The term "crystalline" can refer to two slightly different things. The first would be something that is made of crystals. Crystalline can also refer to something that is transparent or resembles crystal.
Ice in a glacier meets the requirements for being a mineral, because it is natural, homogeneous, solid and crystalline, and has a definite chemical fomula. River water is liquid and therefore also not crystalline, so it is not a mineral. If and when the river water freezes into ice (naturally), that ice is a mineral.
No, volcanic glass is not a mineral group. It is a type of igneous rock formed from the rapid cooling of lava without the time for crystallization to occur, resulting in an amorphous (non-crystalline) structure.
A mineral must be a solid, have a definite chemical formula, have a crystalline structure, and be naturally occuring.
Glass would not be considered a mineral because it is not naturally occurring and does not have a crystalline structure.
The four questions used to determine if a substance is a mineral are: Is it naturally occurring? Is it inorganic? Is it a solid? Does it have a specific chemical composition and a crystalline structure?
no however a mineral is a crystalline solid.
When you mix two different solutions. You get crystalline solution.
No. By definition a mineral is a crystalline solid.
The natural shape of a mineral would be its crystalline structure.
Halite is a mineral with a crystalline structure.
Quartz

Quartz
a mineral
It must be naturally occurring and crystalline.
