Amorphous solid possess short-range order but no long-range order (e.g. amorphous silica, the short-range order is originated from the tetrahedral bonding between Si and O). Is it possible to have multiple domains with different short-range orders in one amorphous solid?
If so, should we treat this solid as a single phase or multiple phases? Can we detect the existence of multiple domains?
Relative concept: polyamorphism
(It seems that polyamorphism implies that amorphous phases can be distinct from each other.)
