has a high
density, but not very high. It is
not a good conductor of
heat and electricity and it
does not have a streak color.
Pumice is also very brittle.
Galena
Galena has a very shiny,
metallic luster but it is very
dense. It is not magnetic and
is brittle, but it is a good
conductor of heat and
electricity. Galena has a dark
grey streak and is considered
a soft mineral.
Nickel
Nickel is a malleable
substance that is a good
conductor of electricity. It has
a dull, metallic luster but is
soft and has a grey streak.
Nickel is also rather dense
Aluminum
Aluminum is a good conductor
of electricity and is not
magnetic but it does have a
shiny, metallic luster. Aluminum
has a gray/silver streak, a low
density and it is very soft. It can
Sulfur
Sulfur is a very soft substance
with a light yellow streak.
Sulfur is not a conductor of
heat or electricity. Sulfur has
nonmetallic luster and a high
density. It is also very brittle. It
Quartz
Quartz is a hard substance
with no streak. It is not a good
conductor of electricity but it
does have a non-metallic
shiny luster. Quartz is not
magnetic and it has a very
high density.
Copper
Copper is a good conductor of
heat and electricity, it is
malleable and ductile. Copper
is also soft and has a high
density. Copper is not
magnetic and has a dull
metallic shine with a light
