starts to show through the plaster, apply the digging and the scraping gently or
there may be a chance the crystal will be broken. Use the brush to brush away the
loosen plaster powder.

the plaster powder with the brush. A crystal is mined. Repeat the above steps until
all crystals are mined.
Remarks: The kit is intended for kids imitating a geologist digging up crystals. The
digging process has to be done with patience like a real geologists. The activity
may take a few hours or days to complete, depending on the kid's ability. That is
the essence of digging fun.
E. ACTIVITIES 2 - MAKE YOUR OWN CRYSTAL COLLECTION
1. CLEANING THE CRYSTALS

Carefully scrub the dusted crystals with the toothbrush and soapy water.
Afterwards wash them with water and put the cleaned crystals on a piece of
newspaper to dry.
2. STUDYING YOUR CRYSTALS
You can use a magnifying glass to study your crystals. Here is the information
about the crystals included in this kit.
F. ACTIVITIES 3 - MAKE A SPECIAL CRYSTAL GIFT
Why not send the precious stone as gift to your friends or family. Since ancient
times, it has been widely believed that crystals possess mystic power which could
bring good luck and health. A bag is provided in this kit. Simply choose one of the
crystals from your collection. Put it in the bag and
send it as a gift. The recipient will love
this special gift. If you have a rock
tumbler at home, you may tumble
the crystals and have them
polished. They will become more
shiny and transparent after
tumbling, and be a very precious
gift.
G. FUN FACTS
Deep inside our Earth the temperature is very
high at which all rocks and minerals are in melted
form called magma. When this magma rises
towards the Earth’s surface through volcanic
actions, it starts to cool and form solid rock and crystal.
A rock is made up of more than 2 minerals whereas a crystal
is composed of 1 mineral throughout.
Most of the crystals provided in this kit belong to the quartz group. Quartz is
silicon dioxide, SiO2. Quartz is abundant in the Earth's crust and is the chemically
simplest silicates. People use The Mohs Scale to measure the hardness of each
mineral. The softest is talc (1) and the hardest is diamond (10). Quartz has a
hardness of 7.
When you pick up a rock from the backyard. You may be able to find some tiny
crystal embedded in it. If the cooling process is slow, the minerals will form into
large crystals which might be as large as a few feet across. Most of the Earth's
crystals took thousands of years to grow. However, some crystallisation processes
can be so quick that you could watch their formation at home e.g. salt crystal.
Contrary to common understanding, crystals do not have to be clear and
transparent. It all depends on the nature of the forming minerals. But obviously,
beautiful, clear and transparent crystals (gems) are more preferred for making
jewellery.
