Marble – metamorphic rock
(rock changed by heat or pressure)
Marble is made from limestone that has been
heated to change it into marble.
It is very
heavy.
It is often white and has
coloured swirls and streaks.
heavy
light
It is easy to polish and make
the surface smooth and shiny.
It is easy to carve because it
is soft and doesn’t crumble
when cut.
Uses:
• sculptures
• buildings
• statues
• chopping
boards
• tiles
Slate – metamorphic rock
(rock changed by heat or pressure)
Slate is made when mudstones called shale
are changed by heat and pressure.
Slate is blue,
purple and
grey in colour.
Slate is
waterproof.
The crystals that
the slate is made
from are arranged
in layers.
It is easy to cut
into thin sheets
due to its layers.
Uses:
roof and floor tiles
walls
decorative gravel
gravestones
Gneiss – metamorphic rock
(rock changed by heat or pressure)
© Siim Sepp
Gneiss is formed when sedimentary and igneous
rocks are exposed to extreme temperatures and
pressure.
Gneiss often has
alternating bands of
colour that make
interesting patterns.
Gneiss has a coarse
texture and is rough
to the touch.
© Michael C Rygel
The bands
are due to
the various
rocks it is
made from.

The quartz in
gneiss makes
it sparkle.
Uses:
• building
construction
• decorative facing
• gravestones
• base for roads
Soapstone – metamorphic rock
(rock changed by heat or pressure)
Soapstone is formed when sedimentary and
igneous rocks are exposed to extreme
temperatures and pressure.
© Ra’ike
Soapstone is
grey, green, pink
or white in colour.
Soapstone is a
soft stone and
is easy to carve
with a sharp
tool such as a
knife.
Soapstone
has a high
resistance
to heat and
acid.
Uses:
bowls
carved objects
lining fireplaces
jewellery
It feels slippery
like soap.
Soapstone can
be polished to a
smooth finish.
