But what is glass? its SiO². thats Quartz. Quartz is the definition of a crystal and the terms are sometimes used interchangeably.
glass doesnt flow. maybe soda-lime glass acts differently but i doubt it. pure glass is also pure Quartz and thats definitely a crystal
Glass is not quartz. It is an amorphous solid and does not have a regular pattern for the alignment of the atoms required to be a crystal.
thats like saying you crushed and a quartz crystal and messed with its atom alignment, now its no longer a crystal. when a quartz is subjected to heat and high pressures, the crystal forms shock lamellae "shocked quartz". and fused quartz is the same if you ask me. its quartz sand fused together with heat. still a bunch of crystals even if it has an "amorphous structure".
Different molecular order.
