That would be mica...and it's spelled "quartz"
Begin by taking a look at the mineral's color, Examine the mineral and take note of its surface features,Get out the materials needed for the hardness test (see Things You'll need), The number is the hardness, followed by the characteristics of a mineral of that hardness and an example, Next find out your mineral's luster,Now for the streak test, You can also identify a mineral by the way it breaks. If it breaks along a smooth, flat surface (such as mica), it has cleavage. If your mineral breaks along rough, jagged surfaces, it has fracture. Thats all you need to do.
Cleavage
To determine if a mineral has cleavage or fracture, observe how it breaks. Cleavage is characterized by smooth, planar surfaces along specific directions where the mineral splits easily, reflecting its internal atomic structure. In contrast, fracture results in irregular, jagged surfaces without defined planes. Testing a mineral's breakage pattern can help you identify its cleavage or fracture nature.
A smooth break in a mineral is referred to as "conchoidal fracture." This type of fracture produces curved, shell-like surfaces that resemble the shape of a clam shell. Conchoidal fractures are characteristic of certain minerals, such as quartz and obsidian, and occur when the mineral's atomic bonds break unevenly, creating smooth, glossy surfaces. This feature can be used to identify minerals and is often seen in glassy or amorphous materials.
Cleavage in minerals is the tendency of the mineral to break across a definite plane, creating a smooth surface. Two minerals with cleavage are granite and shale.
cleavage, if a natural property of the mineral (e.g. mica); or a fault, such as in a gemstone.

When a mineral breaks with rough edges, it is called a "fracture." This is different from cleavage, which is when a mineral breaks along smooth, flat planes. Fracture can be described as conchoidal (shell-like), uneven, or fibrous.
cleavage
... because calcite has a regular arrangement of atoms.
when a mineral is broken, if it breaks with smooth shiny sides, then it shows cleavage. If it breaks with rough, uneven sides then it shows fracture.Cleavage is caused by ___________.a)The shape of the mineral.b)The color of the mineral.c)Atomic structure of a mineral.d)The way the mineral is dropped.Undo
A mineral that breaks along a weakly bonded plane is called "cleavage". Cleavage is the tendency of a mineral to break along smooth, flat surfaces determined by its internal atomic structure.
A mineral that breaks into smooth pieces when a tool such as a hammer is used is said to have cleavage. Cleavage is the way a mineral breaks along planes of weakness in its crystal structure, resulting in smooth, flat surfaces. The number and orientation of these cleavage planes are specific to each mineral and can help in identifying the mineral.

Cleavage is the tendency of materials to split along definite structural planes, yielding smooth surfaces. An example is shales or shists.
Cleavage- in geolohy, the tendency of a mineral to splitalong specific planes of weakness to format smooth flatSurface.Fracture- the manner in which a mineral breaks alongeither curved or irregular
