MODERATORS
Quartz has an octagonal crystal structure, which is the only thing distinguishing it from regular glass. Both are silicon dioxide.
If you melt quartz and let it cool, it will just be regular glass with an amorphous crystal structure. Conversely, if you melt glass and mix in some ground quartz, it will crystalize around the pattern and become quartz.
