A crystalline structure which consists of variously orientated crystal planes and grain lines and boundaries. A crystalline structure which which has crystals of varying size and randomly organised owing to the growth and production conditions. i.e. heat and time for crystals to develop and form an organised crystalline structure with well organised grain boundaries.
One such example is the Crystal Lattice [linear in all 3-D's] Arrangement of the sodium and chlorine Atoms in table salt.
It is a definite part of all mineral's Atomic Structure.
Glass is amorphous, having no crystalline structure.

glass does not have a crystalline structure but it is still a solid. There are a few solids that don't have crystalline structure such as coal, a block of wood and a brick. Solids that do not have a crystalline structure are known as amorphous solids.
quartz
Super-cooled liquidsA gas takes the shape of its container and fills it, as well. A liquid takes the shape of its container but doesn't fill it necessarily. A solid has a definite volume and shape and usually, but not always, exhibits a crystalline structure. Solids that do not have a crystalline structure are sometimes called "super-cooled liquids" because liquids have no crystalline structure. Glass is a good example of a solid that has no crystalline structure.
Yes, Obsidian is called natural glass. I learned this in science class, so I'm positive.
No
No. By definition, a mineral must have a crystalline structure. Glass does not have a crystalline structure.
Volcanic glass is not a mineral. It's composition is complex, and their is no crystalline structure.
In order to be a mineral, substances need to have fixed internal crystalline structure. Natural glass does not.
Glass is not a subset of quartz because glass does not fit the definition of a mineral in that it has no crystalline structure.
No minerals make up true volcanic glass, as the crystalline structure of minerals did not have time to form before the lava hardened. A mineral must have a crystalline structure.

By definition, a mineral must have a definite crystalline structure. Calcite has this. Glass is amorphous, meaning it does not have such a structure.
quartz
Obsidian, actually a volcanic glass, has no crystalline structure due to its quick solidification.
Perhaps because the glass is in amorphous structure and ceramic is in crystalline structure. Glass is a better conductor of heat than ceramic is.
Volcanic glass is material produced by a volcano that lacks any sort of crystalline structure. While most rocks contain crystals in some form of another, glass does not. Volcanic glass usually forms when molten rock cools too quickly to form a crystalline structure. Examples of volcanic glass include obsidian, ash, pumice, and scoria.
Glass is an amorphous solid meaning it lacks a cohesive crystalline structure but still has organization of molecules where silica binds to oxygen.
