Introduction
Purpose
My purpose of this experiment is to find out how crystals are formed and
how they are classified. For a long time, I’ve been interested in crystals, so I’
ve decided this experiment would be perfect for me!

Crystallography

The study of the growth, shape, and geometric characteristics of
crystals is called crystallography. When the conditions are right, each
chemical element and compound can crystallize in a definite and characteristic
form.

Thirty-two classes of crystals are theoretically possible, almost all
common minerals fall into one of about twelve classes, and some classes have
never been seen. The thirty-two classes are grouped into six crystal ...

all have equal length.

Tetragonal

This system comprises crystals with three axes, all perpendicular to one
another; but only two are equal in length.

Orthorhombic

This system comprises crystals with three mutually perpendicular axes,
all of different lengths.

Monoclinic

This system comprises crystals with three axes, all unequal in length,
two o which are not perpendicular to another, but both of which are
perpendicular to the third.

Triclinic

This system comprises crystals with three axes, all unequal in length
and is not perpendicular to one another.

Hexagonal

This system comprises crystals with four axes. Three of these axes are
in a single plane, proportionally spaced, and of equal length. The fourth axis
is perpendicular to the other three. Some crystallographers split the hexagonal
in two, calling the seventh system trigonal or rhombohedral.

Formation of Crystals

Crystals are formed when a liquid becomes solid or when a vapor or
liquid solution becomes ...
