Properties:‌‌ ‌
‌
The‌‌mineral‌‌Quartz‌‌comes‌‌in‌‌many‌‌
different‌‌colors.‌‌The‌‌more‌‌common‌‌
colors‌‌are‌‌clear,‌‌white,‌‌gray,‌‌purple,‌‌
yellow,‌‌brown,‌‌black,‌‌pink,‌‌green,‌‌and‌‌
red.‌‌Also‌‌when‌‌quartz‌‌takes‌‌its‌‌crystal‌‌
form,‌‌it‌‌will‌‌be‌‌in‌‌a‌‌hexagonal‌‌structure.‌‌
In‌‌addition‌‌to‌‌that‌‌the‌‌chemical‌‌
classification‌‌for‌‌quartz‌‌is‌‌silicate.‌‌ ‌

Interesting‌‌Facts‌‌&‌‌Statistic:‌ ‌
‌
Some‌‌interesting‌‌facts‌‌about‌‌quartz‌‌is‌‌
that‌‌nearly‌‌every‌‌rock‌‌carries‌‌at‌‌the‌‌
minimum‌‌a‌‌small‌‌amount‌‌of‌‌quartz.‌‌In‌‌
addition‌‌to‌‌that,‌‌quartz‌‌contains‌‌pure‌‌
silicon‌‌which‌‌is‌‌used‌‌to‌‌create‌‌many‌‌
types‌‌of‌‌computer‌‌parts.‌‌Lastly,‌‌quartz‌‌
crystals‌‌have‌‌been‌‌used‌‌throughout‌‌
history‌‌as‌‌jewelry‌‌and‌‌decoration.‌ ‌
‌
Composition:‌‌ ‌
‌
Silicon‌‌-‌‌46.74%‌‌‌
‌
Oxygen‌‌-‌‌53.26%‌‌ ‌
‌
‌
Uses:‌ ‌
‌
One‌‌of‌‌the‌‌primary‌‌uses‌‌of‌‌quartz‌‌is‌‌
glassmaking.‌‌The‌‌reason‌‌it‌‌is‌‌mainly‌‌
used‌‌in‌‌glassmaking‌‌is‌‌because‌‌glass‌‌is‌‌
made‌‌from‌‌a‌‌chemical‌‌compound‌‌known‌‌
as‌‌silica‌‌dioxide‌‌which‌‌is‌‌found‌‌in‌‌
quartz.‌‌In‌‌addition‌‌to‌‌that‌‌silica‌‌dioxide‌‌
can‌‌be‌‌melted‌‌and‌‌allowed‌‌to‌‌cool‌‌down‌‌
into‌‌whichever‌‌shape‌‌it‌‌wants‌‌to‌‌be.‌‌
Therefore‌‌this‌‌is‌‌why‌‌we‌‌see‌‌a‌‌lot‌‌of‌‌
things‌‌that‌‌can‌‌be‌‌made‌‌from‌‌glass.‌ ‌

The‌‌mineral‌‌Calcite‌‌usually‌‌comes‌‌in‌‌
the‌‌color‌‌white‌‌but‌‌it‌‌can‌‌also‌‌come‌‌
colorless,‌‌gray,‌‌red,‌‌green,‌‌blue,‌‌
yellow,‌‌brown,‌‌and‌‌orange.‌‌When‌‌it‌‌
comes‌‌to‌‌the‌‌crystal‌‌system‌‌it‌‌is‌‌
classified‌‌as‌‌a‌‌hexagonal‌‌structure.‌‌In‌‌
addition‌‌to‌‌that,‌‌the‌‌chemical‌‌
classification‌‌is‌‌carbonate‌‌mineral.‌‌ ‌
Interesting‌‌Facts‌‌&‌‌Statistic:‌ ‌
‌
Calcite‌‌is‌‌very‌‌easy‌‌to‌‌be‌‌found‌‌in‌‌
the‌‌earth‌‌crust,‌‌and‌‌to‌‌be‌‌more‌‌
specific‌‌it‌‌can‌‌be‌‌located‌‌in‌‌
sedimentary‌‌rocks.‌‌Calcite‌‌can‌‌come‌‌
in‌‌many‌‌different‌‌shapes‌‌and‌‌colors‌‌
which‌‌makes‌‌it‌‌a‌‌popular‌‌choice‌‌
among‌‌collectors.‌ ‌

Use:‌‌ ‌
‌
One‌‌of‌‌the‌‌main‌‌things‌‌Calcite‌‌is‌‌
used‌‌for‌‌is‌‌as‌‌construction‌‌
aggregates,‌‌and‌‌in‌‌production‌‌of‌‌lime‌‌
and‌‌cement.‌‌In‌‌addition‌‌to‌‌that‌‌
calcite‌‌can‌‌also‌‌be‌‌used‌‌in‌‌the‌‌paper‌‌
industry‌‌and‌‌is‌‌also‌‌used‌‌as‌‌filler‌‌and‌‌
coating‌‌material.‌‌It‌‌can‌‌also‌‌be‌‌used‌‌
in‌‌newspapers,‌‌magazines‌‌and‌‌
quality‌‌paper‌‌production.‌ ‌
